declarativeNetRequest addOrReplaceParams adds a parameter when already present
I'm trying to use DNR to force safe search with Qwant search engine. Under certain circumstances (scenario described below) the search is performed with an API which contains the safe search level in a URL parameter. A typical query URL is https://api.qwant.com/v3/search/web?q=test&count=10&locale=fr_FR&offset=0&device=desktop&tgp=1&safesearch=0&displayed=true&llm=true. I want a DNR rule to force safesearch to be 2 (= strict) (from some javascript code) : { id: 1, priority: 1, action: { type: 'redirect', "redirect": { "transform": { "queryTransform": { "addOrReplaceParams": [{ "key": "safesearch", "value": "2" }] } } } }, condition: { "urlFilter": "api.qwant.com/v3/search", "resourceTypes": ["xmlhttprequest"] }, } When this rule is activated, I end up with a URL with the original safesearch parameter AND the forced one : https://api.qwant.com/v3/search/web?q=test&count=10&locale=fr_FR&offset=0&device=desktop&tgp=1&safesearch=0&displayed=true&llm=true&safesearch=2. To reproduce this request (with the previous DNR rule in place) : navigate to https://www.qwant.com search for some string (test in my case). This displays the list of results ; click the engine button at the top right to display the settings pane ; inspect network request performed by this page ; change the Adult filter in the list -> the results are automatically updated with the new settings. The web request shows URL with the 2 safesearch parameters. I already used addOrReplaceParams in 'standard' contexts (main_frame) and it works just fine. Any hint on what goes on ? Thank you.

Invalid Argument alert when trying to download dataless items
This concerns file provider framework on macOS. Some users of our application (Egnyte.app) report that they have problems downloading dataless files. When a file reaches invalid state, trying to open or download it through Finder results in "Invalid argument" alert (see example-recording.mp4). At the same time our FileProvider extension receives no fetchContents or fetchPartialContents calls. A step-by-step set of instructions to reproduce the problem (if possible) So far we don't have clear reproduction steps. The issue is easily reproducible, for multiple files, for some of our customers. See attached sysdiagnose and recording. What results you expected Our extension receives a request to download the file. File downloads and opens successfully. What results you actually saw No download request made to our File Provider extension. File doesn't open, Finder alert instead. PLEASE NOTE: Before recording and collecting sysdiagnose we installed FileProvider.mobileconfig, slightly modified official profile that we attach. Example reproduction happens 8:33 into full-recording.mp4, around 17:01:18 / 17:01:19 machine’s time. Shared sysdiagnose and recordings come from one of our customers, they permitted us to share the data. In the recording they try to open files with multiple 3rd party applications (Vectorworx, Office PowerPoint) and those opens fail with alerts from those applications. We have similar reports from customers using Adobe apps.

How to consume a dynamic Xcode framework?
I have an Xcode project setup as follows: 3 static libraries 1 framework target, whose Mach-O type is set to Dynamic Library main app target (iOS app) The target dependencies are as follows: In framework's build phase [Link with libraries], I have the 3 libs statically linked. In the main app's build phase [Link with libraries], I have only the framework, which is dynamically linked. As per my understanding: The libs are statically linked to the framework. So, the framework binary would contain code from all the libs. The framework is dynamically linked to the main app (iOS app in this case). So, the main app's binary only has a reference to the framework's binary, which would be loaded in the memory at runtime. Assuming my understanding is correct, I'm stuck with the following problem: All 3 libs build successfully The framework builds successfully The main app target doesn't build. The compilation is successful, but the build fails with linker errors. Please let me know if I am doing something incorrectly, or if a configuration is missing. Below are more details: The linker gives the following error: Undefined symbols for architecture arm64: "StringUtils.GetStr() -> Swift.String", referenced from: dynamic_fw.AppDelegate.application(_: __C.UIApplication, didFinishLaunchingWithOptions: [__C.UIApplicationLaunchOptionsKey : Any]?) -> Swift.Bool in AppDelegate.o "TWUtils.GetNum() -> Swift.Int", referenced from: dynamic_fw.AppDelegate.application(_: __C.UIApplication, didFinishLaunchingWithOptions: [__C.UIApplicationLaunchOptionsKey : Any]?) -> Swift.Bool in AppDelegate.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) And the command shown in the logs for linking phase is: Ld /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator/dynamic-fw.app/dynamic-fw normal (in target 'dynamic-fw' from project 'dynamic-fw') cd /Users/raunit.shrivastava/Desktop/dynamic-fw /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -Xlinker -reproducible -target arm64-apple-ios17.5-simulator -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator17.5.sdk -O0 -L/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/EagerLinkingTBDs/Debug-iphonesimulator -L/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator -L. -L./StringUtils -L./TWFramework -L./TWUtils -L./dynamic-fw -F/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/EagerLinkingTBDs/Debug-iphonesimulator -F/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator -F. -F./StringUtils -F./TWFramework -F./TWUtils -F./dynamic-fw -filelist /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic-fw.LinkFileList -Xlinker -rpath -Xlinker @executable_path/Frameworks -Xlinker -rpath -Xlinker ./\*\* -dead_strip -Xlinker -object_path_lto -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic-fw_lto.o -Xlinker -export_dynamic -Xlinker -no_deduplicate -Xlinker -objc_abi_version -Xlinker 2 -fobjc-link-runtime -L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator -L/usr/lib/swift -Xlinker -add_ast_path -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic_fw.swiftmodule -Xlinker -sectcreate -Xlinker __TEXT -Xlinker __entitlements -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/dynamic-fw.app-Simulated.xcent -Xlinker -sectcreate -Xlinker __TEXT -Xlinker __ents_der -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/dynamic-fw.app-Simulated.xcent.der -framework TWFramework -Xlinker -no_adhoc_codesign -Xlinker -dependency_info -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic-fw_dependency_info.dat -o /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator/dynamic-fw.app/dynamic-fw

