Version Compatibility page Swift book has incorrect information about version required for concurrency

[rtharston]

Describe the bug

The second to last paragraph of the Version Compatibility page of the Swift book incorrectly states concurrency requires '5.7 or later'. It should state '5.5 or later'. (My guess is someone did a 'replace all'.)

The same paragraph also says to, "set a deployment target of at least iOS 15, macOS 12, tvOS 15, or watchOS 8.0" which was correct at the time Swift 5.5 was released, but since Xcode 13.2 it is possible to use Swift Concurrency (but not all the new APIs) back to "macOS Catalina 10.15, iOS 13, tvOS 13, and watchOS 6".

To Reproduce

Steps to reproduce the behavior:

1. Go to Version Compatibility
2. Scroll down to second to last paragraph
3. See error

Expected behavior

State facts.

Actual behavior

State mix of old facts and new find-and-replace error.

The Swift book is now open source! 🎉

@rtharston We would appreciate it if you opened a new issue on the apple/swift-book repo instead to make sure this gets taken care of. Thanks! 🙂

Transferred to the TSPL repo and re-opened.

Wooh! Glad the book is now open source so we can more directly help with these fixes.

Thanks @amartini51 for reopening and moving this for me. 😀
