got this same crash any news on it

@kjoe07 Just wondering: Which Atlantis version and your iOS version are you using? I could not reproduce this issue in the last time and I'd like to investigate it again 👍

[kjoe07]

iOS 15.3 Xcode 13.2.1 macOS Monterrey proxyMan latest version, Install with swift package manager using urlSession for sockets, chafed to 1.14.0 and 1.9.0 and got the same error every time also have amplify as dependency and guess is using starscream

[NghiaTranUIT]

@kjoe07 if you're using Starscream to perform the Websocket, do you use NativeEngine by setting useCustomEngine: false?

for example:

let ws = Websocket(request: myRequest, useCustomEngine: false)

Ref: https://github.com/daltoniam/Starscream/blob/c68359159dcf0b5de9b536b9a959e9e435e968d3/Sources/Starscream/WebSocket.swift#L118

---

It's because, by default, Starscream would use TCPTransport rather than URLSessionWebsocketTask behind the hood. On the other hand, Atlantis only supports URLSessionWebsocketTask.

I now I don't use start scream it's a dependency for amplify not for my app my sockets connections are handle with url session

@NghiaTranUIT I've also encountered this. Does Atlantis support initialization elsewhere other than AppDelegate?

I wrapped Atlantis in a toggle switch in app settings. If a WS connection was mid-flight and I then enabled Atlantis (setup with no specific host), this crash would very likely be triggered.

[NghiaTranUIT]

Technically, you can initialize the Atlantis framework anywhere in the app, not just AppDelegate.

When the app is crashed, can you take a screenshot where the crash occurs?

It happens when I manually try to cancel URLSessionWebSocketTask with .normalClosure.

@vani2 Thanks. I will look on it today 👍

[NghiaTranUIT]

@vani2 let's update to Atlantis 1.21.1, it should fix the crash 👍
