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 <iostream> int main() { std::cout << "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: <cstddef> tried including <stddef.h> but didn't find libc++'s <stddef.h> header.

I'm running macOS 15.5. I now have Xcode 26 and I'm testing my iOS app against iOS 26. I've encountered several UIKit / iOS 26 bugs I'd like to report. In Feedback Assistant I choose "Developer Technologies & SDKs". Eventually I get asked "What build does the issue occur on?". The list of choices is: iOS 18.2 Seed 4 iOS 18.1.1 iOS 17.7.2 An earlier iOS build I'm not sure So how to I report this as an iOS 26 beta 1 issue?

I noticed that there are numerous missing source repositories. For instance: https://github.com/apple-oss-distributions/IOHIDFamily/blob/07b14847cb5b4e0f826a3970961624969e443a6e/IOHIDFamily.xcodeproj/project.pbxproj#L4274 Many files referenced in the xcodeproj are listed but do not actually exist in the repositories.

(Copy pasted from FB17261080 that I submitted) Hi: Apple's SDK (libSystem.B.tbd) provides definition for multiple symbols(__unw_add_dynamic_fde / __unw_add_find_dynamic_unwind_sections ), but doesn't provide corresponding headers, available in LLVM upstream as libunwind_ext.h We need such headers to write Exception-Enabled JIT Framework for macOS

Hi, This can't be right. Is there really no replacement for Quartz Debug?!? As the sole developer on a project who has an Intel Mac and Quartz Debug, I am basically a god now. Everyone else has Apple Silicon and... I think they're randomly guessing at this point. Because I have entire teams sending me Intel Mac builds of stuff just so I can test it in QD. This is THE TOOL we used at NewTek to find performance issues, and THE TOOL I used for a dozen companies after that, to help them with similar issues. If there's no replacement, is there a reason there's no replacement? This feels like a massive step backwards, having to guess at problems like this. -Chilton

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.

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!

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

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)?

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!

I use CMake for my builds not the XCode GUI. I want to be able to build a single .app that contains both the GUI version and the command line version. I have seen products that ship both as part of the same .app (e.g. CMake) so this is clearly entirely possible, the 64k question is HOW? Right now I am building them as separate apps - lets call them DSS and DSSCL (*). The code base for each is in its own directory - each with its own CMakelists.txt file. My initial thoughts are to change the build for DSSCL so it doesn't create a bundle and then simply copy the DSSCL command and related .qm files into DSS.app/.../MacOS. However that's likely enough totally wrong, so how should I handle this please. As much detail as possible please, I am very new to macOS development -please don't assume knowledge of stuff that's second nature to you Many thanks David (*) Strictly they are DeepSkyStacker and DeepSkyStackerCL

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

About three weeks ago I submitted a DTS ticket (13097367) to receive code level support with a potential SwiftUI bug. At first I did not receive any response at all (beside the automatic confirmation that the ticket has been created). Only after posting the question here, I got a reply from a DTS engineer. However, the proposed solution did not really solve the problem but only circumvents it (UI freezes when ScrollView reaches below SafeArea. Solution: Do not use ScrollView below SafeArea...) I pointed out, that this does not really help me. Since then I did not receive any further response. Is this normal? Is there something wrong with my ticket? Maybe it was closed by accident or something? Thank you very much!

I am working on a MAUI application. When I go to archive my build to then release it, my bundle is not including the Assets.car file that apple is seemingly expecting for handling the app icons, which is leading to issues trying to publish my app. The assets are in a AppIcon.appiconset folder in my project (under Platforms>iOS>Resources) with a proper Contents.json file also in there. They are setup as a BundledResource (also have tried ImageAssets for the build type but with the same issue occurring). I am using visual studio 2022 on Windows 11 paired with a Mac (Sequoia 15.5) and Xcode 16.4. I have even tried manually compiling the asset catalog from xcode16.4 and trying to use terminal commands to have actool create the Assets.car but that runs with no files created to the output destination as well as no errors. I believe there may be an issue with actools in my Xcode copy. I have tried uninstalling and reinstalling with no luck. Any suggestions or tips?

I am submitting new App for review and it is rejected due to Crash on iPad Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000000 I am not able to reproduce the same locally, have tested app against same iOS and all the device type but no crash. Can someone help provide some pointers on how to debug/investigate the issue. Attached is the crash report I received: crashlog-C2489824-B949-47D8-BE2B-9D54CAE8F733.ips

I have uploaded my app to App Store Connect TestFlight. Then I have downloaded it in TestFlight on my iPad. But the app always crashes a few seconds after opening. It seems to be always the same issue. I have a few crash reports in App Store Connect--&gt;App name--&gt;TestFlight--&gt;Feedback--&gt;Crashs. I have opened a crash report in Xcode but I don´t find the error that causes the crash. How can I find the error in Xcode? Is it possible to find the class and line in the class where the crash happened? In addition, how can I export a crash report from Xcode? The crash doesn´t happen in debug mode on my iPad, it only happens when I install and open my app after downloading it from TestFlight on my iPad.

Hi there I've recently had my upload rejected in Xcode Organizer as a result of one of the frameworks we use containing bitcode. Error: [ContentDelivery.Uploader.XXXXXXXXXX] Validation failed (409) Invalid Executable. The executable 'Sam.app/Frameworks/Foo.framework/Foo' contains bitcode. Is there an accurate way to determine whether an .xcframework contains bitcode ahead of time without using Xcode Organiser? My current methodology is below, please can I get some confirmation that this is accurate, or suggest a more efficient approach? I have concerns about my approach and whether it throws false positives for empty bitcode markers. 1. get original framework size 2. run xcrun bitcode_strip -r framework_path -o temp 3. get new framework size 4. if new size is smaller than original, then it contains bitcode Thanks for the help, Sam

I would like to inquire about a concern related to the app review process. Specifically, I would like to understand if forcefully denying an application's execution on the iOS Simulator (for instance, by implementing a check in the code that prevents the app from running in a simulated environment) could negatively impact or delay the app’s approval during the App Store review process. This measure is intended solely for security and integrity reasons during development and distribution. The app functions normally on real devices, and all other guidelines and requirements outlined by Apple are being strictly followed. Could you please confirm whether such a restriction on the Simulator is acceptable, and if there are any best practices or recommendations from Apple regarding this? Thank you for your support, and I look forward to your guidance.

Hello, In my IOS app, I have been working on implementing a third-party library's xcframework into my app. (They don't provide spm or cocoapods). However, whenever I import the XCFramework into my app, the build is successful, but when uploading to App Store Connect, I receive an email with an error stating the Swift Support folder is missing. This app was made using SwiftUI. I have a sample project linked below. Other apps also use this framework, so I'm not sure where I'm going wrong. Project

I developed (with AI help) using Xcode an app for myself. It logged certain places visited on a list, with photos and notes. It worked, but after a few days my iPhone can't launch it. What do I have to do to get this to last? I didn't think I needed to pay as this is purely for me.
