Swift Identifiable protocol

Swift Identifiable protocol

// This allows you to implement identifiable on any class/struct and automatially make them Equatable

protocol Identifiable: Equatable {
	var id: Int { get }
}

func == <T: Identifiable>(lhs: T, rhs: T) -> Bool {
	return lhs.id == rhs.id
}

struct User: Identifiable {
	let id: Int
}

let u1 = User(id: 1)
let u2 = User(id: 2)

u1 == u2
[u1, u2].contains(u1)
