"Missing required module 'XYZ'" on Unit Tests when using Swift Package Manager

I'm using Swift Package Manager on an iOS app on Xcode 11 following the instructions from https://developer.apple.com/videos/play/wwdc2019/408/

Everything looks great, except Unit Tests won't work now.

Before you try the above, quit Xcode, and delete your derived data folder (~/Library/Developer/Xcode/DerivedData). If you're using cocoapods, run pod install, and then re-open Xcode. This fixed the problem for me.

I was facing a similar issue in Xcode 14.1. Getting error Missing required module 'RxCocoaRuntime'.

My fix was:

  1. Go to the project target and select the Unit test target.
  2. Select build phases under the Unit Test target
  3. Select "Link Binary With Libraries"
  4. Added RxSwift and RxCocoa packages.

This appears to occur because SPM dependencies might not automatically be linked to test targets.

We can manually link it by:

  1. Clicking on your Xcode project file (e.g. Headlines)
  2. Select test target from the sidebar (e.g. HeadlinesTests)
  3. Navigating to Build Phases in the top bar.
  4. In the Link Binary With Libraries phase, add the required library from the SPM dependency (this looks like a white building within the SPM package 📦).
  5. You may also need to add the library to the Dependencies phase.

I saw this in Xcode 13 after I created a multi-platform app & had checked the box to create tests. The issue seems to be that Xcode created UI tests rather than unit tests as I had expected. I just made a new unit test target and everything worked as expected when importing my app in the test file.

After researching a bit, I got this fixed by adding -Xcc -fmodule-map-file=$(PROJECT_TEMP_ROOT)/GeneratedModuleMaps/macosx/<missing module name>.modulemap to OTHER_SWIFT_FLAGS in the test target.

Source:

PS: Use -Xcc -fmodule-map-file=$(PROJECT_TEMP_ROOT)/GeneratedModuleMaps/iphonesimulator/<module name>.modulemap if your platform is iOS.

UPDATE: Also, it seems that this is fixed on Xcode 11.2 beta2
