SDK Version

6.12.1 integrated via CocoaPods (AppsFlyerFramework/Dynamic)

What did you do?

Compile iOS project with new Xcode 15.0 Beta 6 (15A5219j)

What did you expect to happen?

Compilation completes without warnings

What happened instead?

Compilation competes with following warnings:

ld: warning: duplicate LC_RPATH are deprecated ('@executable_path/Frameworks')
ld: warning: duplicate LC_RPATH are deprecated ('@loader_path/Frameworks')

Please provide any other relevant information.

I manually checked arm64 binary to confirm the warning by printing load commands:

otool -arch arm64 -l Pods/AppsFlyerFramework/binaries/xcframework/dynamic/AppsFlyerLib.xcframework/ios-arm64_armv7/AppsFlyerLib.framework/AppsFlyerLib | rg -A 2 -B 1 LC_RPATH

And got output, where we see that @executable_path/Frameworks and @loader_path/Frameworks are defined twice:

Load command 18
          cmd LC_RPATH
      cmdsize 40
         path @executable_path/Frameworks (offset 12)
Load command 19
          cmd LC_RPATH
      cmdsize 40
         path @loader_path/Frameworks (offset 12)
Load command 20
          cmd LC_RPATH
      cmdsize 40
         path @executable_path/Frameworks (offset 12)
Load command 21
          cmd LC_RPATH
      cmdsize 40
         path @loader_path/Frameworks (offset 12)

Initially Xcode doesn't specify which binary generates this warning, to find out it I copy compile command from Xcode's build log and run it directly in the terminal, adding argument for additional linker logging: -t Logs each file (object, archive, or dylib) the linker loads. Useful for debugging problems with search paths where the wrong library is loaded.

I have noticed the same warning as well on beta 8, but only after updating to version 6.12.2. If I use version 6.11.0 with Xcode 15 beta 8 then I do not see this warning.