Xcode 16 DeviceActivityReport Extensions Require EXAppExtensionAttributes But App Store Rejects Them
I'm experiencing a conflict between Xcode 16's build requirements and App Store validation for DeviceActivityReport extensions. The Issue: Created a DeviceActivityReport extension using Xcode 16's template Extension builds and runs perfectly locally TestFlight upload fails with Apple saying EXAppExtensionAttributes is incorrect for widget extensions When I remove EXAppExtensionAttributes from Info.plist, local builds fail with: "Appex bundle does not define an EXAppExtensionAttributes dictionary" Current Info.plist (works locally, rejected by App Store): EXAppExtensionAttributes EXExtensionPointIdentifier com.apple.deviceactivityui.report-extension NSExtension NSExtensionPointIdentifier com.apple.deviceactivityui.report-extension NSExtensionPrincipalClass $(PRODUCT_MODULE_NAME).ActivityReportExtension The Problem: Xcode 16's "Device Activity Report Extension" template uses fileSystemSynchronizedGroups which appears to require the EX configuration format. But App Store validation rejects this format. Has anyone successfully uploaded a DeviceActivityReport extension created in Xcode 16? Any workarounds for this conflict between local build requirements and App Store validation? Using: Xcode 16.4, Family Controls entitlement (approved), iOS 18.5 SDK Thanks for any insights!

Extra margins around custom keyboard extensions in iOS 26 native apps
Hello, I’ve noticed an issue with custom keyboard extensions in iOS 26 that seems specific to native apps. When a custom keyboard is opened in apps like Messages, Notes, or Safari, there’s an extra strip of native grey space around the left, right, and top edges of the keyboard. This extra margin cannot be rendered over by the keyboard’s own views. Interestingly, this behaviour does not occur in third-party apps like Instagram. It also wasn’t present in earlier iOS versions. The result is that keyboards with custom or non-grey backgrounds look visually inconsistent (they appear framed by unwanted grey). Has anyone else run into this? Is this a known change in iOS 26, or could it be a bug? Any guidance or official clarification would be appreciated. Thanks!

Background shield application reliability
Hello! I am working on a screentime app and wondering if anyone has had success achieving reliable background shield application while using com.apple.ManagedSettingsUI.shield-configuration-service? I recently switched from com.apple.deviceactivity.shield-configuration (which worked reliably but isn't accepted by TestFlight) and have not found any consistency getting shields to apply while the app is backgrounded. I believe this is a known limitation of ManagedSettingsUI and want to know if there are successful workarounds or any specific patterns/timing that improve consistency?

Crashes launching app from Camera control button
I'm using the LockedCameraCaptureExtension to launch my Camera app from the camera button. Some of our users report our app crashing a few seconds after being launch from the camera button. The call stack is something inside BoardServices [BSServicesConfiguration activateXPCService] I'm not sure how to investigate or fix this, anyone else having the same issue? Basically in my LockedCameraCaptureExtension when it loads I just call openApplication on the LockedCameraCaptureSession to launch into my app. @main struct captureExtension: LockedCameraCaptureExtension { var body: some LockedCameraCaptureExtensionScene { LockedCameraCaptureUIScene { session in Button(action: { Task { await openCamera(session: session) } }, label: { Text("Open Camera") }) .buttonStyle(PlainButtonStyle()) .task { await openCamera(session: session) } } } private func openCamera(session: LockedCameraCaptureSession) async { try? await session.openApplication(for: NSUserActivity(activityType: "com.mycompany.camera")) } }

How to Handle IME Not Generating Receipt in Sandbox IAP
Question: In the sandbox environment, I attempted to perform an In-App Purchase within an IME (Input Method Extension) using a sandbox test account. The purchase flow completed successfully, and I received the success callback. However, I encountered an issue: no receipt file is generated. I tried checking with both the main app’s bundle and the IME’s bundle, but the receipt file was not found in either case. When I attempted to refresh the receipt using SKReceiptRefreshRequest, it failed with an exception (error code: 0). I would appreciate any guidance on how to resolve this issue.

Live Caller ID Lookup — What’s the automatic refresh cadence for config/PIR parameters? Best way to prompt updates?
Hi Apple team, We’re shipping a Live Caller ID Lookup extension on iOS 18 and have a question about the automatic refresh of configuration/PIR parameters. Questions 1. Is there any documented interval/TTL (min/max) for the system’s automatic refresh of /config and PIR parameters, or is it entirely opportunistic (battery/network/usage)? I can’t find a cadence in the IdentityLookup docs. 2. Does iOS honor server cache headers (e.g., Cache-Control/Expires) to influence when it re-fetches? 3. Which events also trigger a refresh (enable/disable in Settings, OS/app update, device reboot, token/epoch change)? 4. Are there rate limits or best-practice limits for calling refreshExtensionContext and refreshPIRParameters?

