I was wondering if anyone else was having this issue when distributing their iOS App for Ad Hoc or Development deployment with Xcode 13.3 RC. Xcode generates the following error 'ipatool failed with an exception' with references to 'libswift_Concurrency'. It only seems to happen when the following is true: The App utilises Swift Concurrency The Deployment Target is set to 14.0 Disabling rebuilding with Bitcode seems to work around the issue however this is less than ideal. Feel free to reference my feedback FB9951218 where I've attached a minimal project that reproduces the issue.
