Issue: the background task support is unavailable when using the swift package.

I think we can move the constraint to SwiftQueue folder and remove it from iOS folder

Oh sorry you also moved the file. Seems like SPM didn't like that

Exactly, I have already done it, the issues is that BackgroundTasks is available for iOS 13.0 + and tvOS 13.0 +, it's not available on macOS, nor in the watchOS.
