I have an app that uses Swift 4.2. I am going to update the Swift Compiler Language to Swift 5. But I have some confusion after my test. I was able to run async/await code when using Xcode 15 with the version set to Swift 4.2, and it was okay. But async/await code was developed in Swift5.5. Why it is okay? Is it related to the Xocde Swift version? And if I use Swift Compiler version 4.2 to run async/await code,what problems might there be ?
