The error that I'm getting … Is that for every WebSocket task? Or does it crop up intermittently? I only have one websocket task and it happens intermittently. However when it does happen, it always happens after the webSocketTask:didOpenWithProtocol: has been executed. The should not happen. is there any way I can check the WebSockeTask at a low level to confirm that the underlying web socket is indeed connected? If I could then I'd be able to trouble shoot this further

Hi Eskimo! Thank you for looking into this, highly appreciated. I have a session manager that I use for REST calls, and I made the websocket extension a part of that and am using the same session to create the webSocketTask. Was this a bad idea and should I have a separate session altogether for the websocket code? The error that I'm getting in the completeError method is the following: 2022-01-07 11:07:23 3 - WebSocketExtension in didCompleteWithError Error Domain=NSPOSIXErrorDomain Code=57 "Socket is not connected" UserInfo={NSErrorFailingURLStringKey=https://xxxxx.com/, NSErrorFailingURLKey=https://xxxxx.com/, _NSURLErrorRelatedURLSessionTaskErrorKey=(     "LocalWebSocketTask <7680DF77-1C5B-46E1-A67D-AB0E0289EC6C>.<6>" ), _NSURLErrorFailingURLSessionTaskErrorKey=LocalWebSocketTask <7680DF77-1C5B-46E1-A67D-AB0E0289EC6C>.<6>} I get this for the WebSocketTask after the webSocketTask:didOpenWithProtocol: as completed I also get the same error in the webSocketTask.receive method. Once I get this error in this method, my retry logic in the websockettask.receive() method kicks in and it just makes the problem worse.

Same here. Xcode version 13.1 Big Sur 11.6.1 iPhone 13 Pro Max Watch Model: A2095 Apple, please address this, it's extremely frustrating. Just how many times does it need to make my iPhone ready for development?

I also have the same issue with Xcode 13.1 This is extremely annoying sometimes it takes 20-30 minutes. Xcode 13.2 beta also has the same issue

This issue has disappeared with iOS 15.2 Beta 3 released yesterday.

Hi Ivan, I can also confirm that the 14.3 simulator runtime is missing from the downloadable runtimes area. My issue is that I need the latest WatchOS 7.3 simulator runtime which is also missing. I suspect Apple will address this soon, but perhaps until then you can re-download Xcode 12.3? That should still have the 14.3 iOS runtime still available
