Hello yasirkula,

I am facing following issue with the plugin in xcode on mac m1. Please help me with this if you can.

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

When I had exported project from unity, AssetLibrary were not automatically added in other linker flags, so I did it manually. I don't know what may be causing this.
Please help.

This is Photos framework missing rather than AssetsLibrary.

Ok, thanks, I have managed to trace this issue. But I think these frameworks should have been added automatically when building from unity. anyway I have added them manually and it is working now.

[yasirkula]

Yes they should've been. Another plugin might be overwriting Other Linker Flags instead of appending to it.

Actually when I am exporting xcode project, it not generating any other linker flags. all flags I have to add manually. May be there is some issues in my project configuration, but I am not sure it is related to that.

[yasirkula]

You're building the project using Build & Run, right? Not using an editor script to build it?

[codeswapping]

Yes, not an editor script

[yasirkula]

OK then my assumption was another plugin calling pbxProject.SetBuildProperty because otherwise, these lines have to work:

UnityNativeGallery/Plugins/NativeGallery/Editor/NGPostProcessBuild.cs

Lines 125 to 128 in 46eb0de

	pbxProject.AddBuildProperty( targetGUID, "OTHER_LDFLAGS", "-weak_framework PhotosUI" );
	pbxProject.AddBuildProperty( targetGUID, "OTHER_LDFLAGS", "-framework Photos" );
	pbxProject.AddBuildProperty( targetGUID, "OTHER_LDFLAGS", "-framework MobileCoreServices" );
	pbxProject.AddBuildProperty( targetGUID, "OTHER_LDFLAGS", "-framework ImageIO" );
