Local Notifications with Swift 4

Before we begin, you can download the initial draft. The application is a table with a list of types of notifications.

Now, if you tap on any line, Alert pops up with the name of the notification. By the end of this tutorial, this action will send a local notification with the contents of the string. In addition, the user will be able to interact with this notification, choosing to do this or that action.

Before your application can send any notifications, the user must give their consent to this. To do this, when you first start the application, you must fulfill the request for sending notifications, so that the user can approve or reject it.To create such a request, go to theAppDelegate class and import the UserNotifications framework.

import UserNotifications

In the class properties, create a new notificationCenter property and assign an instance of the UNUserNotificationCenter class to it to manage notifications. This will be our notification center.

let notificationCenter = UNUserNotificationCenter.current()

Go to the didFinishLaunchingWithOptions method and declare the options, which will contain the options available for our notifications. In total, we now have four properties available: badge, sound, alert and carPlay.

let options: UNAuthorizationOptions = [.alert, .sound, .badge]
