Thanks Quinn, I ran into what appears to be a bug involving websocket after migrating my app to Swift 6 Concurrency. I spent a lot of time trying to work out what was wrong, and then came across your post on this topic, and concluded that it was likely a bug in URLSessionWebSocketTask, rather than in my own code. I then started looking at the Network framework, then discovered the NWWebSocket package, struggled with it for a few days, then got a clue off the Issues for that repo, and finally worked it out & got it working at 1 am this morning. It was a painful & time consuming process, but would have been far more painful without your post from June last year. Thankyou! Andrew

Thanks, that terminal app command suggestion was helpful in fixing a preview crash problem that I had. There were two additional things that I had to do: 1 - if the simctl utility is not on your path (likely the default case), then point your terminal at: Applications/Xcode/Contents/Developer/usr/bin (you may need to unhide hidden folders and/or open the Xcode package), and do the command as: xcrcun ./simctl --set previews delete all 2 - the -set option actually requires a double dash: --set
