When building my iOS app using Gym(Fastlane) the build fails with the following message:

```
...
❌  clang: error: unable to execute command: Segmentation fault: 11



❌  clang: error: linker command failed due to signal (use -v to see invocation)


** ARCHIVE FAILED **


The following build commands failed:
Ld /Users/jimmyers/Library/Developer/Xcode/DerivedData/msapp-dxyaimydokatmwfsxtnsmbsmvmaz/Build/Intermediates/ArchiveIntermediates/msapp/IntermediateBuildFilesPath/msapp.build/Release-iphoneos/msapp.build/Objects-normal/arm64/msapp normal arm64
(1 failure)
```

Looks like Clang is Seg Faulting. Here is the crash report:
