StartApp -> No such module 'StartApp'

Using StartApp in a Swift app I have this issue (Xcode 7.3.1). On the line:

import StartApp

I keep getting this error message:

No such module 'StartApp'

I have my StartApp.bundle and StartApp.framework set, and the Framework Search Paths are also set.

I already used StartApp in an Objectiv-C app before and I did have this problem.

Any idea to solve this issue would be welcome.
