I have a shell script that turns a framework into a plain dylib and updates some dependent library paths using install_name_tool. It works, but if the framework was signed, I get warnings like:
install_name_tool: warning: changes being made to the file will invalidate the code signature in: [redacted].dylib (for architecture x86_64)
I thought I could get rid of the warning by adding
codesign --remove-signature dylib-path
to the script before using install_name_tool, but then I get errors like
install_name_tool: fatal error: file not in an order that can be processed (link edit information does not fill the __LINKEDIT segment): [redacted].dylib (for architecture x86_64)
Is there a way to fix this?

My app has a pod dependency (xcframework), BUILD_LIBRARY_FOR_DISTRIBUTION was changed to YES when generating the xcframework.
After adding the pod dependency in the Podfile the app crash:
dyld[21474]: Symbol not found: _$s10Foundation13URLComponentsV3urlAA3URLVSgvg
Referenced from: /Users/user_repo/Library/Developer/CoreSimulator/Devices/.../data/Containers/Bundle/Application/.../MyApp.app/Frameworks/PodDependency.framework/PodDependency
Expected in: /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 15.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/Foundation.framework/Foundation
The app is build on XCode15.2 and don't crash on iOS16+. Cocoapods version: 1.15.2
I already tried to set BUILD_LIBRARY_FOR_DISTRIBUTION to YES for the specific pod in the Podfile of my project.
environment: Apple clang version 14.0.3 (clang-1403.0.22.14.1)
I am trying to override c++ symbols at linking time for the purpose of inserting measurement code into an existing library.
Perhaps typical linkers would search for symbols in specifing order of library and adopt the first hit.
Xcode's ld apparently does this in units of a object file.
If you create one object file to override one function and link it first, but call another function in the same object file contained in the original library, that one will be adopted. As a result, you cannot override function.
To override a function, the function to be overridden must be moved to a new cpp file and separated from the object file.
Here is a sample program to test this.
https://onedrive.live.com/redir?resid=DD46698E2D493F32!395&authkey=!AJqfiva7CXIDI_Y&e=OaFlSr
As you can see in main.cpp, func() and bar() are called from main().
func() and bar() are implemented in func.cpp and bar.cpp, respectively.
They are linked to libTest.lib.
To override func(), link libTest2.lib implementing func2() in func2.cpp, before libTest.lib.
If you run make and look at the code with objdump -d a.out, you can see the override.
Because the content of func2() is return i+1, __Z4funci contains leal 1(%rdi), %eax.
Then, build with make clean and make CONCAT=1, func() and bar() are concatenated into one cpp file and compiled.
The generated a.out is checked in the same way, you will see movl %edi, %eax at same position which means return i; which is the content of func().
This sample is small in scale, but in a larger project, it can be quite a hassle to isolate the functions you want to override.
Is there any easier way to override the function?
Since the original function name cannot be changed, it is our policy not to use -alias symbol_name alternate_symbol_name.
Thanks.
I am currently experiencing a problem with Xcode where I am unable to view the verbose output of the linker, despite having set the -v flag in my build settings. When attempting to build my project, I encounter a "Linker command failed with exit code 1" error, along with a message about "Undefined symbols". The specific issues that arise are:
After setting the -v flag for more verbose logging, the expected detailed output is not visible in the Report Navigator within Xcode.
When I right-click on the error in the Issue Navigator and select "Reveal in Log," there is no response from Xcode and the log does not appear.
Troubleshooting steps I've taken so far:
Ensured that the -v flag is correctly set in the "Other Linker Flags" section of my build settings.
Tried cleaning the build folder and deleting Derived Data.
Attempted to manually expand the error in the Report Navigator to access the detailed logs without success.
Restarted Xcode
Environment:
Xcode version: 15.2 (15C500b)
Target device: iPhone 15 Pro (17.2)
macOS version: Sonoma 14.0 (23A344)
I'm looking for assistance in resolving this issue so that I can access the detailed linker logs and address the "Undefined symbols" error. Any guidance on how to enable verbose output for the linker or alternative methods to retrieve this information would be greatly appreciated.
I am using
Xcode version 13.0 beta
Unity Version 2022.3.8.f1
After solving the semantic errors I am now getting 100 different errors
Link UnityFramework (arm64)

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 have an Xcode project with an obj-c .c file and a .h file aswell as a .swift file where I am calling functions from those obj-c files with a bridging header but when I build my project I get a duplicate symbols error and Xcode doesn't show where.
here is .h header file:
#define smc_h
#include <stdint.h>
#include <mach/mach.h>

Hello, while my project, which I created with the Unity game engine, runs smoothly in the editor, when I try to run it and/or archive through Xcode, I receive the following error:
Undefined symbols:

When I right click on the problem and click Reveal in log it doesn't take me anywhere.
Can you help me with this?
Thanks.
I have an Xcode project that include a .c file and .h header file. I am getting a duplicate symbol error and I cannot pinpoint what part of my code is the issue or maybe if it's a configuration issue in my Xcode settings or not.

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.
Can you help me?

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).

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?

My team is building an SDK to release to game developers. Does our SDK require to meet the same IOS App store submission checklist? Wondering if there is any SDK checklist for IOS
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.
Hi,
I wanted to compile a project (For the compilation I used gcc-13 from home-brew) and I got the following error from the linker:

I am using a MacBook Pro M2 (Ventura 13.5.2 (22G91)) and the CommandLineTools version 15.0. I have read through some earlier posts about linker issues, which were solved by downgrading Xcode. After downgrading to 14.3.0 I was able to compile the code. Did anyone run into the same Problem? If so, is there a better solution for this?
Best regards
