Twilio Client iOS SDKを使用して VoIP アプリを開発しようとしています。私のアプリは、バックグラウンドでないときに着信を受け取ります。バックグラウンドモードについてはPushKit Framework、Appleが提案するように使用しようとしています。しかし、私のアプリは に登録されていませんPushKit。メソッドdidUpdatePushCredentialsが呼び出されていません。
これは私のアプリのデリゲートと設定です:

import PushKit;
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var voipRegistry: PKPushRegistry!;
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
if UIApplication.instancesRespondToSelector(#selector(UIApplication.registerUserNotificationSettings(_:))) {
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound], categories: nil))

}
