Future of Swift: A Sneak Peek at async / await
summary
Shows how to preview Swift 5.5 async/await by installing the latest Swift snapshot, enabling the flag -Xfrontend -enable-experimental-concurrency, and using withCheckedContinuation to wrap completion‑handler APIs. Demonstrates converting legacy URLSession calls into async functions, using @asyncHandler to call async from synchronous entry points, using async let (and Task.runDetached / Task.checkCancellation / handle.get) for parallelism and cancellation, and compares where async/await simplifies flow versus when Combine or RxSwift remain more appropriate.
