My Google Drive account holds private files that are used in my app, these files are regularly updated so I need to link my drive account to the app to download the files. I don't need any sort of user login/authentication since the only google account I am using is my own.
I've already set up the service account, created the key, and stored it in my xcode project, but how do I go about connecting to my account and downloading these files to the app in swift? The only research I could find was either in objc or is all about user-login.
