I am using this code to get the Notification Center Device token.

It was working in Swift 3 but not working in Swift 4. What changed?

You can use like,

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let hexString = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    print(hexString)
}
