Jointly developing an Xcode project at SourceTree.
When I tried to pull what the member pushed and

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1

Is displayed and I can't build.
Apparently it's not a bad code, it seems to be a different cause ...

It would be helpful if someone could tell me.
Thank you.

The error looks like this.
