Recently Apple deprecated the NXFindBestFatArch, used to find the most compatible / appropriate slice in a universal/fat binary. However its replacement macho_best_slice is broken and will return EBADARCH for any non-Apple binary 😓 The issue seems to be that the dyld3::GradedArchs::grade method does not take into the account the nuances of the CPU sub types of type *_ALL. Namely that any CPU with a more specific sub type (e.g. CPU_SUBTYPE_ARM64E) can also still execute code compiled with a CPU sub type of *_ALL (e.g. CPU_SUBTYPE_ARM64_ALL). All the details (+code, +debugging, +disassembly) posted at: https://objective-see.org/blog/blog_0x80.html. Also, hrmm!?:

I am recently migrated from android to Apple Store. Trying to publish my first Unity Game but this error pop up. Would be great if anyone could help. I think this bug belongs to Admob on Unity Game.

I am now using the fortran compiler to compile the codes with the command of "make -f Makefile". In the previous time, the command: make -f Makefile works well, but after updating the MacOS system, the same command results in the following error: -macosx_version_min has been renamed to -macos_version_min ld: unknown options: -commons collect2: error：ld returns 1 Is there anyone know how to solve the above problem? Thanks a lot for your time and help.

Hello, I have been experiencing the problem you see below for a long time. How can I solve it? As a result of my research, I tried many things but it didn't work. Cocoapods is used in the project.

Hello, I'm facing a crash on launch for my program. This has been a recent find since upgrading to Xcode 15.1 and using new ld_prime linker. I am able to launch my release build which has different optimization flags. I'm not using any Diagnostics options in my program scheme. The error I get is about a system framework not being found. When I look up these file locations the framework found in System/Library is there but the one in /private/preboot/Cryptexes/OS is missing. I'm running with --verbose linker/build flags but I don't get any more info than this (no warnings during build either). dyld[439]: Library not loaded: /System/Library/Frameworks/Foundation.framework/Foundation Referenced from: <XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX> /private/var/containers/Bundle/Application/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/application.app/application Reason: tried: '/System/Library/Frameworks/Foundation.framework/Foundation' (no such file), '/private/preboot/Cryptexes/OS/System/Library/Frameworks/Foundation.framework/Foundation' (no such file), '/System/Library/Frameworks/Foundation.framework/Foundation' (no such file, no dyld cache) These look like system files so I would appreciate some assistance in finding why the framework in the Cryptexes directory is missing. Thank you!

I'm struggling with compiling lib opus so that it works in the simulator on Apple silicon. I found a thread on the forums that seems to address part of the issue, but I am unable to build the static lib so that it shows the platform it is targeting. The thread mentions that I should be able to run otool and see a "load commands" that indicate the platform. When I run otool against the static library that we have created, it doesn't list any load commands. I don't see LC_BUILD_VERSION or LC_VERSION_MIN_***. Why would there not be any "Load command" entries? % otool -l -arch arm64 dependencies/lib/libopus.a Archive : dependencies/lib/libopus.a dependencies/lib/libopus.a(bands.o): is an LLVM bit-code file dependencies/lib/libopus.a(celt.o): is an LLVM bit-code file dependencies/lib/libopus.a(celt_encoder.o): is an LLVM bit-code file dependencies/lib/libopus.a(celt_decoder.o): is an LLVM bit-code file ... dependencies/lib/libopus.a(mlp.o): is an LLVM bit-code file dependencies/lib/libopus.a(mlp_data.o): is an LLVM bit-code file The static library has the two architectures embedded in it, but when compiling the framework for the simulator platform the linking phase complains that we are building for the simulator, but linking object code built for ios. % lipo -info dependencies/lib/libopus.a Architectures in the fat file: dependencies/lib/libopus.a are: x86_64 arm64 In case you are curious, I'm just piggybacking on this project that has a build-libopus.sh script in the root directory that builds the official open source Opus library files. My hope is to build this static library for ios, ios-simulator, and mac-catalyst platforms and then include them in a xcframework.

