I have an application made from Flutter, which is possible to run on VisionOS by running as design to Ipad, and I would like that inside this application would be possible to go to mixed reality somehow. I am trying to do so far was to embedded the vision project that I have inside the swift application that flutter generates, but in this attempt I got an error from Xcode telling me that this way is not possible. I wonder if is there an another way that I could achieve my goal?

We use XCode 15.2 to build our application, but we found that the app crashes on iOS 12.1.1, while it works without crashing on iOS 12.5.7. We discovered that the crash is related to ImageLoaderMachO::doModInitFunctions. We're not sure what is causing this.

Hi everyone, I recently developed a Chess engine in C using Xcode on my old Mac. After purchasing a new Mac, I attempted to run my project but encountered the following error: dyld[12498]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed dyld[12498]: Library not loaded: /usr/lib/libSystem.B.dylib Referenced from: <7D3E4140-BCEC-3C04-8C77-11EB7AEEB393> /Users/simonmizrahi/Library/Developer/Xcode/DerivedData/Chesspresso_Take_2-awdtkeshpaucukgespypcbgxgsvy/Build/Products/Debug/Chesspresso Take 2 Reason: tried: '/Users/simonmizrahi/Library/Developer/Xcode/DerivedData/Chesspresso_Take_2-awdtkeshpaucukgespypcbgxgsvy/Build/Products/Debug/libSystem.B.dylib' (no such file), '/usr/lib/system/introspection/libSystem.B.dylib' (no such file, no dyld cache), '/usr/lib/libSystem.B.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/libSystem.B.dylib' (no such file), '/usr/lib/libSystem.B.dylib' (no such file, no dyld cache)' I’ve reinstalled macOS and Xcode, but the issue persists. I’ve verified that libSystem.B.dylib is missing from /usr/lib/. I am quite anxious to find a solution, as I’ve read similar posts but do not understand how to fix the problem in my specific case. Could anyone provide guidance on how to resolve this and get my project running on my new Mac? Thanks in advance for your help!

Hi, I am writing my own little toy programming language and when I try to link the binary object file (.o file) it requires a _main symbol. I wonder if there is a way to exclude this, presumably, a C runtime requirement? Is it safe to provide a stub _main symbol, or provide a the _main as the entry point to my own little runtime? What is the correct way to invoke the linker with the appropriate flags?

Hi there, I have just recently had a go at trying to build an app using unreal engine. After much difficulty of finally getting the app to sign, build and deploy I am having issues with the app crashing immediately after opening it. I have had a look at the crash log to find it including EXC_BAD_ACCESS (SIGSEGV) which I've come to understand means it may be accessing a value that doesn't exist. I was unable to understand or figure out any of the rest of it to find any clues on how to solve my issue. If anyone could point me in the right direction as to why the app is crashing, it would be greatly appreciated. crash log

I maintain a library that has thus far used Cocoapods to manage dependencies and also distribute an xcframework of the library. I'd now like to also distribute the same library through Swift Packages but am running into issues. I'm using the same xcframework in a local Swift Package and have added all the necessary dependencies to Package.swift, but when I attempt to add this Swift Package to a test app, the app will build correctly but fail at runtime due to a missing .framework file for a dependency I'll just call THE_DEPENDENCY: dyld[61483]: Library not loaded: @rpath/THE_DEPENDENCY.framework/THE_DEPENDENCY Referenced from: <75074516-C1CD-3251-8807-94A7502176A7> /Users/ME/Library/Developer/Xcode/DerivedData/MY_TEST_APP-bwfsfwjjnagdurdnjrhhdppgitvr/Build/Products/Debug-appletvsimulator/MY_LIBRARY.framework/MY_LIBRARY Reason: tried: '/Users/ME/Library/Developer/Xcode/DerivedData/MY_TEST_APP-bwfsfwjjnagdurdnjrhhdppgitvr/Build/Products/Debug-appletvsimulator/THE_DEPENDENCY.framework/THE_DEPENDENCY' (no such file) Indeed, there is no THE_DEPENDENCY.framework file anywhere, it is only present in a version of the test app that uses Cocoapods. As you can see, the reference to this file arises from MY_LIBRARY, and in MY_LIBRARY.xcodeproj I can see there is a reference to THE_DEPENDENCY.framework, which appears as a consequence of running pod install. Thus, it looks to me like the .framework file appears either as part of Cocoapods dependency injection, or perhaps as a consequence of how that dependency is distributed through Cocoapods. I'm forced to install pods during my build process because, as I understand it, all dependencies must be available during the archiving process to avoid compilation errors. If the dependencies must be available during archiving, but adding the dependencies via Cocoapods creates a reference to .framework files that will not be present in a Swift Package project, what is the best practice for distributing xcframework binaries to both Cocoapods and Swift Package Manager? It looks as though I'll have to build two different xcframeworks: one built with dependencies provided via pods, and the other via swift packages. Is this correct?

