By notifications, you can provide some great features to your users. You can keep your users informed of the alert and information of your application. Notifications are used to display some message with sound. In this post, we will learn about iOS Local Notification using Swift.
@Arvind I'm trying to show an alert with different sound than the default sound. The sound would be from the library/sounds within the iOS system. But not matter what I do i'm getting the default sound (I know it's possible to change it from server side but I want to change it from the device since the user can choose his own sounds). Now in your code I can see you create the UIAlertView,. Below is the code which I am currently using to trigger a local notification. Let center = UNUserNotificationCenter.current content.title = storedMessage content.body = 'Drag down to reset or disable alarm' content.categoryIdentifier = 'alarm' content.userInfo = 'customData': 'fizzbuzz' content.sound = UNNotificationSound.init(named: '1.mp3. If you haven't heard of Notification Center, you're missing out! It's a great way to help make your larger application easier to manage and develop. IOS Swift App From Scratch - Core Data.
So mainly here we have two types of notification, push notification and local notification. So let’s start with iOS Local Notification, and in the next post, I will explain you about push notification.

iOS Local Notification Tutorial using Swift
Creating a new Xcode Project
- For this tutorial, we will create a new Xcode Project using a Single View Application.
- I have created a Xcode Project named NotificationExample using Xcode 9.
- Once your project is loaded come to Main.storyboard, here we will create a button when the user taps the button we will display the notification.
Creating a Button in Main.storyboard
- We already learned this thing in the previous Xcode Button Tutorial.
- So what we need to do here is, we need to create a Button, and we also need to connect it with our ViewController.swift file as an action. If you are confused about these things, please go through the above given Xcode Button Tutorial.
- Assuming you have connected the Button created in the Main.storyboard with your ViewController.swift, we have the following code in ViewController.swift.
Requesting Notification Permission
- User has to authorize the notification request, then only we can display the notification. So in the viewDidLoad() function we will ask for the notification permission.
- Add the following code in viewDidLoad() function.
- After adding the above code, if you will run your application, you will see the output as shown in the below screenshot.

- Click on Allow, and you can fire the notifications.
Creating iOS Local Notification
- Now we will build the notification in the action function of the button. In my case the function is buttonCreateNotification().
- Now you can run the application to view notification. But remember before iOS 10 notification is only displayed when the application is in the background. So after clicking the button Create Notification, you have to press the home button to see the notification. This drawback is removed in iOS 10.

iOS Local Notification When App is in Foreground
- As I told you, we can display the iOS Local Notification when app is in foreground from iOS 10. For this we have a delegate called UNUserNotificationCenterDelegate. So first you need to add this delegate to your ViewController class.

- Then we can use the following method inside our class to display the notification when the app is in foreground.
- Now try running your application you will see the local notification even when the app is in foreground.
