dlopen problems with debug build, macOS SDK 15, and ASAN
Hello, There seems to be a regression with macOS SDK 15 and dynamically loading libraries if Address Sanitizer is turned on. Seems to only affect Debug builds, and .frameworks. I've also reported this via the Feedback Assistant: FB16513866 Here's a minimal repro, if anyone is interested: https://gist.github.com/peter-esik/6b00432e411be85333e14ae7d953966e I thought I'd post this here, as according to my web searches, this isn't a very well-known bug at this point.

React native app crash on TestFlight
Good day everyone. I have a react native app which works on dev mode on my device - Iphone 13 pro version: 18.5, but when deployed to TestFlight and installed on same device it crashes when ever I click on any TextInput. I downloaded the crash file but finding it difficult to pinpoint the problem. I want to know what the problem is, if it's related to an installed package or code base or any other. Any help will be appreciated!!! Thanks. crashlog.crash

iOS AppPresser app logs out automatically after any period of time (Android works fine)
Hello, Thank you for taking the time to read this and hopefully helping me. https://apps.apple.com/gb/app/gdl-graded-darts-leagues/id1592502150 I created a mobile app using AppPresser that is connected to my WordPress website. The iOS app is logging users out when they close the app and go back to it. The login session does not persist, and users are forced to log in again frequently. This happens at any time period between closing and opening the app. This only happens on iOS — Android keeps the session active as expected. I don't know if I've included this post in the correct topic, sorry. Thanks again for any ideas and assistance!

lldb-dap closes connection
If I build an x64 binary on my M4 Mini, when I try to debug it using Visual Studio remote debugging the connection is closed, which means I cannot debug my code in x64 mode. I need to be able to do this as I have architecture specific code. I have Rosetta installed. FWIW I have the same issue with lldb-mi :( David

LibGDX/MobiVM App refuses to launch on iOS 26.0.1
Hello, currently I am having trouble releasing an app because it crashes/does not launch on iOS 26.0.1. We have uploaded apps in the past so I tried building one of them with our current toolchain. I use Xcode 16.4, Kotlin version 2.0.0, LibGDX 1.13.1 and robovm/MobiVM 2.3.23. I uploaded the build to TestFlight and tested with physical devices running iOS 18.5 and 26.0.1. It runs fine on 18.5 but refuses to launch on the 26.0.1 device. I cannot retrieve a crash log or .ips file because none is written. When I write a Console log while the app crashes/does not launch I get no hints as to why it does so. Do you maybe have additional ideas as to why it keeps not launching on iOS 26.0.1?

Can I get notified when my watchOS app is terminated by the system (e.g. watchdog)?
Hi all, I’m developing a watchOS app and have seen cases where the app is terminated by the system — for example, due to CPU usage limits being exceeded (watchdog termination). Here’s a portion of one of the crash reports: Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: CAROUSEL 2343432205 <RBSTerminateContext| domain:10 code:0x8BADF00D explanation:[app<app_name>:898] Failed to terminate gracefully after 5.0s ProcessVisibility: Foreground ProcessState: Running WatchdogEvent: process-exit WatchdogVisibility: Foreground WatchdogCPUStatistics: ( "Elapsed total CPU time (seconds): 11.280 (user 9.800, system 1.480), 100% CPU", "Elapsed application CPU time (seconds): 5.162, 46% CPU" ) reportType:CrashLog maxTerminationResistance:Interactive> My questions: 1.) Is there any way to get notified (via Crashlytics, Xcode Organizer, or any other reporting mechanism) when this type of system-level termination happens — similar to how we’re notified of crashes? 2.)Is there any way for a watchOS app to receive runtime warnings from the system when it’s about to exceed CPU or memory limits — similar to UIApplication.didReceiveMemoryWarningNotification on iOS? Thanks in advance!

