“No such module” when using @testable in Xcode Unit tests

Question

I recently updated to Xcode 7 beta 5. I tried adding a unit test to an earlier project, but I am getting the error message \"No such module [myModuleName]\" on the @te

Here is yet another thing to check that is not listed. For me, it had something to do with my team, perhaps because our Team's Agent had not yet agreed to the latest License Agreement! Once I selected a different Team in my Target's General settings, AND then I specified a specific Deployment Target like 12.1 or 11.0, suddenly the "No Such Module" warning went away.

CocoaPods recommends adding inherit! :search_paths to your test target like so:

target 'App' do
  target 'AppTests' do

If you have some targets in your project - check your TARGETS in Module Name that you try to import with @testable import "TARGETSModuleName".

If you are using xcodebuild and find this problem, consider adding in a workspace flag to the build command.

Changed This

$ xcodebuild -scheme PowToonsTests -destination 'name=iPhone X' test

To This

$ xcodebuild -workspace PowToons.xcworkspace -scheme PowToonsTests -destination 'name=iPhone X' test
