推送通知功能在 Xcode 11 中没有选择器

Question

I am try to learn about push notifications on iOS. For that I am reading the Raywenderlich book.

On the other hand I have realised that, on Xcode 11, some rearrangements/changes have been done when configuring xcodeproj and one of them is the Capabilities and the selector for enabling Push notifications.

At this point i am not sure if it is on or off.

That's the content of entitlements file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>aps-environment</key>
    <string>development</string>
</dict>
</plist>

Which at least shows it is configured

In my AppDelegate I have the following code:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

    UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert]) { granted, _ in
        guard granted else { return }

        DispatchQueue.main.async {
            application.registerForRemoteNotifications()
        }

    }

    return true
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = deviceToken.reduce("") { $0 + String(format: "%02x", $1) }
    print(token)

}

When the app starts, push notifications permissions are requested but didRegisterForRemoteNotificationsWithDeviceToken is never called.

So, I know in previous versions of Xcode there is a On/Off selector so:

• Is it on or off?
• Is the fact that didRegisterForRemoteNotificationsWithDeviceToken never gets called related?

EDIT

• On a real device.
• Letting Xcode to deal with all the signing.

Yes, Just add it only, by adding it means that you accept that your app receive notifications.
