Apple Mach -O Linker command failed

Question

After updating my POD install, Xcode sprouted a new issue:

Answer 1

I experienced the error when overwriting project.

Still encountered the error after:

• Changing the clang settings

• ionic cordova platform remove ios rather than just delete ios platform folder before each new build (and of course add the platform again)

• updating ruby as per instructions: https://forum.ionicframework.com/t/x-code-8-beta-2-apple-mach-o-linker-id-error/71998

Error was solved after changing to a different branch in github but perhaps one of the other troubleshooting methods played a part. Now all branches run on xcode without the Mach -O Linker Error.
