Linker fails with exit code 1.

I have a simple iOS swift 3 project, running in XCode 8.1 (8B62), that compile fine, and execute as well. Push it on my SVN repo, and my colleague get it, working too. All is OK.

We have to add a pod, so done it. (the pod is a little log tool based on Cocoa Lumber jack, and is used from long time over all of our projects) My 2 colleagues make it work in few minutes. But, I get the linker fails error. The linker error is about -lCocoaLumberjack, but if I add any other pod instead, the first pod encountered by the linker make it crash.

I have tried every trick proposed on other similar questions, clean project, clear derived data, restart xcode, change architecture parameters, clean pods, deintegrate pod, clean the tests host, removed tests target ... a thousand times

I have deleted the project, and download it back from repo, and get the same problem.

I have also updated cocoapods to v1.1.1. (same as my colleagues). use_frameworks! or not never seems to do something different.

Since my colleagues has the exact same projets, sources, and pods, i think i can exclude project, workspace, build configuration/settings errors. So where can i check additional configurations about linker, xcode, or environnement variables that could cause the problem ?

Thank you for any help

log from the linker if it could help :

Last chance today, I have uninstalled and reinstalled Xcode. That's solve the problem. I only can suppose that it was somehow corrupted.

  • Clean and build the project then run the app
  • Still Error? Check Enable Bitcode Option in Build Settings section.

Try to reverse the option and try again (If it is on , off it else vice-versa)

This problem sometimes occurs due to mismatch of "Enable Bitcode" option between your project and libraries.
