Dispatch on associated type

[xwu (Xiaodi Wu)]

My question is: Is there another way to dispatch to different funcs based on the associated type (P.A) without changing the protocol (P)?

If by “dispatch” you mean specifically dynamic dispatch, then no:

Call proper function based on parameter's dynamic type

To add to Lantua's answer, there are three ways to get type-based dynamic dispatch behavior in Swift: Call a protocol requirement Call a (non-final) method on a class Manually check types with as? It can get confusing sometimes because the compiler will pick the best overload based on the static type, which can look like dynamic dispatch. But this list is the only real way.

It’s not clear to me why your function can’t be a part of the protocol, though.
