Added unit testing target to Xcode – failed to import bridging header won’t go away

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.
