How to use enum of Notification.Name

README.md

Adding NotificationEnum.swift file to your project enables declaring enum of Notification.Name like this:

enum MyEvent: Notification.Name {
case foo = "foo"
case bar = "bar"
}

To send notification:

NotificationCenter.default.post(name: MyEvent.foo.rawValue, ...)

To observe:

NotificationCenter.default.addObserver(..., name: MyEvent.foo.rawValue)

To switch on notification.name:

switch MyEvent(rawValue: notification.name) {
case .foo:
    break
case .bar:
    break
}

NotificationEnum.swift

import Foundation

// Extension allowing enum of Notification.Names.

#if swift(>=3.0)
    
    extension Notification.Name: ExpressibleByStringLiteral {
        public init(stringLiteral value: String) {
            self.init(value)
        }
        
        public init(extendedGraphemeClusterLiteral value: String) {
            self.init(value)
        }
        
        public init(unicodeScalarLiteral value: String) {
            self.init(value)
        }
    }
    
#else
    
    extension Notification.Name: StringLiteralConvertible {
    public init(stringLiteral value: String) {
    self.init(value)
    }
    
    public init(extendedGraphemeClusterLiteral value: String) {
    self.init(value)
    }
    
    public init(unicodeScalarLiteral value: String) {
    self.init(value)
    }
    }
