I have a Swift project in Xcode and I'm working with Firebase and cocoapods. When I build my project, I get 15+ errors. All of them are "Could not build module 'xxxx' and the 'xxxx' are things like CoreFoundation, ObjectiveC, os_object, CoreGraphics, etc.
I've deleted derived data, restarted Xcode, reinstalled pods, my deployments are all matching (even in my pod targets). I'm absolutely out of ideas.
Can anybody point me in the right direction?