Speech Recognition Entitlement Not Appearing in App ID Capabilities
Hello, I recently enrolled in the Apple Developer Program and created an App ID with the bundle ID com.echo.eyes.voice. I am trying to enable Speech Recognition in the App ID capabilities list, but the option does not appear — even after waiting over a week since my membership was activated. I’ve already: Confirmed my Apple Developer account is active Checked the Identifiers section in the Developer portal Tried editing the App ID, but Speech Recognition is not listed Contacted both Developer Support and Developer Technical Support (Case #102594089120), but was told to post here for help My app uses Capacitor + the @capacitor-community/speech-recognition plugin. I need the com.apple.developer.speech-recognition entitlement to appear so I can use native voice input in iOS. I would really appreciate help from an Apple engineer or anyone who has faced this issue. Thank you, — Daniel Colyer

NSUbiquitousContainers
I'm using Xcode 16.3 and I want to add the key "NSUbiquitousContainers" but I cannot do it in the Entitlements file, it should be in info.plist file! I have done it before but in previous versions of Xcode when the info.plist was in the project navigator. However, now I cannot find the file and I did not find any way to create it! Please guide me in detail how to proceed (I'm not new to Swift or SwiftUI but not familiar to project settings)?

Provisioning Profile Does Not Include Required Speech Recognition Entitlement
I am building an iOS app with the App ID: com.echo.eyes.app I have a paid Apple Developer membership and have followed all correct procedures, including: Adding com.apple.developer.speech-recognition manually to the App.entitlements file Setting Info.plist keys for microphone and speech permissions Assigning my Apple Developer Team to the project Setting App/App.entitlements under Code Signing Entitlements Despite all this, Xcode automatic signing fails, and I receive the error: vbnet Copy Edit Provisioning profile 'iOS Team Provisioning Profile: com.echo.eyes.app' doesn't include the com.apple.developer.speech-recognition entitlement. I am unable to add the entitlement via the Capabilities section, and no method I try will allow provisioning to succeed. Please update this App ID to include the required entitlement in the provisioning profile. This issue is preventing all voice recognition functionality. Thank you.

Feedback Assistant: „This Feedback will no longer be monitored, and incoming messages will not be reviewed.“
Every now and then I get this very frustrating message on Feedback Assistant. For instance, in FB14696726 I reported an issue with the App Store Connect API. 4 weeks later, I got a reply, asking among other things for a „correlation key and Charles log“. I immediately replied saying that I didn‘t know what those are, and they replied After reviewing your feedback, it is unclear what the exact issue is. I pointed out that I had asked a question which was left unanswered, and they replied explaining what the correlation key is. Then I asked again what the Charles log is. They replied The Apple Developer website provides access to a range of videos covering various topics on using and developing with Apple technologies. You can find these videos on our Development Videos page: http://developer.apple.com/videos. I opened the link and searched for „Charles“ but there were no results, so I asked to kindly point me to the video answering my question. They replied 3 months later (today): Following up on our last message, we believe this issue is either resolved or not reproducible with the information provided and will now consider this report closed internally. This Feedback will no longer be monitored, and incoming messages will not be reviewed. This is not the first time I ask for clarification and get back a message basically telling me that „we won‘t answer any questions you may have and won‘t hear anything you still may have to say about this issue“. They didn‘t even ask me to verify if the issue is resolved or not, like they sometimes do. No, they just shut the door in my face. I just wanted to share this frustrating experience. Perhaps an Apple engineer wants to say something about it or a developer has had a similar experience?

Portal of Apple for tracking health(crashes/hangs)
We are looking for a platform or portal provided by Apple that allows us to track crashes, hangs, or other runtime issues faced by users while using our iOS/macOS application. This is similar to how we currently use Windows Error Reporting (WER) for our Windows application. Important note: Our application is not distributed via the Apple App Store — it is delivered through enterprise distribution or ad-hoc provisioning.

