A naive "valueForKey:" operator in Swift

gistfile1.txt

operator infix --> {}
func --> (instance: Any, key: String) -> Any? {
    let mirror = reflect(instance)
    
    for index in 0 ..< mirror.count {
        let (childKey, childMirror) = mirror[index]
        if childKey == key {
            return childMirror.value
        }
    }
    
    return nil
}

//Example
struct MyPoint {
    let x: Float
    let y: Float
}

let point = MyPoint(x: 1, y: 2)
point --> "x"
point --> "y"

It seems not valid anymore in current beta (Xcode 6 beta 6), due to the childKey always returning an empty value. Could you confirm it too? THX

It seems that was a issue in Playground Xcode 6 beta 6. When using it in project, everything goes well.

infix operator --> {}
