I’ve been working a ton with Swift and iOS and ran into this problem when I had an existing project using CocoaPods, where when I installed a new cocoa pod module, I couldn’t import it.
Basically when I went to do the ‘Import ModuleName’ statements to bring the newly installed pods into my project, they weren’t in the Auto Complete dropdown! I tried updating, upgrading, removing, etc. NOTHING WORKED.
Until I actually clicked on the Pods project itself in the side bar, set the build target to ‘Generic iOS Device’ and clicked on ‘Product’ -> ‘Build’.
Once I did that, everything magically worked for me. Hopefully this will help you if you run into this same issue.
