How to prevent notification permission when I launch first time?

I have a special button that requesting a permission to allow notification but I see the permission before I clicking the button. Does anybody know how to disable it?

Thank you!

Solution

I've been using in AppDelegate.swift

        alarmScheduler.setupNotificationSettings()
    window?.tintColor = UIColor.red

    let notificationSettings = UIUserNotificationSettings(types: .alert, categories: nil)
    UIApplication.shared.registerUserNotificationSettings(notificationSettings)

So I just deleted it and resolved my trouble
