Swift Playgrounds

Learn serious code. In a seriously fun way.

Swift Playgrounds is a revolutionary app for iPad and Mac that makes learning Swift interactive and fun. It requires no coding knowledge, so it’s perfect for students just starting out. Solve puzzles to master the basics using Swift — a powerful programming language created by Apple and used by the pros to build today’s most popular apps. Then take on a series of challenges and step up to more advanced playgrounds designed by Apple and other leading developers.

Robots and drones await your commands.
Now you can make robots do incredible things with code you write yourself. Learn to program connected devices like the Sphero SPRK+, LEGO® MINDSTORMS® EV3, and drones by Parrot, and watch them come alive right before your eyes.

Real Swift code.
Real simple. Real playful.

Learning to code with Swift Playgrounds is incredibly engaging. The app comes with a complete set of Apple-designed lessons. Play your way through the basics in “Fundamentals of Swift” using real code to guide a character through a 3D world. Then move on to more advanced concepts.

What you see is what you code: Create code on the left side of your screen and instantly see the results on the right — with just a tap.

Conquer levels, puzzles, and coding concepts.

Starting with the “Fundamentals of Swift” lesson, you’ll tackle goals using the same code professional developers use every day. As you move along, more advanced concepts come into play. You’ll continually build on what you’ve learned and create even more complex code.

Fundamentals of Swift.

You’ll start out by learning the important concepts you need to understand code.

Master the basics,
then step up to more challenges.

In addition to the built-in library of lessons, Swift Playgrounds includes a collection of extra challenges — with new ones added over time. Go deeper on a topic you’ve already studied or try your hand at something new. You’re not just building fun creations, you’re building your skills, too.

A big world of playgrounds from a big community of developers.

Discover dozens of channels with fun new challenges created by leading developers and publishers. Subscribe to your favorites and you’ll receive their latest creations right in the app. Now there are no bounds to your playgrounds.

A new way to create code.
On the best device for learning.

Easily drag braces around code, wrap existing code in a loop, or choose from dozens of drag-and-drop snippets included in Swift Playgrounds — right from your iPad or Mac. Take full advantage of powerful Multi-Touch, multitasking, and split view capabilities on iPad. Also, enjoy the view from your Mac. The larger screen makes room for a new sidebar with a complete table of contents and quick access to other Swift files. Just tap, drag, or type text and numbers. Then interact with what you’ve created.

QuickType and coding keyboard.

Write an entire line of code with just a tap. With QuickType for code, the Shortcut Bar automatically and intelligently suggests commands as you go. When typing is the best option, iPad has an innovative keyboard designed for coding. Simply touch a key to access multiple characters, then drag to choose the one you want. Experience similar code suggestions on Mac, which comes with even more help to complete your code.

Snippets Library.

Quickly drag commonly used pieces of code from the Snippets Library to minimize typing.

Touch to edit.

Conveniently drag the boundaries of a statement around existing code.

Help is just a tap away.

If you come across a command that’s hard to understand, simply tap it and hold. A menu of options will appear. Choose the most relevant one and get the answer you need.

Jump-start your creativity with Starting Points.

Use what you’ve learned to create something brand new. With Starting Points, you can get a head start on more advanced coding, add multiple files to your playground at once, and use iPad features such as Multi-Touch interactions, accelerometer, and gyroscope. Personalize your project by adding graphics, audio, and more. Then easily share with friends, family, or the world. Students can also share code with classmates when teachers use Starting Points to create lessons.

Explore your creations in full screen.

Immerse yourself by using the vivid Retina displays of iPad or Mac. Simply tap the center divider, then drag to view your code or live project on the full screen. You can also customize built-in games like Battleship and Brick Breaker, then immerse yourself by letting them take up the whole screen.

See your code crawl, roll, or fly through the sky.

Watch your code spring to life by programming real robots, musical instruments, and drones. The Accessories channel is filled with engaging playgrounds that let you configure and control popular educational toys like LEGO® MINDSTORMS® EV3. And that’s just the beginning.

Sphero playgrounds let you guide this spherical robot through tricky courses, accelerate over jumps, and change colors.

Dash playgrounds challenge you to make it sing, dance and respond to sensor inputs to react to their environment.

MeeBot playgrounds guide you through coding Jimu Robot Meebot’s six robotic servo motors to make him move in lifelike ways. Or even dance.

