I recently downloaded Xcode 13.2.1. When I run the application it is crashing in iOS 15.2 in simulator while debugging. Also when already installed app i am launching by tapping on app icon it is running fine.

Here are backtrace:

Reason

The error here is EXC_BAD_ACCESS, and it is occurring because of ___lldb_unnamed_symbol.

Fix

As there is no minimally reproducible code or the complete crash log.

  • Assuming you are using the Debug schema check if a framework in your project had been compiled for Release builds, if that's the case change the schema to Debug for that framework.

  • From where we can check this? Also the app is running fine in iOS 14.X and running fine in real device having iOS 15.2. – Yogendra Singh Jan 14 '22 at 13:32
  • [Refer to this](https://stackoverflow.com/a/34643933/8704774) to know how to change between Debug and Release. There isn't much info that you have given if all the frameworks are set to Debug; you will eventually get to know where exactly your app is crashing. The app works fine on a device is mostly because it doesn't need to build everything when running. Supposedly the issue could be as simple as a failed assertion. If you have a minimally reproducible code only then, I can help you. This is not a generic issue that could have a general fix. The fix could be simple or fairly complex. – Asad Jan 14 '22 at 21:45
  • If you can't share the code, I might say you start looking after where `WebKit-[WKWebView loadRequest:]` ([load:](https://developer.apple.com/documentation/webkit/wkwebview/1414954-load)) has been called. [Refer to this](https://github.com/DerekSelander/LLDB) Set a breakpoint at that line and check using `lookup -X -l`. If it crashed earlier, use `sbt`. – Asad Jan 14 '22 at 21:55