Hello, I have a problem with an iOS app that is deployed via the MDM system Intune. The app closes immediately after starting. The APP works without distribution via the MDM. Devices with iOS 17 also work. I am attaching a crash report. (txt is ips) Unfortunately I have no idea how to solve the problem because it only occurs via the MDM and therefore I cannot debug it. The problem occurs in production environment. Please help me with the solution. Insight Mobile-2024-06-24-144828.txt Best regards Moritz

I have an iOS app target with a framework dependency and want to merge that framework by setting MERGED_BINARY_TYPE to automatic in the app target's build settings. It all works fine until I add a (non-private) UIHostingController to the framework target. When I do this it crashes on startup with this message: dyld[15894]: Symbol not found: _OBJC_CLASS_$__TtC5Frame4MyVC. Xcode 15.1b3 Reported as bug via Feedback Assistant: FB13379276

Hi! I've been dealing with mergeable libraries quite some time. However I can't achieve the following scenario: I have 2 xcframeworks A and B that are merged as part of a third xcframework called C. And my app needs to import something from A and B. As per the documentation we have to remove the references from A and B from the final app and replace it with C. If I work on the same xcodepoj it works like a charm (maybe because of caches), but if I try to compile C as a separate XCFramework and distribute it as a packed library, the app is not able to resolve the symbols to A and B classes. This C xcframework is compiled with BUILD_LIBRARY_FOR_DISTRIBUTION se to true and if I check its swiftinterface files it is not declaring the symbols from A and B. However the size of the binary seems to have A and B. Is there any way to export A and B symbols as part of C's swiftinterface? If I add @_exported, it is forcing me to declare the import of A and B wherever I use them and therefore I'm going to have duplicated symbols Thanks!

I'm working on a macOS app. Due to security requirement, I add the following line in XCode other linker flags: -Wl,-sectcreate,__RESTRICT,__restrict,/dev/null But after testing, we found that app crashed at launch if system integrity protection disabled. Here is the report: System Integrity Protection: disabled Crashed Thread: 0 Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace DYLD, Code 1 Library missing Library not loaded: @rpath/MyLib.framework/Versions/A/MyLib Referenced from: <845E83E4-9526-36F0-8A2D-ADD407697F4D> /Applications/MyApp/MyApp.app/Contents/MacOS/MyApp Reason: tried: '/System/Library/Frameworks/MyLib.framework/Versions/A/MyLib' (no such file, not in dyld cache), (security policy does not allow @ path expansion) (terminated at launch; ignore backtrace) Thread 0 Crashed: 0 dyld 0x185f3a55c __abort_with_payload + 8 1 dyld 0x185f46b10 abort_with_payload_wrapper_internal + 104 2 dyld 0x185f46b44 abort_with_payload + 16 3 dyld 0x185ecd584 dyld4::halt(char const*, dyld4::StructuredError const*) + 304 4 dyld 0x185eca254 dyld4::prepare(dyld4::APIs&, dyld3::MachOAnalyzer const*) + 3884 5 dyld 0x185ec8edc start + 1844 Looks like dyld can't load rpath if restrict segment exist & SIP disabled. Is there a way to fix it? The framework & dylib files needs to be in the bundle to avoid other app using them, so point to /usr/lib is not an option. Thanks.

Hi there, My app detects connected BlackMagic devices on a user's machine and this is done using the DeckLink SDK which first tries to load /Library/Frameworks/DeckLinkAPI.framework using CFBundleCreate. I have not been able to create a notarized app which successfully detects the devices. Either the DeckLinkAPI works or the app starts up without showing "the developer cannot be verified" on my test computer but never both. This is what I've tried so far: signed app: DeckLinkAPI available hardened runtime: DeckLinkAPI not available hardened runtime + com.apple.security.cs.disable-library-validation: DeckLinkAPI available, notarization succeeds yet the "the developer cannot be verified" I've also tried to use weak linking to DeckLinkAPI.framework instead of including the SDK's CFBundleCreate code but that made no difference: I still needed the com.apple.security.cs.disable-library-validation entitlement for that to work which caused "the developer cannot be verified". DeckLinkAPI.framework is notarized: > codesign --test-requirement="=notarized" --verify --verbose /Library/Frameworks/DeckLinkAPI.framework /Library/Frameworks/DeckLinkAPI.framework: valid on disk /Library/Frameworks/DeckLinkAPI.framework: satisfies its Designated Requirement /Library/Frameworks/DeckLinkAPI.framework: explicit requirement satisfied Is there any way to successfully notarize an app to use the DeckLink SDK or any other thirdparty notarized framework which is distributed seperately?

Looking for anyone that has some experience in getting Xcode to work with external compiler/linkers in what is tantamount to a foreign tool chain to build non-apple platform executables. For example, I want to ultimately use Xcode to edit, build, and push bare metal firmware (read "no operating system at external device"). Think of it as in how to use Xcode to develop the firmware in the processor in the ThunderBolt 4 cable (TPS65994AD) which runs a variant of the ARM Cortex-M machine code. Suppose I don't want to use TI's "Code Composer Studio (CCS)" but instead want to use Xcode which might drive some part of Code Composer Studio. Xcode supports external / foreign tool chains (or did) but the question is "have you done it successfully for any foreign platform?" and if so what was your approach? I'm trying to not waste a bunch of time with horrendous make file scripting only to find out that I did not have to do it or it headed down the wrong directions. I have a hard time believing that someone hasn't done this before for something even more monolithic like Arduino.

The following program demonstrates the issue. It prints: y = 2.000000 CGRectMake symbol not found What would cause the symbol not to be found when using the dlopen/dlsym functions? #import <CoreGraphics/CoreGraphics.h> #import <dlfcn.h> int main(int argc, const char * argv[]) { CGRect rect = CGRectMake(1.0, 2.0, 3.0, 4.0); printf("y = %f\n", rect.origin.y); void * handle = dlopen("/System/Library/Frameworks/CoreGraphics.framework/Versions/A/CoreGraphics", RTLD_LAZY); if (handle == NULL) { printf("handle == NULL\n"); } else if (dlsym(handle, "CGRectMake") == NULL) { printf("CGRectMake symbol not found\n"); } return 0; } I am observing this issue with other symbols as well. What is special about them?

Assuming I have a static library where all global symbols need to be re-exported by the target executable. How do I extract these symbols into a file to be used with ld's -exported_symbols_list and Xcode's EXPORTED_SYMBOLS_FILE? I was thinking about nm -gUjo … + sed but maybe there is abetter way?