Embed/Do Not Embed & Mach-O type
My Xcode project has the following configuration: 1 iOS app target 1 Xcode framework target (mach-o-type "Dynamic Library") 5 static libraries Dependencies: All the static libraries are target dependencies of the framework. The framework is the only target dependency of the iOS app. For the iOS app target, within the General tab > Frameworks, Libraries & Embedded content, I've set the framework as "Do not embed" So now I have a dynamic framework which won't be copied to the .app bundle in the build output. As per my understanding, this should result in a runtime error, dyld should not be able to find the framework files as they were not embedded in the final .app bundle. But regardless, my app runs without any errors, using all the methods exposed by the framework. What is the correct understanding here? What exactly does Embed/Do not embed mean (apart from excluding the files from .app bundle) When both settings are specified, is there any priority or precedence of one setting over the other?

Questions about using App Extension communication with host apps on iOS 26 (Xcode 26)
Hello, I have a few questions regarding the documentation here: Can this method described in the article be built with Xcode 26 and run on iOS 26? Or is it restricted to run only on iOS 26, since AppExtensionPoint appears to be available starting from iOS 26? Does this approach allow two apps under the same Team ID to communicate with each other? Does this approach also allow two apps under different Team IDs to communicate with each other? Is it mandatory to implement EXAppExtensionBrowserViewController and obtain user consent before using this method to exchange information? In our implementation, we followed the documentation. Inside EXAppExtensionBrowserViewController, we were able to see the Generic Extension from another app and enabled the permission. However, we still get the following error: Failed to connect: Error Domain=NABUExtensionConnector Code=1 "No matching extension found" UserInfo={NSLocalizedDescription=No matching extension found} Could someone clarify whether this is expected behavior, or if we are missing an additional configuration step? Thanks in advance!

Chrome extension => Safari web extension packager
"The Safari web extension packager enables you to package and distribute your Safari extensions using App Store Connect from any web browser, without requiring a Mac or access to Xcode." I upload the unzipped folder I'd test in Chrome://extensions to the Safari web extension packager in App store connect. I get error: Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier. The only solution i've seen to this error involves xcode/a mac, being without which doesn't help

Call Directory Number Matching Inconsistency Across Regions
[Question] Inconsistent Call Directory number matching across regions (Japan, Taiwan, U.S.) We’re developing a Call Directory extension and observed inconsistent number matching depending on carrier region and number format. Environment Device: iPhone (iOS 26.0) Call Directory Extension: Custom implementation Carrier A: Japan carrier SIM Carrier B: Taiwan carrier SIM Numbers added to Call Directory patterns: +81 120 580 2XXX +81 704 336 2XXX Observed Behavior (Japan Carrier SIM) Incoming call from +81 120 580 2XXX → Caller name not displayed (Call Directory match failed). Entering 0120 580 2XXX in the Phone app dialer → Name displayed correctly. Incoming call from +81 704 336 2XXX → Caller name displayed correctly. Entering 070 4336 2XXX in the Phone app dialer → Name displayed correctly. Observed Behavior (Taiwan Carrier SIM) Entering +81 120 580 2XXX in the dialer → Name not displayed until the call button is pressed. Entering +81 704 336 2XXX in the dialer → Name displayed immediately, before the call is placed. Steps to Reproduce For Japan carrier: Use a device running iOS 26 with a Japanese SIM card. Add the following numbers to the Call Directory extension: +81 120 580 2XXX and +81 704 336 2XXX Receive an incoming call from +81 120 580 2XXX → ❌ Caller name not displayed. Open the Phone app and enter 0120 580 2XXX → ✅ Caller name displayed. Receive an incoming call from +81 704 336 2XXX → ✅ Caller name displayed. Open the Phone app and enter 070 4336 2XXX → ✅ Caller name displayed. For Taiwan carrier: 7. Insert a Taiwan SIM card (keep the same Call Directory patterns). 8. Enter +81 120 580 2XXX → ❌ Name not shown until the call button is pressed. 9. Enter +81 704 336 2XXX → ✅ Name shown immediately. Expected Result For both numbers: Caller name from Call Directory should display consistently: a) On incoming calls. b) When entering the full number in the dialer (before pressing call). Behavior should be consistent across regions (Japan, Taiwan, United States). Actual Result Region / Carrier Number Pattern Incoming Call Dialer (Local Format) Japan +81 120 580 2XXX ❌ Not shown ✅ Shown (0120 580 2XXX) Japan +81 704 336 2XXX ✅ Shown ✅ Shown (070 4336 2XXX) Taiwan +81 120 580 2XXX N/A ❌ Not shown until call Taiwan +81 704 336 2XXX N/A ✅ Shown immediately Questions How should numbers be formatted or stored in the Call Directory patterns so that they match both incoming calls and dialer input consistently across regions? Are there region-specific number normalization rules (e.g., Japan’s 0-prefixed local dialing or Taiwan’s international format handling)? Is there an official guideline or recommendation for formatting phone numbers in Call Directory extensions (e.g., E.164 vs local format) to ensure consistent matching? Notes The inconsistent behavior appears to be related to how iOS normalizes numbers per carrier region and local dialing conventions. In Japan, incoming calls from mobile numbers starting with 070 match correctly, while 0120 (toll-free) fails unless entered in local format.

