I am trying to set up amplitude, I added amplitude ios sdk to my project, but I can't proceed and stucked on screen with "Set up amplitude". I see "Listening" for “Verify your installation in realtime”, but events don’t come. This is my code in iOS project: 

class AppDelegate: NSObject, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    func application(_ application: UIApplication,

                     didFinishLaunchingWithOptions launchOptions: pUIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {

        let amplitude = Amplitude(configuration: Configuration(

            apiKey: "9daef15edc05ef5dfda83709edb54080",serverZone: ServerZone.EU, defaultTracking: DefaultTrackingOptions(

                sessions: true,

                appLifecycles: true,

                screenViews: true

            )

        ))
}

And this is what I see for one hour already
