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

Question

I'm working on an iOS project and Xcode is showing me the following warnings:

warning: /var/folders/qj/lk4bdr_x5fs9cvcj4jgx61mmy6f8jd/C/org.llvm.clang.codytwinton/ModuleCache/2UNUM8IHHP92Q/Foundation-KJNK6ICRXLXW.pcm: No such file or directory note: while processing /var/folders/qj/lk4bdr_x5fs9cvcj4jgx61mmy6f8jd/C/org.llvm.clang.codytwinton/ModuleCache/2UNUM8IHHP92Q/Foundation-KJNK6ICRXLXW.pcm note: Linking a static library that was built with -gmodules, but the module cache was not found.

Things I tried:

• Remove derived data, clean build folder and build again
• Disable Clang Module Debugging
• Deintegrate and install Pods again
• Change debug information format to DWARF with dSYM File
• Remove the files shown in the log e.g. rm -rf /var/folders/qj/lk4bdr_x5fs9cvcj4jgx61mmy6f8jd/C/org.llvm.clang.codytwinton/ModuleCache/2UNUM8IHHP92Q/Foundation-KJNK6ICRXLXW.pcm
• Delete ModuleCache: rm -rf /var/folders/v2/vjx2r5k16tz36wn8v4yn_sth0000gn/C/org.llvm.clang.moraleda/ModuleCache

Any ideas?

Answer 1

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.
