How to conform to NSCopying and implement copyWithZone in Swift 4?

I can't conform NSCopying protocol when I try to use the swift 3 way, My code is: 

public func copy(with zone: NSZone? = nil) -> Any {
    return type(of:self).init(self)
}

But an error appears: Cannot call value of non-function type 'ProductType'

What is the problem here?

I just found the solution, change the function for:

public func copy(with zone: NSZone? = nil) -> Any {
     return Swift.type(of:self).init(self)
 }
