Apple notification description: notificationType： The type that describes the In-App Purchase or external purchase event for which the App Store sends the version 2 notification. App Store Server Notifications 2.0+ string notificationType Possible Values CONSUMPTION_REQUEST A notification type that indicates that the customer initiated a refund request for a consumable In-App Purchase or auto-renewable subscription, and the App Store is requesting that you provide consumption data. For more information, see Send Consumption Information. When the developer receives the refund request notification and sends the refundPreference, they say: GRANT_PRORATED You prefer that the App Store grants a prorated refund. Discussion Use these values in the refundPreference field of a ConsumptionRequest. The following constraints apply to the GRANT_PRORATED option: If the product is a consumable or non-consumable In-App Purchase or a non-renewing subscription, you may include a consumptionPercentage value in the ConsumptionRequest. Question: Requesting a refund for a non-consumable type does not send a notification to the developer. However, when a developer sends a refund preference, they can still send a GRANT_PRORATED request for a non-consumable type.

On iOS 18, when XCUITest encounters an "Application has not loaded accessibility" error after the 60 second timeout, it performs an undocumented auto-recovery ("Setting up automation session") instead of halting the test as documented. This leaves the XCUITest framework in a corrupted state, causing subsequent tests in the same session to fail with unexpected behavior. Expected Behavior (per Apple documentation): Any failure in the launch sequence will be reported as a test failure and the test will be halted at that point. Actual Behavior: XCUITest waits 60 seconds for accessibility to load Logs "Application has not loaded accessibility" error Instead of halting, performs "Setting up automation session" (auto-recovery) Test continues with corrupted framework state Subsequent tests in the same session fail with phantom element queries Steps Run XCUITest suite on a real iOS 18 device Have an app with moderately heavy initialization (e.g., synchronous network operations during bootstrap) Observe intermittent "accessibility not loaded" errors When error occurs, subsequent tests fail with unexpected behavior Test Logs Evidence First test (accessibility failure + recovery): t = 11.11s Wait for accessibility to load t = 71.14s Capturing diagnostic spindump t = 76.24s Assertion Failure: Application 'com.example.app' has not loaded accessibility t = 76.26s Setting up automation session ← Undocumented recovery t = 77.29s Tear Down Second test (corrupted state): t = 35.01s Tap "signin-button" t = 35.55s Waiting for "bannerButtonStackFirstItem" ← Query NOT in test code! t = 40.58s Assertion Failure: Failed to find element The second test executes element queries that do not exist in its source code, indicating leaked/corrupted state from the previous test's failed recovery. Note: The tearDown() method terminates the app but cannot reset the internal state of the XCUITest framework itself, so corruption persists across tests. We are observing this behavior consistently on iOS 18 real devices. We would like to know: Is this a known issue with XCUITest on iOS 18? Is anyone experiencing similar "accessibility not loaded" failures followed by auto-recovery? Is the "Setting up automation session" recovery behavior intentional or a bug? Is there a recommended workaround to prevent framework state corruption between tests?

Calling dlopen then dlclose causes an increase in the amount of memory used by the program. If I create a loop that calls dlopen / dlclose repeatedly on the same dynamic library, memory usage increases continuously. Is this a bug, or am I using dlopen / dlclose incorrectly? I can reproduce this by modifying the sample code in the Apple Developer docs Creating Dynamic Libraries. If I modify Runtime.c, changing the line void *lib_handle = dlopen(lib_name, RTLD_NOW); to add the infinite loop, as below: void *lib_handle = dlopen(lib_name, RTLD_NOW); for (int ii = 0; ; ++ii) { printf("loop %i\n", ii); int close_err = dlclose(lib_handle); printf("close error: %i\n", close_err); printf("dlopen(%s, RTLD_NOW)\n", lib_name); lib_handle = dlopen(lib_name, RTLD_NOW); } then opening and closing the dynamic library will succeed, but memory usage (as reported by top) will rapidly increase. I'm running on x86_64 macOS 13.6.6. Full code for the modified Runtime.c is attached, the rest of the code is available in the Apple Developer docs. Any suggestions? Many thanks, Chris Runtime.c

