Dear Team, We have developed a macOS app using Unity (6000.0.51f1) that includes learning activities, assessments/tests, audio recording, and video playback functionalities. For security and content protection, we want to restrict the ability for users to capture screenshots or screen recordings of the app (especially via the built-in Cmd+Shift+5 / Screenshot toolbar). We have attempted several approaches, but they have not been reliable. We would appreciate guidance from Apple or the developer community on the feasibility of this requirement. Our requirements: Block or disable screenshots/screen recordings (particularly the built-in Cmd+Shift+5) for the app. Preferably achieve this using public APIs so that the app remains App Store compatible and passes review. If full blocking is not possible, then at least ensure that any captured content appears blank/black for sensitive sections of the app. Additionally, we would like our app’s window behavior to work like other apps do: Red button → Close the application completely. Yellow button → Minimize the application to the Dock. Green button → Maximize to full screen while still allowing access to the Dock and menu bar. Any advice, best practices, or references to relevant documentation would be highly valuable. Thank you for your support.

Hi Apple Dev community, I want to ask if CallKit and CXCallDirectoryProvider (with addBlockingEntryWithNextSequentialPhoneNumber) doesn't work for 3rd party Phone apps. Is this a known issue that CallKit doesn't work on 3rd party iOS Phone apps (like WhatsApp, etc)? Thank you.

im being hacked im not a developer im being illgeally enrolled into mdm/ developer ive been being hacked for a while and its gotten to the point that my life has been put in danger and my family had to file a missing persons report because i went missing for 6 weeks my calls even to 911 are being intercepted and i have a software license agreement that i shouldnt have my identity has been stolen and i cant get off this developer mdm thing

I would like the function in the calendar app to be able to assign a status to the set appointment, such as unconfirmed or pending.

Our VoIP app receives PushKit notifications successfully (callservicesd Delivering 1 VoIP payload appears in logs). However, the app is consistently terminated by the system when running in the background or killed state. The crash is caused by iOS expecting a reportNewIncomingCall to CallKit, but the system reports: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Killing app because it never posted an incoming call to the system after receiving a PushKit VoIP push.' *** Assertion failure in -[PKPushRegistry _terminateAppIfThereAreUnhandledVoIPPushes], PKPushRegistry.m:349 Key Observations: VoIP pushes arrive and are delivered to the app. In foreground, some methods work and CallKit UI sometimes appears. In background/killed state, app is always terminated before CallKit UI shows. Logs confirm the system requires CallKit to be reported immediately inside pushRegistry(_:didReceiveIncomingPushWith:for:completion:). Steps to Reproduce: Run the app with VoIP + CallKit integration. Put app in background (or kill it). Send a VoIP push. Observe system logs and crash: callservicesd: Delivering 1 VoIP payload(s) to application UrgiDoctor: Apps receiving VoIP pushes must post an incoming call via CallKit... error: Killing VoIP app because it failed to post an incoming call in time. Expected Behavior: On receiving a VoIP push, CallKit UI (Accept / Decline screen) should always appear. App should not be killed if reportNewIncomingCall is called in time. Actual Behavior: CallKit UI never appears in background/killed state. App is force-terminated by iOS before user can accept/decline the call. Request: Guidance on the correct sequence for calling reportNewIncomingCall and completionHandler() in pushRegistry. Clarification if any changes in iOS 17/18 affect PushKit + CallKit behavior. Best practices for ensuring CallKit UI always appears reliably after a VoIP push. Environment: iOS 18.5 Simulator + Device Xcode 16.4 Using PushKit + CallKit with VoIP entitlement

Currenty, I'm developing a blocking and call identity call. In iOS 18, everything works fine, I can show log to debug inside my Callkit extensions But when my app run in iOS 26, I cant even turn on my caller id extension, I'm not able to debug because I dont see any log from my extensions.

