Apple Mach-O Linker Error When Building Starter Code

Question

I am using Xcode 8.2.1, Swift 3, and IOS 10.2 (for iphone simulator). I am trying to follow this tutorial https://www.raywenderlich.com/139322/firebase-tutorial-getting-started-2

I have not gotten to the Firebase stuff. Right now I am just trying to build and compile the starter code (should run fine). When I do this, however, I get the following error:

ld: library not found for -lPods-Grocr
clang: error: linker command failed with exit code 1 (use -v to see invocation)

How do I fix this? PS. I have done a pod install successfully.

Answer 1

When I first began working with Firebase I encountered many issues like this and for a while wondered if scrapping the whole Application and restarting was the best option. In the end the fix was simply, getting rid of the modules inside my app and uninstalling the pods then going back through the process of installing them. Sometimes a file will be place in the wrong directory so when the app goes to build it is looking for something that cannot be found and it fails. Good luck let me know if you have any more questions or issues.