Unexpected performance penalty attributed to first Swift Testing test
I have a Swift package with a test suite that contains some tests implemented with Swift Testing. Locally, they run quickly, but when I run them on Semaphore CI (https://semaphore.io), the first Swift Testing test to execute incurs a performance penalty. I'm running the tests with xcodebuild on iOS Simulator: xcodebuild test \ -scheme "Scheme" \ -workspace Workspace.xcworkspace \ -destination "platform=iOS Simulator,name=iPhone 16,OS=18.2" The scheme is configured to use a test plan that has parallelization disabled. Here's an excerpt from the output showing what I'm seeing: Test Suite 'All tests' started at 2025-04-03 07:47:37.328. ◇ Test run started. ↳ Testing Library Version: 102 (arm64-apple-ios13.0-simulator) ◇ Iteration 1 started. ◇ Suite <redacted> started. ◇ Test foo() started. ✔ Test foo() passed after 23.063 seconds. When foo() is not the first test it runs in under 100 ms. The reason that I have parallelization disabled is that I was initially seeing all of the tests in this suite incur a performance hit. But now it's clear that there must be some startup cost. Things I'm wondering: What is this startup penalty? Why don't I encounter it locally? Why is it attributed to the first test? (this seems like a bug) My wild guesses around 1 so far have been… maybe some simulator clone is booting. I've tried to rule that out by disabling parallelization, but maybe there's still something there. maybe swift testing is getting loaded lazily and there's some kind of dynamic linking cost Thoughts on 2… maybe there's some one-time penalty when using swift testing that I've already incurred locally but that has not yet been incurred in the CI image Guidance welcome! x-posted: FB17102970 (Unexpected performance penalty attributed to first Swift Testing test) https://forums.swift.org/t/first-swifttesting-test-always-slow/79066

Unable to Test Xamarin App with iOS 26 Simulators in Visual Studio
Hello, I’m trying to test a Xamarin.iOS application using the iOS 26 simulators in Mac Visual Studio, but I’m encountering an issue where the simulators are not appearing or accessible from Visual Studio. Details: macOS version: 15.6 (24G84) Xcode version: 26 Beta 5 Visual Studio version: 17.6.0.80 Xamarin.iOS version: Xamarin.Forms (Version: 4.6.0.1180) using XAML for cross-platform support (iOS/Android) The problem started after updating to iOS 26 SDK. I am unable to select or run the app on any iOS 26 simulator from Visual Studio. Has anyone faced a similar issue? Is there any configuration or workaround to enable iOS 26 simulators for Xamarin projects? Thanks in advance for your help.

Unexpected app version in logs — does MARKETING_VERSION change dynamically?
Hello, I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice. We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version. Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3. However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store. In our project, we set the app version using the MARKETING_VERSION environment variable. This value is configured via XcodeGen, and we define it in a YAML file. Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected. We'd like to know what might cause this behavior, and if there are any known factors that could lead to this. Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store? yaml: info.plist:

Lost X Code Project for a Live Application
Hello, I currently have a live application in the iOS App Store that needs an update to start functioning again, but I've lost the source code in a hard drive failure. Is there a way to reverse engineer the currently deployed package that is live (and also a way to download it from App Store Connect)⁉️ The development change itself is just a very small change for an API route in the code itself. I could even direct an engineer at Apple to make the change in 5 minutes! Let me know if this is possible. Thanks❗️

App crashes on start in TestFlight
Hi, I have a .NET MAUI app running on .NET 9. When I test locally in debug or release mode it works perfectly fine, but when testing from TestFlight it crashes almost immediately every time. I have sent the crash report to TestFlight and produced the symbolicated.crash file (attached), but I'm not sure it's helpful for understanding how to fix the issue. If anyone can help me understand what the issue might be and any possible fixes it'd be very much appreciated. I'm developing using Visual Studio 2022 paired to my Mac. I have distributed previously without issue, but now can't seem to, even after reverting recent code. net9.0-ios 15.0 symbolicated.crash

Feedback Assistant: „This Feedback will no longer be monitored, and incoming messages will not be reviewed.“
Every now and then I get this very frustrating message on Feedback Assistant. For instance, in FB14696726 I reported an issue with the App Store Connect API. 4 weeks later, I got a reply, asking among other things for a „correlation key and Charles log“. I immediately replied saying that I didn‘t know what those are, and they replied After reviewing your feedback, it is unclear what the exact issue is. I pointed out that I had asked a question which was left unanswered, and they replied explaining what the correlation key is. Then I asked again what the Charles log is. They replied The Apple Developer website provides access to a range of videos covering various topics on using and developing with Apple technologies. You can find these videos on our Development Videos page: http://developer.apple.com/videos. I opened the link and searched for „Charles“ but there were no results, so I asked to kindly point me to the video answering my question. They replied 3 months later (today): Following up on our last message, we believe this issue is either resolved or not reproducible with the information provided and will now consider this report closed internally. This Feedback will no longer be monitored, and incoming messages will not be reviewed. This is not the first time I ask for clarification and get back a message basically telling me that „we won‘t answer any questions you may have and won‘t hear anything you still may have to say about this issue“. They didn‘t even ask me to verify if the issue is resolved or not, like they sometimes do. No, they just shut the door in my face. I just wanted to share this frustrating experience. Perhaps an Apple engineer wants to say something about it or a developer has had a similar experience?

