I have an object that has keyed properties:
func value(key: String) -> AnyObject?
func setValue(value: AnyObject?, key: String)
I wish to check if the value returned from the value
function with the same key from two different objects are Equatable
. Swift complains because Equatable
has a Self
reference and can only be used in generics. Is there a way I can check to see if the AnyObject
object returned from the value
function conforms to Equatable
?
Due to changes in Swift 2, I'm editing m'y answer
To check protocol conformance, simply use is
keyword.
But you can't do it when the protocol is using Self
(note the capital S).
So you could do:
if let myValue = myObject.value(myKey) as? Equatable {
...
}
