ios - Tests stop working under xcode 8 TEST_HOST error

Question

I want to start tests under Xcode 8 and it fail in the beginning. My error is:

Could not determine bundle identifier for MyProjectTest's TEST_HOST: "/Users/jakubmazur/Library/Developer/Xcode/DerivedData/MyProject-ejeepybggxvekxajlyngopeahiex/Build/Intermediates/CodeCoverage/Products/Testing-iphonesimulator/MyProject.app"

Any idea what's wrong here? I try to clean project - nothing. In the Build Settings in my target in Packaging i change Product Bundle Identifier depends on configuration in my schema. It can have something to do with that, but not sure.

-- EDIT

Ok figure how to narrow the problem. When i change settings in scheme to use Build Configuration Debug instead of Testing seems to work, but I need separate configuration for testing.

Answer 1

For some reason the "Host Application" setting in the picture below was the problem for me. Selecting the proper target fixed this.

This ended up modifying the following values in my xcodeproj:

• BUNDLE_LOADER = "$(TEST_HOST)";
• TEST_HOST = "$(BUILT_PRODUCTS_DIR)/myappname.app/myappname";
