Linking error for unit testing with XCode 4?
Your test bundle needs extra settings:
- Set Bundle Loader to
$(BUILT_PRODUCTS_DIR)/AppName.app/AppName(replacing AppName in both places with your app's name) - Set Test Host to
$(BUNDLE_LOADER)
(If you create a project from scratch and enable unit tests, these are set up for you. But if you add a unit test bundle to an existing project, they're not.)
