Working Code for getting push notification token - iOS 11 or greater, Swift 4

 let pushNotificationSettings = UIUserNotificationSettings(types: notificationTypes, categories: nil)

 application.registerUserNotificationSettings(pushNotificationSettings)
 application.registerForRemoteNotifications()

 return true 
}

Getting device token

<pre><code>func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

 let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
 print(token) 
}

In case of error

<pre><code>extension Data {
 var string: String {
 return map {String(format: "%02.2hhx", $0)}.joined()

Then you can do this:

Since you may need this token in different methods (like firebase, web engage, branch, etc), you can use a custom class to initial an APNS from the data containing both <code>data</code> and <code>string</code>
<pre><code>public class APNS {
 public init(deviceToken data: Data) {
 self.data = data
 self.string = data.map { data in String(format: &quot;%02.2hhx&quot;, data) } .joined()
 }

 public let data: Data
 public let string: String
}
</code></pre>
then you can use it anywhere you need:
<pre><code>func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
 let token = APNS(deviceToken: deviceToken)
 print(token.string)
}
</code></pre>

How to get the device token from new xCode 8, Swift 3 in iOS 10?

Here is the code to register notification:

<pre><code>func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -&gt; Bool { 

 DispatchQueue.main.async {
 let settings = UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil)
 UIApplication.shared.registerUserNotificationSettings(settings)
 }
 return true
}

func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {

 if notificationSettings.types != UIUserNotificationType() {
 application.registerForRemoteNotifications()
 }
}
</code></pre>

Here i get the token, but i get the following error 

<pre><code>Cannot invoke initializer for type 'UnsafePointer&lt;CChar&gt;' with an argument list of type '(UnsafeRawPointer)':
</code></pre>

<hr>

<pre><code>func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

 let chars = UnsafePointer&lt;CChar&gt;((deviceToken as NSData).bytes)
 var token = ""

 for i in 0..&lt;deviceToken.count {
 token += String(format: "%02.2hhx", arguments: [chars[i]])
 }

 print("Registration succeeded!")
 print("Token: ", token)
}
</code></pre>

Can anyone help me solve it?
