UI Testing in Swift Package

Question

I am building a Swift Package library that provide some UI components, for both macOS and iOS.

I would like to be able to test this codebase and cover my code with unit test for both platforms.

Is there a way to manage that ?

Answer 1

As of Swift 5.4, the Swift Package Manager doesn't provide that functionality out of the box.

To carry out UI tests, you need to create a separate app (in its separate xcode project), whose only purpose is to import the package and run UI tests via xcodebuild commands (as swift test won't work).