I used to develop iPhone apps about a decade ago and am now back at it with an iPhone and companion Apple Watch app. Why does it suck so bad? I a must be doing something wrong, but what I am doing is out of the box. The majority of the time when I go to build on the watch I get: Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters. Which I then first try to force quit the app on the watch and if that does not work, reboot the watch (which is pretty ridiculous). I tried Gemini and it gave me the following explanation: This is arguably the single most frustrating error in the entire watchOS development ecosystem. As an expert, I can tell you that you are not doing anything wrong; you are fighting a fragile architecture. Here is the technical breakdown of why this happens and a workflow to mitigate it without constant reboots. The Technical "Why" This error message reveals that the issue lies in the CoreDevice (and formerly usbmuxd) infrastructure, specifically in the secure transport layer. The "Tunnel" Failure: Xcode attempts to establish a secure, encrypted tunnel (DTXConnection) to the Apple Watch to push the debugger and the app binary. Unlike the iPhone, which can sustain a high-bandwidth connection easily, the Watch aggressively manages its radios (Bluetooth vs. WiFi vs. AWDL) to save battery. The "Handshake" Timeout: If the Watch is on Bluetooth (Low Energy) when Xcode initiates the tunnel, the bandwidth is insufficient. The system tries to escalate the connection to WiFi (or Apple Wireless Direct Link). If this negotiation takes even a few milliseconds too long—due to 2.4GHz interference, router mDNS configuration, or the Watch CPU being throttled—the handshake times out. The "Previous Preparation Error": This is the insidious part. Once the handshake fails once, Xcode’s device service caches that failure state for the device UUID. It marks the device as "unreachable" to prevent the IDE from hanging indefinitely on subsequent tries. Why you see it constantly: You aren't actually triggering a new connection attempt; you are hitting the cached "failed" state immediately. Unfortunately, the solutions it gives me are: The "Wired Proxy" Method (Most Reliable) This is the gold standard for watchOS debugging. Do not rely on "Connect via Network" for the Watch directly if you can avoid it. Disable WiFi on your Mac (temporarily) or ensure the Mac and iPhone are on the exact same SSID. Plug your iPhone into the Mac via USB. Ensure the Watch is paired to that iPhone. Result: Xcode will tunnel the instructions through the USB connection to the Phone, and the Phone acts as a high-bandwidth proxy to the Watch. This eliminates the "Mac-to-Watch" WiFi negotiation failure point. Do you hit this regularly? What do you do to make for a smooth development and deployment process? Or is it really this fragile? Thanks for any help! Bryan

Hi there! I am not a coder, but I built an app in ADALO just for in-house use in my company, PetroImaging. The app looked the way I wanted it to in the preview mode in ADALO, but when my app was approved and ready for download in the app store, a lot of content was missing. Many buttons that linked to screens were just gone - even though they were there in the preview and the buttons are formatted correctly in adalo. How can I get my content that I need back on my app so the employees can being using it?

I have an MAUI based application build and ready for the distribution. The application is working perfectly in the debug environment on the simulator. So the app logic is working correctly as expected without any errors. But when a release build is created the application crashes on the simulator and physical device. I'm developing the application using .Net 10 framework with target device iOS 26. The Supported OS Platform is set to 15.0 in csproj file. Also have the entitlements. plist file set in the csproj. The IDe used is Visual Studio Code for Mac (MAC OS). The application uses MSAL for the login / authentication purpose (Microsoft.Identity.Client) and SQLite Database (Sqlite-net-pcl) Message: Kindly guide me to build the application correctly in release version and get the ipa file ready for the in house distribution that could be deployed correctly on the physical device with iOS 18 / 26.

This is from an Xcode generated file. var values: [String] = [] let exp = Expectation() let c = pub.filter { $0 != nil }.map { $0! }.sink( The second line gives an error: "'Expectation' cannot be constructed because it has no accessible initializers". My best guess that Expectation objects come from some other Apple Swift Testing function, but I don't know where.

I've suddenly started seeing hundreds of the same block of four error messages (see attached image) when running my app on my iOS device through Xcode. I've tried Cleaning the Build folder, but I keep seeing these messages in the console but can't find anything about them. Phone is running iOS 26.1. Xcode is at 16.4. Mac is on Sequoia 15.5. The app is primarily a MapKit SwiftUI based application.

