Obviously, it’s a bit more complicated to explain how associated types work but once you get the hang of it, you’ll be using them more often. Protocols allow us to define a common interface between types An associated type can be seen as a replacement of a specific type within a protocol definition. In other words: it’s a placeholder name of a type to use until the protocol is adopted and the exact type is specified. This is best explained by a simple code example. Without an associated type, the following protocol would only work for the type we define. In this case: Strings. If we want to make use of the same logic for a collection of doubles, we would need to recreate a new protocol. Associated types prevent this by putting in a placeholder item: The associated type is defined using the associatedtype k
