SwiftyNotifications

Swift helpers around Foundation's Notification.Name

SwiftyNotifications is an easy and type-safe way to work with Notification.Name in Swift.

Usage

Notification name objects can be created with string literals:

let somethingDidChange: Notification.Name = "SomethingChanged"

Add observers using block syntax; blocks are guaranteed to always run on the main thread, even if notifications are posted on a different thread.

somethingDidChange.addObserver() { notification in
	// Do something
}

Post notifications thusly:

somethingDidChange.post()

A type-safe generic type with identical syntax is available when using sender objects:

let boolDidChange: Notification.TypeSafeName<Bool> = "BoolChanged"

boolDidChange.post(true) // Must send a Bool

boolDidChange.addObserver() { notification, object in
	// `object` is guaranteed to be a Bool
}
