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

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?

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

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

Does this issue get resolved? I am having the same issue after installing the newest FacebookSDK cocoapods.

The only solution I found

  1. Setting the Debug information format for Debug to "DWARF"
  2. Setting GCC_PRECOMPILE_PREFIX_HEADER=NO (this should only be done if making a static library).

I solved this issue by removing all derived data of all my apps. I used these steps:

  1. Open Locations tab in the Preferences of Xcode
  2. Click on the tiny arrow button at the right side of the Derived Data path
  3. Delete the DerivedData folder in Finder
  4. Restart Xcode
  5. Rebuild app
