Swift Playgrounds has been updated to include a specific app playground, making it even easier to Create and view apps. In this article, we will guide you through the process of creating an app using Swift Playgrounds, step by step.

Getting the New Playground

Before we dive into the app creation process, you need to ensure that you have the latest version of Swift Playgrounds. Once updated, you will find a new playground called "app" in the app library.

Opening the Playground

Once you have the new playground added to your library, double click on it to open it. The playground now consists of three windows: the file window on the left, the coding window in the middle, and the preview window on the right. The preview window is the most exciting addition in the new app playground as it allows you to Instantly see the results of your app creation.

Adding Text

To add text to your app, navigate to the coding window and delete any existing code that may be present. Then, use the text("") function to add text. As you Type, you will see the text instantly previewed in the preview window. This real-time update feature makes it incredibly convenient for making small changes to your app.

Formatting the Text

Want to make your text more interesting? You can easily format it in Swift Playgrounds. For example, you can change the font size by using the .title modifier, make it rounded using the .rounded modifier, or make it bold using the appropriate option.

Adding an Image

In addition to text, you may want to include images in your app. To do so, first, locate the image file on your computer and drag it onto the file section of the playground window. This action will create a new assets section where you can store all the images and other assets required for your app. To reference the image in your code, use the image() function followed by the name of the image file. The preview window will display the image accordingly.

Resizing the Image

If your image is too large, you can resize it to fit your app's design. To resize the image, add the .resizable() modifier to the image code and use the .frame(width: , Height: ) modifier to set the desired width and height. This allows you to customize the size of the image to suit your app's layout.

Finalizing the Code

By this point, you should have added text and an image to your app. Take a moment to review your code and make any necessary adjustments. Ensure that all your elements are properly positioned and styled. Once you are satisfied with the code, you are ready to move on to the next step.

Previewing the App

The beauty of Swift Playgrounds is the ability to see your app come to life in real-time. To preview your app, simply observe the changes taking place in the preview window as you make adjustments in the code. Small changes such as text modifications will be visible instantly, while larger changes may require you to restart the preview. Take this opportunity to fine-tune your app until it meets your expectations.
