Types are nice: recursive types, in Swift
What's a recursive type, what is it useful for, and how can we implement and use one in Swift? Let's find out!
Some time ago, I had hopes of completely masking one of my app's services' inner pagination logic. Ideally, that meant my Controllers or ViewModels wouldn't need to know anything about how the service handled pagination. Nothing. Not whether or not there was a next page of results. Not even the parameters needed by the service to retrieve it.
Seems obscure? The gist is quite straightforward:
func getItems() -> (results: [Item], next: (() -> [Item])?)