First installation of the extension - sending messages to the background script from the event handler in the content script does not work
After the first installation (out of AppStore) of the extension in the browser, the content script is correctly inserted into the page (twice for some reason) and a message is sent from the root of the content script to the background script, which responds correctly. However, if an event handler is registered within the content script, within which the message is also sent to the background script, it will never reach the background script. window.addEventListener("message", function (event) { // We only accept messages from ourselves if (event.source !== window) { return; } if (event.data.source && event.data.source === appIdentification) { browser.runtime.sendMessage(event.data); } }, false); It does not matter with what delay the event handler is called (i.e. the background script is not asleep). If I refresh the page or close and reopen the browser and reload the page, everything works correctly and the message sent from the event handler is already delivered to the background script. The event handler is used so that the extension code is uniform for all browsers (Chrome, Safari, Edge, Opera, Firefox), i.e. it is not intended to use externally_connectable for sending messages from the webpage directly to the background script, which Safari should support. The expected behavior is that the extension will work even after the first installation, as is the case with other browsers. Procedure: Enter the test website: https://www.mssf.cz/testapp/check_client.aspx Do the initial installation of the extension (could be downloaded from here: https://1drv.ms/f/c/76f4c93826df41a0/Ej5MQX9ctyhHv_P9_t_6uAwB05ET-nzXuMhPeu56nOgkWg?e=cudqRJ) Set a breakpoint in the event handler for "message" within the content script, open the background script and set a breakpoint in the event handler for onMessage Click on the "Validate certificate" button on the page loaded in point 1 Step through the content script to the point where the message is sent to the background script, the breakpoint within the background script is never hit, which is an error, the message should come to the background script

Background script in the form of a service worker cannot be debugged
If the extension uses manifest v3 and a background script in the form of a service worker, then in Safari it is not possible to open the background script debugging window. If I expand the Developer menu in Safari, there is nothing under Web Extension Background Data (or disappear after click), which is an error. In other browsers (Edge, Chrome, Opera, Firefox) this works correctly. If I switch the background script back to non-persistent script mode, everything works fine and from the Developer menu and the Web Extension Background Data submenu I am able to open the background script debugging window for the extension. Am I doing something wrong?

Share Extension Lifetime and SwiftData
I have an app that uses a Share Extension that allows the user to share videos, from Files and Photos etc., the video URL and some related data is then persisted with SwiftData and synchronized with CloudKit. This code has worked consistently for a long time although recently, with iOS 26 and recent builds of iOS 18, I have observed that the video is either not saved to SwiftData (iOS 26.0), or available locally when the app is opened on the same device where the share occurred, but not synchronized to other devices (iOS 18.7 and iOS 26.1 beta). Assuming the video is opened locally after being shared into the app, it is typically synchronized with CloudKit to other devices although it's not as reliable as it should be. Is there a reliable approach in the Share Extension to ensure that the data is saved to the local SwiftData database and then synchronized with CloudKit. I suspect it could be that the lifetime of the Share Extension has become even more constrained in recent OS updates that the process ends before it has the opportunity to save and synchronize the data. Any thoughts on how to ensure this is reliable would be greatly appreciated. The data saved is not too large as it consists only of the video URL and not the data of the video itself.

Share Extension / Sandbox Issue: sandboxd deny(1) hid-control
I'm developing a Share Extension for a macOS Electron application that allows users to share files from Finder to our application using the system Share menu. The extension compiles, signs, and notarizes successfully, but crashes during initialization due to sandbox restrictions blocking hid-control operations required by NSApplication. The Share Extension crashes during initialization with the following sandbox violation: Process: ShareExtension [pid] Identifier: com.xxxxxxxxxxxx.xxxxxxxxx.extension Operation: hid-control I would appreciate guidance on: The proper entitlements for third-party Share Extensions with App Sandbox Alternative approaches if Share Extensions have fundamental limitations for third-party developers Any documentation or sample code demonstrating Share Extensions outside the App Store

declarativeNetRequest addOrReplaceParams adds a parameter when already present
I'm trying to use DNR to force safe search with Qwant search engine. Under certain circumstances (scenario described below) the search is performed with an API which contains the safe search level in a URL parameter. A typical query URL is https://api.qwant.com/v3/search/web?q=test&count=10&locale=fr_FR&offset=0&device=desktop&tgp=1&safesearch=0&displayed=true&llm=true. I want a DNR rule to force safesearch to be 2 (= strict) (from some javascript code) : { id: 1, priority: 1, action: { type: 'redirect', "redirect": { "transform": { "queryTransform": { "addOrReplaceParams": [{ "key": "safesearch", "value": "2" }] } } } }, condition: { "urlFilter": "api.qwant.com/v3/search", "resourceTypes": ["xmlhttprequest"] }, } When this rule is activated, I end up with a URL with the original safesearch parameter AND the forced one : https://api.qwant.com/v3/search/web?q=test&count=10&locale=fr_FR&offset=0&device=desktop&tgp=1&safesearch=0&displayed=true&llm=true&safesearch=2. To reproduce this request (with the previous DNR rule in place) : navigate to https://www.qwant.com search for some string (test in my case). This displays the list of results ; click the engine button at the top right to display the settings pane ; inspect network request performed by this page ; change the Adult filter in the list -> the results are automatically updated with the new settings. The web request shows URL with the 2 safesearch parameters. I already used addOrReplaceParams in 'standard' contexts (main_frame) and it works just fine. Any hint on what goes on ? Thank you.

