Xcode version
Xcode 15.0 Beta 6 (15A5219j)
Facebook iOS SDK version
16.1.3
Dependency Manager
CocoaPods
SDK Framework
Login
Goals
Warning-free compilation
Expected results
Compilation completes without warnings
Actual results
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')
Steps to reproduce
- Integrate FBSDKLoginKit to iOS project via CocoaPods
- Compile project with Xcode 15 Beta 6
- After compilation completes get warnings in compile target linking step
Initially Xcode doesn't specify which binary generates this warning, to find out it I copy target linking 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.
/Applications/Xcode-15.0.0-Beta.6.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -Xlinker -t ....very long args list....
Output:

Then I manually checked one of arm64 binary to confirm the warning by printing load commands:
otool -arch arm64 -l Pods/FBSDKLoginKit/XCFrameworks/FBSDKLoginKit.xcframework/ios-arm64/FBSDKLoginKit.framework/FBSDKLoginKit | 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 36
cmd LC_RPATH
cmdsize 32
path /usr/lib/swift (offset 12)
Load command 37
cmd LC_RPATH
cmdsize 40
path @executable_path/Frameworks (offset 12)
Load command 38
cmd LC_RPATH
cmdsize 40
path @loader_path/Frameworks (offset 12)
Load command 39
cmd LC_RPATH
cmdsize 40
path @executable_path/Frameworks (offset 12)
Load command 40
cmd LC_RPATH
cmdsize 40
path @loader_path/Frameworks (offset 12)
Code samples & details
No response
Now that Xcode 15 is officially released can you give an ETA when this will be fixed?
