When I try to build my project, I get a compile time error saying that a \"Module map file\" for my pod cannot be found and that I am missing a \"SwiftShimes\" module.
I had this issue only when I wanted to make an archive. On the other hand, debug worked fine. After a while I noticed that min iOS version was different between my Target, Project and Podfile min iOS version. After syncing them all to same value (iOS 11) Xcode offered me Validate Project Settings - Update to recommended settings option which I accepted and I was able to archive my project.
