    I looks like you are compiling duplicate source files.

    1. Open PromisesObjC in the Project Navigator
    2. Go to the Build Phases tab
    3. Check the Compile Sources section for duplicates and remove the duplicate entry
    4. Clean Build Folder

    This occurs when you install Firebase via Swift Package Manager, and Google AdMobs SDK via CocoaPods. Unfortunately, this is how the current official documentation guides you. You end up with duplicated libraries in your project.

    After trying many things, I’ve got rid of this issue by installing Firebase via Cocoapods as well.
