The cleanest solution to me here is to have lazy properties in case you want to have the db on top of your file. So let's say you have a FirebaseService class where you want to have Firestore.firestore() db constant to use it in all of the functions in that class:

private lazy var db = Firestore.firestore()

Or if you are using Firebase Storage:
