TypedNotificationCenter

This framework is about rethinking Apple's NotificationCenter to be more typesafe and about removing uncertainity of the needed value being present in the userInfo dictionary.

Example usage

// SampleNotification.swift
import TypedNotificationCenter

enum SampleNotification: TypedNotification {
    struct Payload {
        let type = "test"
    }
    typealias Sender = MyCustomView
}

// OtherFile.swift
// Observe a notification and execute a block with the sender and the payload
var observations = [TypedNotificationObservation]()
observations.append(TypedNotificationCenter.default.observe(SampleNotification.self, object: nil, block: { (sender, payload) in
    print(sender, payload)
}))

// Post a notification
TypedNotificationCenter.default.post(SampleNotification.self, sender: self, payload: SampleNotification.Payload())

// Stop observing the notification, this is also called when the observation object deinitializes
observation?.invalidate()