I am using macOS’s /bin/date command, both in Terminal and via AppleScript (do shell script). I noticed inconsistent behaviour with the %N format specifier for nanoseconds: • On some Macs, date +%s%N returns numeric nanoseconds as expected. • On other Macs, the same command returns a literal N or fails when coerced to a number. • This occurs across different macOS versions and on both Intel and Apple Silicon machines. My understanding is that macOS ships BSD date, which does not officially document %N. I am trying to determine: 1. Is %N in /bin/date officially supported on macOS, and if so, on which versions? 2. If %N is not supported, what is Apple’s recommended, portable method for obtaining sub-second or millisecond timestamps in shell scripts or AppleScript across all macOS versions?

I am located in Taiwan and recently updated my Mac to the latest OS and installed the newest Xcode. However, I’m experiencing extremely slow download speeds when trying to add the iOS 26.2 Simulator Runtime (approx. 8GB) via Xcode > Settings > Platforms. It is currently downloading at a rate of only 500MB per hour, which is impractical. I have checked the official downloads page but couldn't find a standalone DMG link for this specific version. My questions are: Is there a direct download link (DMG) available on the Apple Developer portal for the iOS 26.2 Simulator? If no direct link exists, are there any recommended methods to accelerate the download? (e.g., using terminal commands or changing DNS settings). Any help or direct URLs would be greatly appreciated. Thank you!

I am developing CarPlay addition on our app. Which is distributed with the Enterprise In distribution method, so we do not have a product in the App Store. I am wondering if CarPlay support can be provided in applications distributed with the Enterprise in distribution method? If this is not possible, I will inform management that this is not possible. I am waiting for your answers, thanks.

Background Assets can support a maximum of 200G. Will the Apple server perform file comparison? For example, file0 is included in both a.aar file and b.aar file. On the Apple server, does it occupy twice the size of a single file?

Hello, "This issue is blocking App store approval" I have tried pushing my application to Appstore. However it has been rejected on the following ground: _"As we discussed, the app uses or references the following non-public or deprecated APIs: Frameworks/CommonLibrary.framework/CommonLibrary Symbols: • _SecCertificateIsValid The use of non-public or deprecated APIs is not permitted, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms."_ I have scanned the app using "strings" tool & "otool -ov" tool. But they have come out clean. No Non-public or deprecated APIs detected. Please advise which tool can be used to scan the CL to locate where the deprecated API or non-public API lies and also how to rectify the same. Thanks Saikat Bakshi.

Hello, According to documentation, the App Store does not re-download the entire app when updating, but instead generates an update package containing only the changed content compared to the previous version. I’d like to clarify the following points: 1. Granularity of file changes If only part of a large file changes, does the update package include the entire file, or does it patch only the modified portions within that file? 2. Guideline on separating files The documentation recommends separating files that are likely to change from those that are not. How should this be interpreted in practice? 3. Verifying the diff result Is there a way for developers to check the actual diff result of the update package generated by the App Store without submitting the app? Is there a diff command tool or comparison method closer to the actual App Store update process? 4. Estimating update size during development For apps with large-scale resources, minimizing update size is critical. Are there any tools or best practices to estimate the size of the update package before submitting to the App Store? Any clarification or reference materials would be greatly appreciated. Thank you.

How to replicate: Design a icon in icon composer Save it and put the .icon file in your project, then in your targets put the name of the .icon file in there. Either clean build folder or restart IDE One Error: unable to open dependencies file (/Users/user/Library/Developer/Xcode/DerivedData/project-fqrfzzkwgrutdabmcqjeupvyetci/Build/Intermediates.noindex/project.build/Debug/project.build/assetcatalog_dependencies_thinned) And one warning: Icon export exited with status 255, signal 0 Is this a known issue or a easy fix? Or is it a issue on my end? Thanks

