If/when you re-run pod install it's just going to come back, which is unfortunate!

I ended up adding a post_install hook to my Podfile using "v1.0" of the accepted answer in this SO post (couldn't get v1.5 to work) and it's preserving the fix after a pod install: https://stackoverflow.com/questions/30244675/how-can-i-modify-other-ldflags-via-cocoapods-post-install-hook

I think TwitterKit project -> TwitterKit target -> Link Frameworks and Libraries , the libTwitterCore.a is unnecessary

I use TwitterCit 3.4.2 internally to reference TwitterCore, so deleting the error can't be deleted.
