I feedback from the bug I filed with apple. The most likely cause is that the CFSocketStream has been overreleased by the app. CFSocketInvalidate should not cause SocketStream to be deallocated inline since it took an extra retain on itself before calling CFSocketInvalidate.

Hi @eskimo Your thorough investigation is appreciated. For context I am using rabbit client. This library uses GCDAsyncSocket. Unfortunately we are bound to use this library for the medium term because of the development effort required to modify our comms with our backend services. I filed a bug using Feedback Assistant. The reference is FB13091139

My app would have no crashes if it were not for this crash. On average the crash occurs 5 times a week. The most recent version of iOS this crash has happened on is 16.6. It looks like it has occurred on every version of IOS 16. I've added a crash log for iOS 16.6 Crash Log iOS 16.6

Hi @eskimo Thanks for the reply. I've attached the crash log which I took from XCode. Any assistance is greatly appreciated Crash Log

The backtrace was too large to add so I've added it in its entirety here https://pastebin.com/SmrpwrkY

In my case this was caused by users copying and pasting into a UITableView Form. The solution was to not use cell reuse. This can be easily accomplished by adding something like the row number to the cell identifier string.

Yes, I'm using a few third party libraries. I am certain that none of them have any copy & paste code.

No. There's absolutely no code in my application to do with copying and pasting programmatically.