Invalid Argument alert when trying to download dataless items
This concerns file provider framework on macOS. Some users of our application (Egnyte.app) report that they have problems downloading dataless files. When a file reaches invalid state, trying to open or download it through Finder results in "Invalid argument" alert (see example-recording.mp4). At the same time our FileProvider extension receives no fetchContents or fetchPartialContents calls. A step-by-step set of instructions to reproduce the problem (if possible) So far we don't have clear reproduction steps. The issue is easily reproducible, for multiple files, for some of our customers. See attached sysdiagnose and recording. What results you expected Our extension receives a request to download the file. File downloads and opens successfully. What results you actually saw No download request made to our File Provider extension. File doesn't open, Finder alert instead. PLEASE NOTE: Before recording and collecting sysdiagnose we installed FileProvider.mobileconfig, slightly modified official profile that we attach. Example reproduction happens 8:33 into full-recording.mp4, around 17:01:18 / 17:01:19 machine’s time. Shared sysdiagnose and recordings come from one of our customers, they permitted us to share the data. In the recording they try to open files with multiple 3rd party applications (Vectorworx, Office PowerPoint) and those opens fail with alerts from those applications. We have similar reports from customers using Adobe apps.

Invalid Argument alert when trying to download dataless items
This concerns file provider framework on macOS. Some users of our application (Egnyte.app) report that they have problems downloading dataless files. When a file reaches invalid state, trying to open or download it through Finder results in "Invalid argument" alert (see example-recording.mp4). At the same time our FileProvider extension receives no fetchContents or fetchPartialContents calls. A step-by-step set of instructions to reproduce the problem (if possible) So far we don't have clear reproduction steps. The issue is easily reproducible, for multiple files, for some of our customers. See attached sysdiagnose and recording. What results you expected Our extension receives a request to download the file. File downloads and opens successfully. What results you actually saw No download request made to our File Provider extension. File doesn't open, Finder alert instead. PLEASE NOTE: Before recording and collecting sysdiagnose we installed FileProvider.mobileconfig, slightly modified official profile that we attach. Example reproduction happens 8:33 into full-recording.mp4, around 17:01:18 / 17:01:19 machine’s time. Shared sysdiagnose and recordings come from one of our customers, they permitted us to share the data. In the recording they try to open files with multiple 3rd party applications (Vectorworx, Office PowerPoint) and those opens fail with alerts from those applications. We have similar reports from customers using Adobe apps. More info in FB19462434

How to consume a dynamic Xcode framework?
I have an Xcode project setup as follows: 3 static libraries 1 framework target, whose Mach-O type is set to Dynamic Library main app target (iOS app) The target dependencies are as follows: In framework's build phase [Link with libraries], I have the 3 libs statically linked. In the main app's build phase [Link with libraries], I have only the framework, which is dynamically linked. As per my understanding: The libs are statically linked to the framework. So, the framework binary would contain code from all the libs. The framework is dynamically linked to the main app (iOS app in this case). So, the main app's binary only has a reference to the framework's binary, which would be loaded in the memory at runtime. Assuming my understanding is correct, I'm stuck with the following problem: All 3 libs build successfully The framework builds successfully The main app target doesn't build. The compilation is successful, but the build fails with linker errors. Please let me know if I am doing something incorrectly, or if a configuration is missing. Below are more details: The linker gives the following error: Undefined symbols for architecture arm64: "StringUtils.GetStr() -> Swift.String", referenced from: dynamic_fw.AppDelegate.application(_: __C.UIApplication, didFinishLaunchingWithOptions: [__C.UIApplicationLaunchOptionsKey : Any]?) -> Swift.Bool in AppDelegate.o "TWUtils.GetNum() -> Swift.Int", referenced from: dynamic_fw.AppDelegate.application(_: __C.UIApplication, didFinishLaunchingWithOptions: [__C.UIApplicationLaunchOptionsKey : Any]?) -> Swift.Bool in AppDelegate.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) And the command shown in the logs for linking phase is: Ld /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator/dynamic-fw.app/dynamic-fw normal (in target 'dynamic-fw' from project 'dynamic-fw') cd /Users/raunit.shrivastava/Desktop/dynamic-fw /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -Xlinker -reproducible -target arm64-apple-ios17.5-simulator -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator17.5.sdk -O0 -L/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/EagerLinkingTBDs/Debug-iphonesimulator -L/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator -L. -L./StringUtils -L./TWFramework -L./TWUtils -L./dynamic-fw -F/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/EagerLinkingTBDs/Debug-iphonesimulator -F/Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator -F. -F./StringUtils -F./TWFramework -F./TWUtils -F./dynamic-fw -filelist /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic-fw.LinkFileList -Xlinker -rpath -Xlinker @executable_path/Frameworks -Xlinker -rpath -Xlinker ./\*\* -dead_strip -Xlinker -object_path_lto -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic-fw_lto.o -Xlinker -export_dynamic -Xlinker -no_deduplicate -Xlinker -objc_abi_version -Xlinker 2 -fobjc-link-runtime -L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator -L/usr/lib/swift -Xlinker -add_ast_path -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic_fw.swiftmodule -Xlinker -sectcreate -Xlinker __TEXT -Xlinker __entitlements -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/dynamic-fw.app-Simulated.xcent -Xlinker -sectcreate -Xlinker __TEXT -Xlinker __ents_der -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/dynamic-fw.app-Simulated.xcent.der -framework TWFramework -Xlinker -no_adhoc_codesign -Xlinker -dependency_info -Xlinker /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Intermediates.noindex/dynamic-fw.build/Debug-iphonesimulator/dynamic-fw.build/Objects-normal/arm64/dynamic-fw_dependency_info.dat -o /Users/raunit.shrivastava/Library/Developer/Xcode/DerivedData/dynamic-fw-foqtqhpopkmoapfufzxbfloamnpr/Build/Products/Debug-iphonesimulator/dynamic-fw.app/dynamic-fw

