I am using Xcode 13.2.1
I had created one demo project for integrating code obfuscation, but facing above issue.
My app name is : COTest


I performed below steps:-
STEP- 1) ppios-rename --analyze --symbols-map /Users/Justmac/Desktop/TEMP/symbols.map /Users/Justmac/Library/Developer/Xcode/DerivedData/COTest-bsavpegzjpcdskanvimkgayjsktr/Build/Products/Debug-iphonesimulator/COTest.app
After performing this step the symbols.map file had been successfully created in TEMP folder.
STEP 2) ppios-rename --obfuscate-sources --symbols-map /Users/Justmac/Desktop/TEMP/symbols.map.
After this step storyboard outlets & action get renamed(only on storyboard) & generated the symbols.h file & showing error in that file.
