It seems like SwiftFormat runs anyway, but just ignoring the config file contents, eg Pods/* is not excluded. There may be something obvious that I'm doing wrong, so please do let me know if so. --swiftversion 5.8.0 produces the errors as well, but --swiftversion 5, --swiftversion 5.6, and --swiftversion 5.7 do not.

@michaeldclifford can you run with --verbose mode and share the file that it got stuck on? It will be the last one logged before the failure to terminate message.

Although I was able to reproduce this several times, after a machine restart it no longer appears to be an issue. I'm afraid I've no idea what was causing it, as it now works as expected.

Thanks 🙂