Xcode 16 DeviceActivityReport Extensions Require EXAppExtensionAttributes But App Store Rejects Them
I'm experiencing a conflict between Xcode 16's build requirements and App Store validation for DeviceActivityReport extensions. The Issue: Created a DeviceActivityReport extension using Xcode 16's template Extension builds and runs perfectly locally TestFlight upload fails with Apple saying EXAppExtensionAttributes is incorrect for widget extensions When I remove EXAppExtensionAttributes from Info.plist, local builds fail with: "Appex bundle does not define an EXAppExtensionAttributes dictionary" Current Info.plist (works locally, rejected by App Store): EXAppExtensionAttributes EXExtensionPointIdentifier com.apple.deviceactivityui.report-extension NSExtension NSExtensionPointIdentifier com.apple.deviceactivityui.report-extension NSExtensionPrincipalClass $(PRODUCT_MODULE_NAME).ActivityReportExtension The Problem: Xcode 16's "Device Activity Report Extension" template uses fileSystemSynchronizedGroups which appears to require the EX configuration format. But App Store validation rejects this format. Has anyone successfully uploaded a DeviceActivityReport extension created in Xcode 16? Any workarounds for this conflict between local build requirements and App Store validation? Using: Xcode 16.4, Family Controls entitlement (approved), iOS 18.5 SDK Thanks for any insights!

Extra margins around custom keyboard extensions in iOS 26 native apps
Hello, I’ve noticed an issue with custom keyboard extensions in iOS 26 that seems specific to native apps. When a custom keyboard is opened in apps like Messages, Notes, or Safari, there’s an extra strip of native grey space around the left, right, and top edges of the keyboard. This extra margin cannot be rendered over by the keyboard’s own views. Interestingly, this behaviour does not occur in third-party apps like Instagram. It also wasn’t present in earlier iOS versions. The result is that keyboards with custom or non-grey backgrounds look visually inconsistent (they appear framed by unwanted grey). Has anyone else run into this? Is this a known change in iOS 26, or could it be a bug? Any guidance or official clarification would be appreciated. Thanks!

Background shield application reliability
Hello! I am working on a screentime app and wondering if anyone has had success achieving reliable background shield application while using com.apple.ManagedSettingsUI.shield-configuration-service? I recently switched from com.apple.deviceactivity.shield-configuration (which worked reliably but isn't accepted by TestFlight) and have not found any consistency getting shields to apply while the app is backgrounded. I believe this is a known limitation of ManagedSettingsUI and want to know if there are successful workarounds or any specific patterns/timing that improve consistency?

Crashes launching app from Camera control button
I'm using the LockedCameraCaptureExtension to launch my Camera app from the camera button. Some of our users report our app crashing a few seconds after being launch from the camera button. The call stack is something inside BoardServices [BSServicesConfiguration activateXPCService] I'm not sure how to investigate or fix this, anyone else having the same issue? Basically in my LockedCameraCaptureExtension when it loads I just call openApplication on the LockedCameraCaptureSession to launch into my app. @main struct captureExtension: LockedCameraCaptureExtension { var body: some LockedCameraCaptureExtensionScene { LockedCameraCaptureUIScene { session in Button(action: { Task { await openCamera(session: session) } }, label: { Text("Open Camera") }) .buttonStyle(PlainButtonStyle()) .task { await openCamera(session: session) } } } private func openCamera(session: LockedCameraCaptureSession) async { try? await session.openApplication(for: NSUserActivity(activityType: "com.mycompany.camera")) } }

How to Handle IME Not Generating Receipt in Sandbox IAP
Question: In the sandbox environment, I attempted to perform an In-App Purchase within an IME (Input Method Extension) using a sandbox test account. The purchase flow completed successfully, and I received the success callback. However, I encountered an issue: no receipt file is generated. I tried checking with both the main app’s bundle and the IME’s bundle, but the receipt file was not found in either case. When I attempted to refresh the receipt using SKReceiptRefreshRequest, it failed with an exception (error code: 0). I would appreciate any guidance on how to resolve this issue.

