I'm currently using Google Drive SDK in my iOS app (Xcode 9, Swift 4). After manual linking of framework to my app I've got this warning (appears in console after app run):

objc[9082]: Class GTMSessionFetcher is implemented in both /Users/user_name/Library/Developer/Xcode/DerivedData/app_name-some letters/Build/Products/Debug-iphonesimulator/GTLR.framework/GTLR (0x1083eb628)

and

/Users/user_name/Library/Developer/CoreSimulator/Devices/some_numbers_and_letters/data/Containers/Bundle/Application/some_numbers_and_letters/app_name.app/app_name (0x106a34658). One of the two will be used. Which one is undefined.

What may solve this problem?

You can try clean project, delete Derrived Data and Clean Simulator.

It is a first that you can try to resolve this issue.
