If you love to learn more, check out this tutorial on SwiftUI text. I’m not going to explain other text modifiers. That’s how you can use SwiftUI in Swift Playgrounds for iPad. foregroundColor modifier to change the text color. Actually, when you type “.” after instantiating the Text view, Playgrounds automatically shows all the available modifiers in the keyboard. SwiftUI provides various modifiers to customize the UI components.

The code you’ve written makes use of the SwiftUI framework and displays a text label on screen. Swift Playgrounds will then execute the code and display the visual result on a separate pane. You can press ENTER/return to accept the suggestion.Īssuming you’ve written the code, you can tap the Run My Code button to see the result. If you use Swift Playgrounds for Mac, the code completion works even better. It’s easier than I thought to type all the code entirely using the built-in keyboard. You tap the suggested keyword to add it to the editor.

On iPad, the suggestions appear in the software keyboard. While you type the code, it continues to suggest completions.

Swift Playgrounds for both iPad and Mac has a built-in support for code completion. This allows you to set the live view and show the visual results of running the code on the playground page. The trick to run and preview SwiftUI is to import the PlaygroundSupport module and write the last line of code.

How to run SwiftUI apps on Swift Playgrounds.

Here are what we are going to cover in this tutorial: If you have an iPad, I encourage you to follow the procedures to create the app too and share your experience in the comment section. I tried to write a simple Swift UI demo entirely using Swift Playgrounds for iPad and see if it works. To find out the answer, the best way is to experiment it. While I still recommend to get a Mac and learn to write code in Xcode, I’m also curious about the possibility of learning SwiftUI with this educational tool. Since the release of Swift Playgrounds v3.1, Apple added the support of SwiftUI. It would give you a more realistic programming experience.Įarlier, we published a new book on SwiftUI. Even if you just want to try out Swift, use the Playgrounds tool that come with Xcode. This is why I recommend my students to jump right into Xcode and learn the programming concept along the way. The gap between the iPad app and Xcode is quite large. You still need to get familiar with the development environment, learn how to use Interface Builder, and understand how to use the APIs provided by the iOS SDK. What you’ve learned using Swift Playgrounds doesn’t directly apply to Xcode. If Apple wants to really inspire people-both kids and adults-to write code instead of just learning what code is, it needs to bridge the gap between the colorful puzzle-solving of Swift Playgrounds and Xcode’s developer-centric environment. More importantly, there is a gap between Swift Playgrounds for iPad and Xcode on Mac. The code you write can’t leave the app it can’t even leave that particular puzzle page! Swift Playgrounds can satisfy your curiosity about what coding is and how it works, but it doesn’t really let you write apps. Swift doesn’t have a real command called collectGem() after all. It doesn’t make an app, it just guides Byte around and solves puzzles. Swift Playgrounds teaches concepts and uses real Swift structure, but it’s not real code. But he also highlighted one main issue of Swift Playgrounds. He mentioned that the app did teach him the programming concept in an engaging way.

Jason Cross from MacWorld wrote a great piece sharing his experience with Swift Playgrounds. Most of the Swift Playgrounds’ lessons do not prepare you to build a real world app. However, it’s not the real development tool. Swift Playgrounds is a great education app for newbies to get a taste of what Swift programming is and learn the basic programming concept. Personally, I don’t use to recommend Swift Playgrounds for iPad as the learning tool of iOS programming if your goal is to build a real app and make it available on the App Store. You can now run Swift Playgrounds on both iPad and macOS. Apple has built a Mac version of Swift Playground from its iPad app and released it last month.

The first version of the iPad app was released in September 2016 with the aim to make it easy for everyone to learn the basics of programming, in particular, the Swift programming language. I believe you know Apple released an app called Swift Playgrounds for iPad. “But how about Swift Playgrounds for iPad? Can I use the app to learn Swift and app development?” My answer is always “No, you need a Mac to run Xcode for iOS app development.” This is one of the most common questions for beginners.