Live Caller ID Lookup — What’s the automatic refresh cadence for config/PIR parameters? Best way to prompt updates?
Hi Apple team, We’re shipping a Live Caller ID Lookup extension on iOS 18 and have a question about the automatic refresh of configuration/PIR parameters. Questions 1. Is there any documented interval/TTL (min/max) for the system’s automatic refresh of /config and PIR parameters, or is it entirely opportunistic (battery/network/usage)? I can’t find a cadence in the IdentityLookup docs. 2. Does iOS honor server cache headers (e.g., Cache-Control/Expires) to influence when it re-fetches? 3. Which events also trigger a refresh (enable/disable in Settings, OS/app update, device reboot, token/epoch change)? 4. Are there rate limits or best-practice limits for calling refreshExtensionContext and refreshPIRParameters?

Embed/Do Not Embed & Mach-O type
My Xcode project has the following configuration: 1 iOS app target 1 Xcode framework target (mach-o-type "Dynamic Library") 5 static libraries Dependencies: All the static libraries are target dependencies of the framework. The framework is the only target dependency of the iOS app. For the iOS app target, within the General tab > Frameworks, Libraries & Embedded content, I've set the framework as "Do not embed" So now I have a dynamic framework which won't be copied to the .app bundle in the build output. As per my understanding, this should result in a runtime error, dyld should not be able to find the framework files as they were not embedded in the final .app bundle. But regardless, my app runs without any errors, using all the methods exposed by the framework. What is the correct understanding here? What exactly does Embed/Do not embed mean (apart from excluding the files from .app bundle) When both settings are specified, is there any priority or precedence of one setting over the other?

Questions about using App Extension communication with host apps on iOS 26 (Xcode 26)
Hello, I have a few questions regarding the documentation here: Can this method described in the article be built with Xcode 26 and run on iOS 26? Or is it restricted to run only on iOS 26, since AppExtensionPoint appears to be available starting from iOS 26? Does this approach allow two apps under the same Team ID to communicate with each other? Does this approach also allow two apps under different Team IDs to communicate with each other? Is it mandatory to implement EXAppExtensionBrowserViewController and obtain user consent before using this method to exchange information? In our implementation, we followed the documentation. Inside EXAppExtensionBrowserViewController, we were able to see the Generic Extension from another app and enabled the permission. However, we still get the following error: Failed to connect: Error Domain=NABUExtensionConnector Code=1 "No matching extension found" UserInfo={NSLocalizedDescription=No matching extension found} Could someone clarify whether this is expected behavior, or if we are missing an additional configuration step? Thanks in advance!

Chrome extension => Safari web extension packager
"The Safari web extension packager enables you to package and distribute your Safari extensions using App Store Connect from any web browser, without requiring a Mac or access to Xcode." I upload the unzipped folder I'd test in Chrome://extensions to the Safari web extension packager in App store connect. I get error: Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier. The only solution i've seen to this error involves xcode/a mac, being without which doesn't help

Call Directory Number Matching Inconsistency Across Regions
[Question] Inconsistent Call Directory number matching across regions (Japan, Taiwan, U.S.) We’re developing a Call Directory extension and observed inconsistent number matching depending on carrier region and number format. Environment Device: iPhone (iOS 26.0) Call Directory Extension: Custom implementation Carrier A: Japan carrier SIM Carrier B: Taiwan carrier SIM Numbers added to Call Directory patterns: +81 120 580 2XXX +81 704 336 2XXX Observed Behavior (Japan Carrier SIM) Incoming call from +81 120 580 2XXX → Caller name not displayed (Call Directory match failed). Entering 0120 580 2XXX in the Phone app dialer → Name displayed correctly. Incoming call from +81 704 336 2XXX → Caller name displayed correctly. Entering 070 4336 2XXX in the Phone app dialer → Name displayed correctly. Observed Behavior (Taiwan Carrier SIM) Entering +81 120 580 2XXX in the dialer → Name not displayed until the call button is pressed. Entering +81 704 336 2XXX in the dialer → Name displayed immediately, before the call is placed. Steps to Reproduce For Japan carrier: Use a device running iOS 26 with a Japanese SIM card. Add the following numbers to the Call Directory extension: +81 120 580 2XXX and +81 704 336 2XXX Receive an incoming call from +81 120 580 2XXX → ❌ Caller name not displayed. Open the Phone app and enter 0120 580 2XXX → ✅ Caller name displayed. Receive an incoming call from +81 704 336 2XXX → ✅ Caller name displayed. Open the Phone app and enter 070 4336 2XXX → ✅ Caller name displayed. For Taiwan carrier: 7. Insert a Taiwan SIM card (keep the same Call Directory patterns). 8. Enter +81 120 580 2XXX → ❌ Name not shown until the call button is pressed. 9. Enter +81 704 336 2XXX → ✅ Name shown immediately. Expected Result For both numbers: Caller name from Call Directory should display consistently: a) On incoming calls. b) When entering the full number in the dialer (before pressing call). Behavior should be consistent across regions (Japan, Taiwan, United States). Actual Result Region / Carrier Number Pattern Incoming Call Dialer (Local Format) Japan +81 120 580 2XXX ❌ Not shown ✅ Shown (0120 580 2XXX) Japan +81 704 336 2XXX ✅ Shown ✅ Shown (070 4336 2XXX) Taiwan +81 120 580 2XXX N/A ❌ Not shown until call Taiwan +81 704 336 2XXX N/A ✅ Shown immediately Questions How should numbers be formatted or stored in the Call Directory patterns so that they match both incoming calls and dialer input consistently across regions? Are there region-specific number normalization rules (e.g., Japan’s 0-prefixed local dialing or Taiwan’s international format handling)? Is there an official guideline or recommendation for formatting phone numbers in Call Directory extensions (e.g., E.164 vs local format) to ensure consistent matching? Notes The inconsistent behavior appears to be related to how iOS normalizes numbers per carrier region and local dialing conventions. In Japan, incoming calls from mobile numbers starting with 070 match correctly, while 0120 (toll-free) fails unless entered in local format.