I have a demo app to explain how mergeable libraries work and I am stuck when archiving. I have: Project Demo App Target Framework A Framework B External Framework Project C (sub-project to Project Demo) Framework C I have all three frameworks in the demo project's dependencies, linking and embedding. Implicitly find dependencies is OFF (because that is how the actual app I will be applying this to is built) I can build to sim/device for Debug and for Release. It all works. I can find my embedded resources. I have checked the binaries with otool -l and I can see where frameworks are loaded in Debug but not in Release. Yay! But when I Archive the app, I get an error only for my External framework (not in the same project as the app) that it cannot find the file ExternalC.framework/ExternalC, even though if I copy the path, the file exists. Build input file cannot be found: '/Users/MYUSER/Library/Developer/Xcode/DerivedData/MergeableLibrariesDemo-afgemdngqmoznfhczuxrqzkeulhb/Build/Intermediates.noindex/ArchiveIntermediates/MergableLibraries/BuildProductsPath/Release-iphoneos/ExternalC.framework/ExternalC'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it? (in target 'MergeableLibrariesDemo' from project Here are the linker commands for the three frameworks: -Xlinker -merge_library -Xlinker /Users/MYUSER/Library/Developer/Xcode/DerivedData/MergeableLibrariesDemo-afgemdngqmoznfhczuxrqzkeulhb/Build/Intermediates.noindex/ArchiveIntermediates/MergableLibraries/BuildProductsPath/Release-iphoneos/ExternalC.framework/ExternalC -Xlinker -merge_framework -Xlinker SameProjectA -Xlinker -merge_framework -Xlinker SameProjectB Oh ExternalC.framework is an alias to the framework in the Uninstalled Products path This is only an issue if ExternalC has this set: //:configuration = Debug MERGEABLE_LIBRARY = YES //:configuration = Release MERGEABLE_LIBRARY = YES //:completeSettings = some MERGEABLE_LIBRARY Any clues as to what I might have misconfigured?

I have a class category declared and compiled in a mac os static lib: #import <Foundation/Foundation.h> @interface NSNumber(MyExtension) -(NSString *)CallMe; @end then this staticLib is added to a mac console app in XCode and used: #import <Foundation/Foundation.h> #import "MacStaticLib.h" int main(int argc, const char * argv[]) { @autoreleasepool { NSNumber *one = [NSNumber numberWithInt:12]; NSLog(@"%@",[one CallMe]); } return 0; } Compiles fine but fails in runtime, unrecognized selector 'CallMe' send to instance... what's wrong or what I missed? Thanks!!

I am using iTerm2 on M1 Macbook pro. I wrote an assembly source code and want to execute the code. but I don't know what kind of commands I have to use for it. and I don't wanna get the command only. I wanna know what the command means too.

I am upgrading the react-native from 71 to 73. Once Ios is built successfully and its been installed on the simulator, its throwing an error "Command Ld emitted errors but did not return a nonzero exit code to indicate failure". I did the following trying to resolve it but nothing worked so far. deleted derived data pod deintegrate pod install clean project Any help is appreciated.

We have one custom library/framework with ARCHS = $(ARCHS_STANDARD) under build settings. I export the library/framework with "Any iOS device" target and export the library/framework. But when we try to integrate this custom library/framework in to another project ( M1 with xcode 14.2 with rosetta enabled ) its not running in iOS simulator. Getting error like. : Unsupported Swift architecture Note : Its running fine in real device.

I'm trying to build a dynamic version of an old C static library. The static library, as it stands, references symbols which are defined in the program the static library is bound to. When I try to build this as a dynamic library I get: ld: symbol(s) not found for architecture x86_64 messages. I suspect there is a way to work around this (weak references?) but I don't understand how to do it, and none of the online documentation and commentary I have found seems to help. Does anyone have suggestions to offer?

I'm using the official Dropbox Objective C framework within an Xcode Objective C iOS project. If I clean and rebuild the project, I have no problems running the app. If I then rebuild and run, I get a linker error: dyld[12193]: Symbol not found: _OBJC_CLASS_$_DBScopeRequest Referenced from: <A3ABDE7A-6441-3771-9061-F2CC46FEEBF3> /private/var/containers/Bundle/Application/30EC2350-4AE3-4194-9F0C-B5087FEDB042/AppName.app/AppName Expected in: <163AA2D6-A97B-396E-8300-E44FA89645D8> /private/var/containers/Bundle/Application/30EC2350-4AE3-4194-9F0C-B5087FEDB042/AppName.app/Frameworks/ObjectiveDropboxOfficial.framework/ObjectiveDropboxOfficial I can then clean and build and run again successfully. So it sort of works, but having to clean and build every single time is very inefficient. It doesn't seem to be a problem inherent to the Dropbox framework. I've tried the usual debugging steps such as deleting the derived data folder, restarting Xcode, etc.
