Using Swift protocols with generics

Question

I have a simple example that seems like it should work:

import CoreData

@objc protocol CoreDataModel {
    @optional class func entityName() -> String
}

         


        

Answer 1

From "The Swift Programming Language"

Because T is a placeholder, Swift does not look for an actual type called T.

As T is not a real type, it is maybe not useful to cast to T.
