public headers aren't set as public for a static framework.

Make more classes immutable

Remove bogus PROVISIONING_PROFILE_SPECIFIER value from Pods project

Make PodVariant and PodVariantSet immutable

This value breaks code signing on Xcode 9 using CODE_SIGN_IDENTITY environment variable

Fix archiving when using Swift static libraries

This fixes archive builds, since the headers referenced by the module map are supposed to live next to it

Display a message when a pods source has changed during installation

Fix documentation

This way, we don’t need to rebuild the cache if there are multiple targets with the same dependencies on the same platform

Assignments return their r-values

Improve `pod install` performance for pods with exact file paths rather than glob patterns
