Issue with conforming to Objective-C protocol from Swift NSObject subclass

Question

This piece of code works absolutely fine in Swift 1.1

// Obj-C

@import Foundation;

@protocol HashableObject 
- (NSUInteger)hash;
@end

//          


        

Answer 1

In Swift 1.2 (Xcode 6.3 beta 2) you can override the hash property of NSObject as a computed property:

class Object: NSObject {
    override var hash: Int {
        return 0
    }
}
