Sunsetting Swift Compiler Bug Workarounds
If you have had to do something heinous in your code to avoid triggering a Swift compiler bug, you might consider…
#if swift(>=7)
#warning("Check if Swift bug is fixed and we can remove the '@unchecked Sendable'.")
#endif
In my case, certain presentations of indirect enums which reference each other (and that's totally legal!) trip a circular reference error in the analysis. The work around is to jiggle the order of your declarations, or dodge the analysis by marking it as an @unchecked Sendable.
The bug has been there since sometime in version 5, we are up in 6 now, so safe to say it isn't a priority. Setting a reminder that someday when you hit Swift 7 it is worth a review let's you forget about it now.