I've tried to rule that out by disabling parallelization, but maybe there's still something there. maybe swift testing is getting loaded lazily and there's some kind of dynamic linking cost Thoughts on 2… maybe there's some one-time penalty when using swift testing that I've already incurred locally but that has not yet been incurred in the CI image Guidance welcome! x-posted: FB17102970 (Unexpected performance penalty attributed to first Swift Testing test) https://forums.swift.org/t/first-swifttesting-test-always-slow/79066

Unable to Test Xamarin App with iOS 26 Simulators in Visual Studio
Hello, I’m trying to test a Xamarin.iOS application using the iOS 26 simulators in Mac Visual Studio, but I’m encountering an issue where the simulators are not appearing or accessible from Visual Studio. Details: macOS version: 15.6 (24G84) Xcode version: 26 Beta 5 Visual Studio version: 17.6.0.80 Xamarin.iOS version: Xamarin.Forms (Version: 4.6.0.1180) using XAML for cross-platform support (iOS/Android) The problem started after updating to iOS 26 SDK. I am unable to select or run the app on any iOS 26 simulator from Visual Studio. Has anyone faced a similar issue? Is there any configuration or workaround to enable iOS 26 simulators for Xamarin projects? Thanks in advance for your help.

Unexpected app version in logs — does MARKETING_VERSION change dynamically?
Hello, I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice. We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version. Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3. However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store. In our project, we set the app version using the MARKETING_VERSION environment variable. This value is configured via XcodeGen, and we define it in a YAML file. Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected. We'd like to know what might cause this behavior, and if there are any known factors that could lead to this. Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store? yaml: info.plist:

Lost X Code Project for a Live Application
Hello, I currently have a live application in the iOS App Store that needs an update to start functioning again, but I've lost the source code in a hard drive failure. Is there a way to reverse engineer the currently deployed package that is live (and also a way to download it from App Store Connect)⁉️ The development change itself is just a very small change for an API route in the code itself. I could even direct an engineer at Apple to make the change in 5 minutes! Let me know if this is possible. Thanks❗️

App crashes on start in TestFlight
Hi, I have a .NET MAUI app running on .NET 9. When I test locally in debug or release mode it works perfectly fine, but when testing from TestFlight it crashes almost immediately every time. I have sent the crash report to TestFlight and produced the symbolicated.crash file (attached), but I'm not sure it's helpful for understanding how to fix the issue. If anyone can help me understand what the issue might be and any possible fixes it'd be very much appreciated. I'm developing using Visual Studio 2022 paired to my Mac. I have distributed previously without issue, but now can't seem to, even after reverting recent code. net9.0-ios 15.0 symbolicated.crash

Cannot compile a simple C++ program on Mac OS
I'm trying to compile a simple hello world C++ program on my MacBook Pro. I have a M3 Pro (Nov 2023) running Sequoia 15.6. The program is: #include &lt;iostream&gt; int main() { std::cout &lt;&lt; "Hello World!"; return 0; } The error I get is: In file included from test.cpp:1: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/iostream:42: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/ios:220: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/__locale:15: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/__memory/shared_ptr.h:13: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/__compare/compare_three_way.h:13: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/__compare/three_way_comparable.h:12: In file included from /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/__compare/common_comparison_category.h:15: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/cstddef:42:5: error: &lt;cstddef&gt; tried including &lt;stddef.h&gt; but didn't find libc++'s &lt;stddef.h&gt; header. This usually means that your header search paths are not configured properly. The header search paths should contain the C++ Standard Library headers before any C Standard Library, and you are probably using compiler flags that make that not be the case. 42 | # error &lt;cstddef&gt; tried including &lt;stddef.h&gt; but didn't find libc++'s &lt;stddef.h&gt; header. \ | ^ However, I can see stddef.h in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/v1/ and in /usr/local/include
