To me, the latest xcode 13 (13A233) is able to archive project attached FB9178663 https://github.com/ffittschen/radar.apple.com/tree/main/FB9178663%20-%20Swift%20Compiler%20throws%20errors The issue should be resolved by apple.

beta3 still has this issue.

I have the same issue on xcode13 beta1 and beta2. Our project build failed in either debug configuration or release archive. Last week (with beta1) I tried creating a sample project using Kingfisher. and the sample app builds successfully without this error, kingfisher worked well.
