What is this red line and what does it mean? This is Xcode 7.3, Cocoapods 0.39.0
After typing out the import I don't see any errors or warnings. I can use the library with no problems. The library itself has warnings but those are related to Xcode 7.3 changes to swift. I have never noticed this before.
Sometimes Xcode says my Pod project does not have recommended settings, but this still happens after applying the recommended settings.
