X Notification Center

My type-safe Notifications with Blackjack and Hookers

⭐️	Key Features
🐧	Swift 4.0
🏰	Strong typed
🎭	Extendable

Why?

• Avoid string-based notification syntax 😡
• Avoid casting magic in notification handlers 🤢

func userNotificationCenter(center: NSUserNotificationCenter!, didActivateNotification notification: NSUserNotification!) {
        let userInfo:Dictionary<String,String!> = notification.userInfo as! Dictionary<String,String!>

    guard let type = userInfo["type"] as? String else {
            print("It can't be :(")        
    }
      
    if type == "LoggedIn" {
        guard let accessToken = userInfo["accessToken"] as? String else {
            print("It can't be :(")        
        }
    }
}
