Sometimes it is sufficient to inform the user that a process is loading or has been completed without prompting them to “Dismiss” the alert. Inadequate user experience design includes sending a signal whenever a user adds a song to their favourite list or library.
A notification pops up when a user likes or adds a song to their Apple Music library. An excellent method of providing the user with information in a clear and attractive format.
So I decided to create an open-source library that attempts to mimic Apple’s alerts in both form and function within the Swift UI framework.
The definition of a toast has eluded me.
With toast notifications, you can quickly inform the user of any changes. Typically, they report on the success or failure of an action taken by the user. The toasts are brief, to the point, and only take up a tiny fraction of the screen.
When a user receives a toast message, it won’t interfere with their workflow, but they’ll still get the information they need. There are no associated sounds or notification hubs on any platform; instead, they appear at the viewport’s bottom. (But developers can change that.)
For the first time, Android apps could make use of toast notifications. Currently, toast notifications are supported by the majority of platforms out of the box. Many popular web app development frameworks, including react-native and Ajax, support toast notifications.

Plan of Action
To display toast notifications on iOS, we’ll need to write some custom code, so let’s start by setting up a new project with the React Native CLI. The following command should be entered into the Windows or Mac terminal command line.
-
Launching the Initiative
First, let’s move into the directory where our work will be stored. Afterwards, start the next react-native service.
Then, launch the project in the iOS simulator by issuing the following react-native run-ios command from a separate terminal.
You can launch the project for an Android simulator by invoking npx react-native run-android.
-
Get Started Instructions
To begin, delete everything in the App.js file and replace it with the text below. Here, we use a SafeAreaView and a styled View to display the ToastMessages component.
At this point, make a components folder in the root directory and a file named ToastMessages.js inside it. Remember to include the following text. This example features four buttons built with the Button component and some styled text.
Now, in the components folder, please create a new Button.js file and paste the code below. We use TouchableOpacity to make a button and pass in the title and press props to do this.

iOS Toast Message Implementation Steps with Animation
Let’s start by making a utility function that will display Implement iOS Toast Message notifications. Make a directory at the top level and name it “helpers” to get started. Insert the following code into a file named toast.js.
The following functions use the React Native DeviceEventEmitter to send out notifications: info, success, and danger. Here, we’re releasing a string with the name SHOW TOAST, some options and a new type.
When the demo user enters an empty username or password and clicks the Login button, a Toast Alert with a blur effect will be displayed.
-
Create a new project in XCode as the first step.
Click “Next” to proceed to Step 2, where you will choose “single view application” as the project type.
Third, in the new window, label your project.
The fourth step is to head to Main once you’ve created a new project.
Select ViewController in the Storyboard, then drag UITextField from the “Show Object Library” onto the ViewController.
This process can be used for the password, too.
-
Next, head to Main
In the Storyboard, go to the “Show Object Library” tab and make your selection from the ViewController and UIButton dropdown menus, respectively.
The completed user interface, with the button added in Step 6, looks like this:
Once you have an interface similar to the one shown above, proceed to Step 7 and make an event for the login button.
Once the event has been created, move on to Step 8 and add the animation to your toast.
The method expansion we created earlier is called when step nine is completed (after login).
-
Bonus
What if you want to display a notification following a successful login, network operation, or other process completion? In addition to not wanting to make a separate Bool for each possible notification type. With just one warning and one switch.
It is possible to use an ObservableObject from anywhere in the project by creating and implementing an EnvironmentObject.
-
Toast
The view modifier must be applied to the root View in the tree, and subsequent views on the same ObservableObject must init a new AlertToast.
An immediate warning will be displayed using this technique:
-
Displaying Toasts
We could feed new information into the Toast.js module by pressing any of the buttons. Let’s display a toast message in the proper setting now. For each unique piece of text in a toast message, we’ll see a striking shade of colour.
To begin, create two new state variables named message and message type in the Toast.js file. Once we have the toast message, we will assign it to these state variables along with the appropriate message and type.
In this case, the return statement is examined to see if a message was received. We then display a View that contains a TouchableOpacity button. The container and the text are both of different styles.
Use the absolute position when you want the box to be at the very bottom. Line 4 also contains a colour variable that will give the container a unique background colour depending on the message.
The bottom messages will now change colour depending on which button was pressed.
-
Vanishing toast messages
Though our toast message will play indefinitely, it will eventually be removed. Let’s implement this in the Toast.js file.
We’ll use a brand-new state variable here called timeOut and set its initial value to 4,000 ms. A new ref, timeout reg, has been made as well. Having a ref already established is necessary because it will be referenced in multiple places throughout the code.
Then, a new useEffect hook will be available. In this case, we will use setInterval to trigger an action every 1,000 ms. By subtracting one thousand milliseconds from the timeOut state variable twice, we have made it equal to the timeOutRefvariable declared earlier. We’ll invoke the closest if it drops to zero after four iterations.
Clear the message field in closeToast() and increase the timeout value to 4000 milliseconds. Finally, call clearInterval to remove all data from the interval.
Last but not least, in one toast (), make sure the duration has been passed and assign it to the timeOut variable if it has.
Second, in TextMessages.js, you’ll want to send the duration variable set to 2,000ms.
When we finally reach SUCCESS, the toast message will disappear after just 2 seconds. At the end of 4 seconds, the ERROR and INFO toasts will go away.

Toast notifications are helpful because they show up quickly and provide users with crucial information without interfering with their ability to use the application. They are supported on iOS and require only a few lines of code to implement, though they are also available on most other platforms.
The issue with Toast messages is that users will no longer be able to see them once they have been removed. A user’s inbox can be configured to save Toast notifications so they can read them later. The inbox can also handle transactional messages like alerts and confirmations. This allows recipients to read any statement whenever they like.
