Creating extension for Notification.Name

Question

I'm following this tutorial for Notification Center, and it suggests to create an extension for Notification.Name to handle all names, so I created a new Swift file called Notification+Name.swift with these contents:

import Foundation

extension Notification.Name {
    static let URLContainerDidAddURL = NSNotification.Name("URLContainerDidAddURL")
}

But I'm getting the following error:

'Name' is not a member type of 'Notification'

What's going on? Why am I getting this?

Answer 1

Try this

 extension Notification.Name {
    static let URLContainerDidAddURL = Notification.Name("URLContainerDidAddURL")
}
