I have an existing project that I am trying to add unit tests to. I'm on Xcode 10.1 and project is purely in Swift.
I start by clicking on "New Target..." In the first dialog I am able to choose the project but the dialog box for "Target to be tested" is grayed out.
I have tried to go ahead and add the test target without choosing and this results in my test bundle not being able to find my existing classes - "No such Module error"
Not sure what I'm doing wrong to prevent the this selection
Thanks for any help!
In Xcode 10.2.1, with your project open, click on the diamond with a dash in it:
Then down at the bottom left of the project window click on the '+' and select "New Unit Test Target".
