Xcode warnings: Not such file or directory (.pcm files)

Whilst changing Format to "DWARF" instead of "DWARF with dSym" into > Build Settings menu > Build Options, answers the question, it will disable your ability to use a tool (like Firebase) to check the error logs.

A better solution would be on the command line to rebuild the pods:

pod deintegrate
pod update

same here since I added a target to my project to build a "development-version" of my app for testing purposes.

I've been get rid of theses warnings by setting (only for the target I added) the Debug Information Format to "DWARF" instead of "DWARF with dSym" into > Build Settings menu > Build Options.

In Build Settings set

Generate Debug Symbols = No
