Question

I've IPA which is uploaded on AppStore. On unzipping IPA I see two folders Payload and Symbols.

Symbols folder contains many files with extension .symbol

Any idea what would be these symbol files? Can we use them for symbolication?

Answer 1

Yes, it is debug symbols. They contain a mapping between encoded names and locations in your compiled code and the original function names among other debug information. Each <UUID>.symbols file represents either the main binary of you app or a framework that your app is using. You can find out which is which using mdfind (see example).
