It does build fails on Xcode 14 RC (14A309)

I don't know which channel will be good for reports this issue, so I post it on here. If this is not appropriate, please let me know.

Unfortunately Xcode 14.0 builds with Swift 5.7 on the 5.6 standard library, so we're going to run into issues like this until a better compilation condition is used. A possible fix would be to check for an actual macOS 13 framework rather than just Swift 5.7 but I'd hope Apple has a better suggestion.

Might be it can be checked with #if swift(>=5.7)?

I though #if swift(>=5.7) for stdlib, and #if compiler(>=5.7) for compiler.

Is this still relevant? I feel like this can be closed.
