No such module <product module name> in XCode Unit test

Question

I have a mixed objective-c and Swift project and I try to write Unit tests for it. My project name is: Alphaproject my product module name is: Alphaproject I set to YES Defines Module in my main Target (Alphaproject) and set to YES EnableTestability for Debug only in this same Target.

In my Test class, I try to import my product module name:

@testable import Alphaproject

Additional notes:

• all my projects files are only part of the main target
• my test files are only part of the test target
• My scheme for Test is set to Build Debug configuration.
• I also tried to clean the Build folder (ALT + Clean)
• The project doesn't have any error when compiling or trying to run tests except this "No such module Alphaproject"

Any other ideas?

Answer 1

In my case, the initial Xcode project was Objective-C, and I added testing targets that were Swift-based, and the import <Product Moodule Name> failed. I ensured that Defines Module was set to YES in Build Settings, but still got the error as indicated. The fix for me was to add a Bridging Header into the Objective-C main project.

Answer 2

OK! The problem was coming from the fact that I had arm64 in my Debug configuration for Valid Architectures. As the main target also doesn't contain arm64 in Valid Architectures, It couldn't apparently find the module... I think apple can make better work on displaying a proper error here. (Apple, if you read me, please)
