Added unit testing target to Xcode - failed to import bridging header won't go away

Question

I added a new Test target to my Xcode project. My project has Swift code and Objective-C code, and has a bridging header. Upon either adding the bridging header to UnitTesting's build settings, or doing import MyTarget, I'm getting the error:

failed to import bridging header

I've tried:

• Adding the bridging header to project, unit testing and main target's build settings.
• Changing defines modules to Yes.
• Moving the bridging header file to the root folder.

I've also tried making a sample project, which built and worked fine. Taking everything I have over into a clean new project isn't an option at this point.

Answer 1

If you use CocoaPods as package manager, must set search path etc. Give a simple way,

Try adding this in your Podfile:

target 'YourProductTests' do
    inherit! :search_paths
    # Pods for testing
end

and pod install

It works for me.

If the above solution does not work for you, try setting manually:

1. Click your Test target -> Build Setting-> tab: All & Combined -> Swift Compiler -Code Generation -> Objective-C Bridging Header : add your xxx-bridging-header

2. Check "Search Path", set up value of Framework Search Path, Header Search Paths, Library Search Path according to your main target. Maybe some search path lose here, manually add again.
