Discussion

important:

You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration:

func notificationSettings() async -> UNNotificationSettings

For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.

Use this method to determine the user interactions and notification-related features that the system authorizes your app to use. You might then use this information to enable or disable specific notification-related features of your app.

let center = UNUserNotificationCenter.current()
let settings = await center.notificationSettings()
// Add code here to inspect or act on the settings.

When the user initially grants authorization to your app, the system gives your app a set of default notification-related settings. The user may change those settings at any time to enable or disable specific capabilities. For example, the user might disable the playing of sounds when a notification arrives.
