swift-async-algorithms can be used in earlier versions of Xcode if you checkout an earlier tag. They just moved forward more quickly. Async / await's backport no longer causes crashes in Xcode 13.4, but it does have the downside of being the Swift 5.5 runtime, which has several unfixed issues, unfortunately.

  Can't find them at the moment (check the Swift forums), but the two big issues I've seen reported are both in TaskGroup. One is a runtime crash under certain conditions, the other a major performance bottleneck when adding thousands of child tasks to a group. Both have workarounds, but they can hit you when using back deployment or any OS that has the 5.5 runtime (iOS 15 - 15.3 for instance). Wouldn't be showstoppers for me, just something to be aware of.
