I've been reporting this problem for a long time now, and it's so bad I wonder if I'm just doing something wrong. Radar ID FB11236399. I've just added a much smaller code example that should be fairly easy to test. But generally speaking, Xcode can't inspect local Swift variables, or step over await calls. It's been this way as long as I can remember (since the introduction of async/await). Surely, if everyone was running into this, it would be fixed by now? Am I doing something wrong? It does...