Hi, I am developing IOS(Android App) with React Native. I am very confused about cocoapods and pod and how to correctly install it on my new Macbook Pro M4. I am not using bash but I am using zsh. Note, actuallywhich pod return nothing During the preparation of my environment, it say CocoaPods is one of the dependency management system available for iOS. CocoaPods is a Ruby gem. You can install CocoaPods using the version of Ruby that ships with the latest version of macOS. the web site show two commands gem install cocoapods sudo gem install cocoapods I saw another command as well brew install cocoapods During different processes, I experienced several time the following error (Command 'pod install failed) Command pod install failed. └─ Cause: pod install --repo-update --ansi exited with non-zero code: 1 Then I am confused about cocoapods and pod. Are both he same? With my previous MacBook pro, I spend time to install cocoapod on my profile because Ruby was not the latest version on the system. But apparently, on my new Macbook Pro M4, the command ruby -v return (as well) ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.arm64e-darwin25] The current stable version is 4.0.0. I bought a new macbook pro M4 and I reinstalled node and all package for Rect Native 0.81 a expo 54 excepted cocoapods. Now, I need to configure the push notification and it's time to install cocoapods as it's require here But on my new macbook pro, I would like to make sure I do it correctly and I kindly ask your help and recommandation to install Ruby and cocoapods/pod Q1: Should I install cocoapods with brew install cocoapods or gem install cocoapods? Q2: what's is the difference or the common point with cocoapods and pod? Cocoapod web site said If using the default Ruby included with macOS, installation will require you to use sudo when installing gems As ruby -v print 'ruby 2.6.10p210', I suppose, I should not install cocoapod with sudo You can use a Ruby Version manager such as RVM or rbenv to manage multiple Ruby versions, or you can use Homebrew to install a newer Ruby with brew install ruby. As far I understand, I should not install cocoapods with the Ruby version of the system, then I suppose the command Q3: Will 'brew install cocopads' install the latest version on my profile? Will it upgrade the system version Q4: What will do the command brew install rbenv ruby-build rbenv install 3.2.2 (or better: rbenv install 4.0.0) in comparison with brew install ruby My guess I suppose that the following will help, but it would nice if you could correct me and clarify # All should be done in my profile brew install rbenv ruby-build echo 'eval "$(rbenv init - bash)"' >> ~/.zprofile source ~/.zprofile rbenv install 4.0.0 # rbenv global 4.0.0 # What is it? ruby -v gem install cocoapods Q5: But then, what about pod and the error message Command pod install failed. As you can see, I am a bit confused and I would appreciate your clarification I thanks you for your help and clarification and I wish you a happy new years

I am encountering an issue where the application running on a physical device does not reflect the most recent source changes. Observed behavior On the device, the application behaves as if an older binary is running. Specifically: Newly added debug UI labels do not appear. The logs still show old debug prints instead of new ones. Steps taken to ensure a clean install: Changed the bundle identifier Set a new display name (the app still showed the old display name when I click run). Deleted the app manually from the device before every reinstall. Build and install steps Performed multiple clean builds with a fresh Derived Data path. Built from terminal using xcodebuild (Debug configuration, physical device target, automatic provisioning). Installed using: xcrun devicectl device install app Verified: The updated source files are listed under Compile Sources and compiled from the expected path. The bundled Info.plist includes the new bundle identifier and display name. Installation output confirms new bundle identifier. Question What could cause a newly built and installed application to run with behavior from an older binary? Are there recommended ways to verify that the device is actually launching the latest installed build, and to ensure stale binaries are not being executed? Any guidance on additional diagnostics or misconfigurations to check would be appreciated.

I am trying to add promotional offers in my iOS App. The signature is being verified through a google cloud function. My user id, signature, and product and offerIds return perfect. Promotional offer appears in the payment sheet as well. When applying for payment, the "ding" sound comes as well. But then I get the UIAlert with Unable to Purchase Contact developer. Error code in logs is 3903

I need to install the AirPlay profile on an iphone to watch decrypted traffic in ATS for development work on CarPlay. The documentation for ATS says to click "Utilities -> Download Profiles -> AirPlay Diagnostic Mode". When I do this, it brings up a file dialog, presumably to select a location to download. But nothing happens. The other profiles launch a web browser and download the .mobileconfig profile. How do I get the AirPlay profile? Am I misunderstanding how this is supposed to work? I found ATSAssetsInfoDefault.plist which references these files. And they all have https://developer.apple.com/services-account/download?path=/iOS/iOS_Logs/... except the AirPlay profile, which is type "slug" and just says ats-airplay-diagnostic-mode-profile. Is this a bug in the app?

I have a Apple Developer accounts for development purposes only and that is also used for testing builds via TestFlight. Is the Age Ratings Responses updates due by the end of January 2026 still required even to send builds to TestFlight?