Hello, In production, a large number of users experience outgoing call reporting fails with the following error: com.apple.CallKit.error.requesttransaction Code=2 The iOS version doesn't matter, errors are present in v15-26 Details My CXProvider held as a global singleton, so it’s unlikely to be deinited. There is no explicit call to CXProvider.invalidate() in the app. If I manually invalidate the CXProvider, I observe the expected failure when trying to create an outgoing call (com.apple.CallKit.error.requesttransaction error 2). However, If I recreate the CXProvider after the error, outgoing calls are reported correctly. Many users trigger the providerDidReset delegate method (CXProviderDelegate) before this error. According to the documentation, providerDidReset can be called by the system, and we are supposed to end all active calls, but the documentation doesn't suggest recreating the CXProvider. Question Should I recreate CXProvider after providerDidReset and forget about that, or could this error be caused by something else?

Hello everyone, I would like to know if there is any way for an iOS app to automatically access a user’s total Screen Time (for example, daily or weekly usage) and then share this with friends so they can compare results, like in a “Screen Time battle”? Thanks you very much for you help!

For my app, I would like to offer the user an option to enter a value in any currency and have it converted to their 'home' currency with the correct exchange rate. I saw that the Apple Calculator is offering that functionality and was wondering if there is a way to also get the exchange rate with out of the box tools? I know that there are several API providers out there that offer the current exchange rate for any currency but I am looking for a solution that is free of charge. Max

When we compile our app using Xcode 26 and run it on iOS 26, we encounter a strange crash where the crashing thread shows no stack trace. After inspecting the registers, we have initially traced it to the Google Mobile Ads SDK. When we disable the initialization of the Google Mobile Ads SDK, the app no longer crashes. However, running the Google Mobile Ads SDK demo app on iOS 26 alone does not cause any issues; the crash only occurs once it is integrated into our app. We also tried enabling Address Sanitizer and Zombie Objects but found no valuable clues. Could you advise what other methods or tools we can use to further diagnose this issue? Additionally, when we compile the app with Xcode 15 and run it on iOS 26, everything works fine without crashes. app-2025-09-19-161044.ips.txt

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?

I have prepared a NSSpellServer spelling and grammar checker for Slovenian proofing in macOS. My proofing service gets used when I explicitly set keyboard spelling language to "Slovenian (Besana)" (my proofing tool). When I set keyboard language to Automatic by Language, system does the language detection. Since it has limited support for Slovenian language, it doesn't recognize the text as Slovenian and never asks my proofing service to check the spelling. It does consult my proofing service for spelling suggestions and when it does, I see the language parameter there is set to anything but Slovenian. Is it possible to install own language detector to macOS? Or, place some language dictionary files somewhere, the system could use to extend language detection to new languages?

I have prepared a NSSpellServer spelling and grammar checker for Slovenian proofing in macOS. My proofing service gets used when I explicitly set keyboard spelling language to "Slovenian (Besana)" (my proofing service). However, no matter how I set the Check Grammar With Spelling option or Check Grammar checkbox in the TextEdit.app or Mail.app, my proofing service does not get any request for grammar checking. I am supporting checkString call for Unified checking and checkingTypes never contains NSTextCheckingTypeGrammar flag. When using legacy API before Unified checking support, the checkGrammarInString is never called either. If I do the grammar regardless the checkingTypes parameter, the app shows grammar mistakes correctly. But that is bad UX. Need to follow user demand for with grammar or without grammar. I don't know what am I doing wrong? On my home iMac v11 it actually works. No idea what I did there to make it work. Just worked. On my working Mac Mini v13 it won't check grammar. On another MacBook Pro v15, it won't check grammar either. Apps do check spelling with my proofing service. But not grammar. Same apps do grammar checking with stock AppleSpelling.service just fine. I have checked my Info.plist, using Hardened Runtime, have empty Entitlements, to no avail. Was there some new grammar API introduced after macOS v11 Big Sur, I should implement? Is there some specific Entitlement, signature, notarization I should perform to get going? Some documentation I am missing?

