didUpdatePushCredentials not get called

Question

I want to implement VoIP notifications in my iOS application, But the didUpdatePushCredentials method never got called, I can\'t get the device token.

Answer 1

For me the solution was to enable:

P.S. I didn't forget to enable But enabling general pushes was important too. So full code is:

import UIKit
import PushKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        voipRegistration()

        return true
    }

    // Register for VoIP notifications
    func voipRegistration() {
        let mainQueue = DispatchQueue.main
        // Create a push registry object
        let voipRegistry: PKPushRegistry = PKPushRegistry(queue: mainQueue)
        // Set the registry's delegate to self
        voipRegistry.delegate = self
        // Set the push type to VoIP
        voipRegistry.desiredPushTypes = [.voIP]
    }

}

extension AppDelegate: PKPushRegistryDelegate {
    func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, for type: PKPushType) {
        let token = pushCredentials.token.map { String(format: "%02.2hhx", $0) }.joined()
        print("voip token = \(token)")
    }

    func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) {
        print("payload = \(payload.dictionaryPayload)")
    }
}