First installation of the extension - sending messages to the background script from the event handler in the content script does not work
After the first installation (out of AppStore) of the extension in the browser, the content script is correctly inserted into the page (twice for some reason) and a message is sent from the root of the content script to the background script, which responds correctly. However, if an event handler is registered within the content script, within which the message is also sent to the background script, it will never reach the background script. window.addEventListener("message", function (event) { // We only accept messages from ourselves if (event.source !== window) { return; } if (event.data.source && event.data.source === appIdentification) { browser.runtime.sendMessage(event.data); } }, false); It does not matter with what delay the event handler is called (i.e. the background script is not asleep). If I refresh the page or close and reopen the browser and reload the page, everything works correctly and the message sent from the event handler is already delivered to the background script. The event handler is used so that the extension code is uniform for all browsers (Chrome, Safari, Edge, Opera, Firefox), i.e. it is not intended to use externally_connectable for sending messages from the webpage directly to the background script, which Safari should support. The expected behavior is that the extension will work even after the first installation, as is the case with other browsers. Procedure: Enter the test website: https://www.mssf.cz/testapp/check_client.aspx Do the initial installation of the extension (could be downloaded from here: https://1drv.ms/f/c/76f4c93826df41a0/Ej5MQX9ctyhHv_P9_t_6uAwB05ET-nzXuMhPeu56nOgkWg?e=cudqRJ) Set a breakpoint in the event handler for "message" within the content script, open the background script and set a breakpoint in the event handler for onMessage Click on the "Validate certificate" button on the page loaded in point 1 Step through the content script to the point where the message is sent to the background script, the breakpoint within the background script is never hit, which is an error, the message should come to the background script

Background script in the form of a service worker cannot be debugged
If the extension uses manifest v3 and a background script in the form of a service worker, then in Safari it is not possible to open the background script debugging window. If I expand the Developer menu in Safari, there is nothing under Web Extension Background Data (or disappear after click), which is an error. In other browsers (Edge, Chrome, Opera, Firefox) this works correctly. If I switch the background script back to non-persistent script mode, everything works fine and from the Developer menu and the Web Extension Background Data submenu I am able to open the background script debugging window for the extension. Am I doing something wrong?

Share Extension Lifetime and SwiftData
I have an app that uses a Share Extension that allows the user to share videos, from Files and Photos etc., the video URL and some related data is then persisted with SwiftData and synchronized with CloudKit. This code has worked consistently for a long time although recently, with iOS 26 and recent builds of iOS 18, I have observed that the video is either not saved to SwiftData (iOS 26.0), or available locally when the app is opened on the same device where the share occurred, but not synchronized to other devices (iOS 18.7 and iOS 26.1 beta). Assuming the video is opened locally after being shared into the app, it is typically synchronized with CloudKit to other devices although it's not as reliable as it should be. Is there a reliable approach in the Share Extension to ensure that the data is saved to the local SwiftData database and then synchronized with CloudKit. I suspect it could be that the lifetime of the Share Extension has become even more constrained in recent OS updates that the process ends before it has the opportunity to save and synchronize the data. Any thoughts on how to ensure this is reliable would be greatly appreciated. The data saved is not too large as it consists only of the video URL and not the data of the video itself.

Share Extension / Sandbox Issue: sandboxd deny(1) hid-control
I'm developing a Share Extension for a macOS Electron application that allows users to share files from Finder to our application using the system Share menu. The extension compiles, signs, and notarizes successfully, but crashes during initialization due to sandbox restrictions blocking hid-control operations required by NSApplication. The Share Extension crashes during initialization with the following sandbox violation: Process: ShareExtension [pid] Identifier: com.xxxxxxxxxxxx.xxxxxxxxx.extension Operation: hid-control I would appreciate guidance on: The proper entitlements for third-party Share Extensions with App Sandbox Alternative approaches if Share Extensions have fundamental limitations for third-party developers Any documentation or sample code demonstrating Share Extensions outside the App Store
