Have:
protocol MyProtocol {
var value: Int { get set }
}
class Foo: MyProtocol {
var value: Int
}
class Bar: MyProtocol {
var value: Int
}
Want:
function generate(value: _) that infers the protocol-conforming class for instantiation:
let foo: Foo = generate(value: 1)
let bar: Bar = generate(value: 2)
The code doesn't compile because the init methods in the classes are missing
Add an init requirement to the protocol
protocol MyProtocol {
var value: Int { get set }
init(value: Int)
}
and this init method in both classes
required init(value: Int) {
self.value = value
}
Now you can create a generic generate method
func generate<T: MyProtocol>(value: Int) -> T {
T(value: value)
}
