Thank you very much. What if there are no .symbols in ipa? It will cause problems?

Thanks for your replay. I have checked MyApp.xcarchive/dSYMs and there is nothing inside. (built by Xcode 16.1) Then I used Xcode 15.4 to built it and generated .ipa again. There are .symbols files inside Symbols folder in ipa(.zip), but still, MyApp.xcarchive/dSYMs is empty. Do you have any clue why that happened? Why are there two kinds of files for generating crash reports? .symbols files and dSYM file and their aims?
