I need to install the GoogleSignIn for my iOS application, and I did so.
The issue is that the watchOS app inside the project stops working because of build failures that are caused by the GoogleSignIn package. I cannot figure how to fix it, because inside the project settings, that package appears in the list of Frameworks for the iOS target, and is not present into the list of Frameworks for the watchOS target, as you can see in the first image below.