Hello Having trouble getting associated domain to work in our project. It was working when we used Branch, but our company wants to host the domain ourselves. This is a multi-scheme project, using .xcconfig files to define the correct entitlement per Build. The relevant entitlement file has: com.apple.developer.associated-domains applinks:bm.ddcas.ai in the ....{other irrelevant test associated domains....} The project Team and App ID are taken from the Identifiers screen where the Identifier capabilities has 'associated domains' ticked on. I've also checked elsewhere on AppleDeveloper/Connect to be sure. When we used Branch with domain key app links: bmstores.app.link this worked fine. With https://bm.ddcas.ai (our own host) which is publicly available and has an aasa file in both the main directory and /.well-known, typing this in safari or anything just doesn't attempt to link to the App. The iPhone is in developer mode, and using the developer menu associated domains diagnostic tool, typing https://bm.ddcas.ai results in the diagnostic saying 'The url is a Universal Link for the app with identifier **********.***etc (the app is installed on real iPhone 12, iOS 18.6.2 and my Xcode is 16.4) However, it just doesn't work if we type in https://bm.ddcas.ai and results in a Safari message of '400 not found' and the 'nginx' shows. We have read innumerable Apple Dev posts and StackOverflow posts, as well as several step by step 'how to's' online but this just isn't working. The aasa file is at https://bm.ddcas.ai/apple-app-site-association and is setup as follows: { "applinks": { "apps": [], "details": [ { "appID": "{my Team ID}.{my App ID}", "paths": [ "*" ], "components": [ { "/": "/verification", "?": { "verification_code": "[A-Za-z0-9]{6}" }, "comment": "Matches verification code path" } ] } ] } } Our Server guys say the website (bm.ddcas.ai) is public and hosted, it just doesn't have a /verification path as they say it should redirect before reaching that. Also, our Android redirect works using this site, so this appears to be something specific Apple code is looking for. What, please, are we likely to be missing as it does not seem obvious from the Apple documentation or any of the resources I have checked online. Normally we can figure anything out, but getting nowhere here so the help is appreciated.

I have four apps currently deployed on the App Store. One of these apps crashes on launch when running on iOS 26, but functions as expected on iOS 18 and earlier versions. I am seeking to understand what changes in iOS 26 might be causing this issue. When running the app in debug mode on devices with iOS 26 using Xcode 16.1, the app crashes. The crash log references libobjc-trampolines.dylib, suggesting a potential issue with the Objective-C runtime. Has anyone else encountered a similar issue? AGX: AGX: agxa_device_template.hpp:1467:setupCompiler: *** FATAL: driver shader binary file not found in (null) for extension g15p!!! D [yHZ]: added warning: [MEDIUM]: SW04: A debugger is attached to the App. D [ProbeCallbacks]: [IXGUARD] debugger detected objc[1461]: couldn't dlopen libobjc-trampolines.dylib: dlopen(/usr/lib/libobjc-trampolines.dylib, 0x0106): tried: '/usr/lib/system/introspection/libobjc-trampolines.dylib' (no such file, not in dyld cache), '/usr/lib/libobjc-trampolines.dylib' (no such file), '/private/preboot/Cryptexes/OS/usr/lib/libobjc-trampolines.dylib' (open() failed with errno=24), '/usr/lib/libobjc-trampolines.dylib' (no such file, not in dyld cache) What steps can I take to resolve this crash? Thank you for your assistance.

我完全复用了官方wwdc的Alarmkit的demo。测试过程发现12，13pro闹钟完全正常，15pro和16pro闹铃时间不对，经常不响，而且在设置中切换市时区时会立马响。这是api的bug么

Hi, after updating to iOS 26 I'm encountering an issue where the FamilyActivityPicker no longer opens. No errors are shown in the console, it just never shows up. It works fine pre iOS 26. I've never had any issues with the picker showing up until iOS 26. My latest update was rejected because of this issue, but I've changed nothing in the code. Is anyone else experiencing this?

My app is a VoIP softphone for Mac that allows people to make phone calls to a regular phone numbers. The app exists since before Mac App Store. The app declares itself to the system as capable of handling tel: URLs. Until now, people could change the default handler for tel URLs in FaceTime settings (Default for calls). In macOS Tahoe 26, this doesn't seem to be possible any more. That option is gone from the FaceTime settings. Is it completely gone or has it been moved somewhere else? If there is no UI control for this any more, is it possible to change it programmatically?

Hi, Since I updated my phone to 23A341, my Call filtering app is not blocking calls anymore. Same release checked on iOS 18 phone, it is working. I still see the callkit logs into the Console showing that numbers are loaded into the iOS-managed SQlite DB but the calls are not blocked nor identified. Anyone with the same issue? BR
