After updating my Xcode to 10.2 and doing the Swift 5 migration, I got an errors in the Test Target of my dynamic framework

Cannot load underlying module for ''

any idea?

If I comment out my import in my test file

@testable import

everything compiled ok

thanks

Two things:

Have you tried doing a clean build? It’s possible that Xcode 10.2 is trying to use some build product created by the earlier Xcode and hence getting confused.
If that doesn’t work, try create a new project from one of the built-in templates and see if that has the same problem.
