Hi All,
I need to extend a class for NSCoding protocol conformance.
I tried the following code in the playground and get an error - required
initialiser cannot be declared in the extension. If I do not make it
required, I get an error asking to make it required ...and so on
class first : NSObject {
var name = "string" }
class second : first {
var age:Int
override init() { age = 21 }
}
extension second : NSCoding {
func encodeWithCoder(aCoder: NSCoder) {
}
required convenience init(coder aDecoder: NSCoder) {
self.init()
}
}
Any help is appreciated.
Regards,
