Method load() defines Objective-C class method 'load', which is not permitted by Swift 1.2

Question

I\'m using Parse and I\'m creating a PFObject subclass conforming to the protocol PFSubclassing! It was working all fine, but now I\'m using Swift 1.2 and it gives me this

Answer 1

Overriding load() never worked with Swift. Earier it was simply not called. I filed a bug for Apple back then (Bug ID 18423731), and recently I got a response that the issue has been addressed by explicitly informing the developer that this is not allowed in Swift.

extension UIButton {
    // !! never called
    override public class func load() { // Method 'load()' defines Objective-C class method 'load', which is not permitted by Swift 1.2
        super.load()
        println("not called earlier anyway");
    }
}

So.... don't. Even if the documentation says otherwise.
