Xcode – Test class File is part of module, ignoring import

I just stumbled on the same problem, and your post was helpful. What I found out is by change the Product Name to AppNameTests, as per your example, then the product module name is reflected correctly and you don’t have to add Tests at the end of $(PRODUCT_NAME:c99extidentifier). c99extidentifier seems torefers to Product Name.


  • select your test target in Project
  • navigate to Build Settings -> Packaging
  • change the Product Name to your previous test target, likely appending Tests
  • I believe the rename as per Apple’s renaming a project doesn’t include the updating the module in @testable, so I had to do this manually
