When running this code from command line it works fine. System Version: macOS 12.0 (21A5294g) Tested Playgrounds both iOS and Mac platform. Both failed but the code is fine. It is just a Playground issue. Could someone make sure this bug was filed with the XCode Playgrounds team.

@eskimo we know async {     async let a = doIt()     async let b = doIt()     async let c = doIt()     async let d = doIt()     let results = await [a, b, c, d]     for result in results {         print("  \(result)")     } } will not run in a Playground. We need the bug fixed :-)

For me ... Testing - UI (Compose / SwiftUI) (instrument) & Unit & Integration & End2End & CI/ CD is very important. It is the foundation of Clean Arch. And you are not thinking long term ???