Tello EDU playgrounds let you command multiple Tello drones to fly in a swarm, perform flips and other acrobatic movements, and push the limits of your creativity.

Explore robots, drones, and many other connected devices that support Swift Playgrounds.

Share your creation with
a friend. Or the world.

Send your code to a friend’s iPad using Mail, Messages, or AirDrop. Your friends can view it in Swift Playgrounds and even build on it by adding their own twists. You can also post a video of your running program to the web for the world to see.

Take things to Xcode.
Then take them further.

Because you’re working with real code, you can import and export directly between Swift Playgrounds and Xcode. So you can try out your ideas with the tool pros use to develop iOS and Mac apps.

Code is universal. So we teach it in many languages.

Swift Playgrounds is now available in 15 languages — Castilian and Latin American Spanish, Brazilian Portuguese, Traditional and Simplified Chinese, English, German, French, Italian, Korean, Japanese, Thai, Turkish, Dutch, and Swedish. Because we believe that everybody, everywhere should be able to learn to code.

Изучаем программирование с нуля в Swift Playgrounds

Если вы давно мечтали научиться программировать, то сейчас самое время. Осваивать новую перспективную профессию можно не выходя из дома: достаточно просто иметь при себе MacBook или iPad. Изучить азы программирования на языке Swift можно с приложением Swift Playgrounds. Разбираемся, почему стоит выбрать именно этот язык, и подробно рассказываем о приложении.

Почему стоить изучать Swift
Язык Swift был создан компанией Apple. Он используется для создания приложений под Mac и iOS. Этот язык считается быстрым и эффективным, а потому — перспективным. Всё больше разработчиков встраивают код Swift в свои приложения. В Apple объясняют, что обычный алгоритм поиска выполняется в Swift гораздо быстрее, чем в других языках, например в Objective-C или Python 2.7.

Ещё один аргумент в пользу Swift — он довольно прост в освоении по сравнению с другими языками. Опуская зубодробительную теорию: команды Swift — это простые слова, а ошибки кода легко выявляются при тестировании.

Почему приложение Swift Playgrounds подходит даже новичкам
Swift Playgrounds — англоязычное бесплатное приложение для изучения языка программирования Swift для Mac и iPad. Работает даже на Apple iPad (7-го поколения) и отлично сочетается с клавиатурой: вы можете набирать команды и писать код от руки. Это хорошая практика, которая позволит ускорить процесс и пригодится вам, если вы перейдёте на Mac и будете писать свой код в среде Xcode.

По своему устройству приложение больше напоминает видеоигру: пользователь пишет код и одновременно проводит анимированных персонажей по интерактивному трёхмерному миру, решая головоломки и выполняя задания. Так, в игровой форме вы узнаёте, что такое команда, код, компиляция, и осваиваете базовые термины и концепции разработки приложений.

Плюс приложения в том, что уже после пары уроков вы либо точно поймёте, что это не для вас, либо полностью погрузитесь и влюбитесь в процесс создания кода. Apple заявляет, что Playgrounds не требует каких-либо предварительных знаний в области программирования. К процессу можно подключить всю семью: освоить Swift с приложением смогут даже дети.

Как устроено приложение
У приложения простой интерфейс. Пользователь работает на так называемой «игровой площадке» — playground. Игровые площадки делятся на несколько типов:

• Learn to Code — простые уроки для новичков.
• Challenges — различные задачи, уже полноценные проекты.
• Accessories — здесь рассматривается работа с внешними устройствами (Sphero, LegoMindstorms, Dash).
• Starting Points — пустые шаблоны для обучения.

Выбираем нужный урок, например, Learn to Сode 1. В левой части экрана будут отображаться команды — их нужно выбирать и подставлять в правильном порядке. В правой части будем следить за нашим героем, который следует указанным командам.

Ваш прогресс от урока к уроку сохраняется, но все задачи можно выполнить заново, если хотите закрепить материал. Встроенные шаблоны помогают воплощать любые творческие замыслы и создавать настоящие приложения для iPhone.

Уровень сложности кода будет постепенно расти. В какой-то момент вам пригодится дополнительная литература — тогда выручит Swift Programming Language. Это бесплатное руководство доступно для загрузки в приложении «Книги».

Swift Playgrounds 1.6.1

September 25, 2017

What’s New

• Fixes an issue introduced in Swift Playgrounds 1.6 that would prevent some existing playgrounds from running. Learn to Code, the Hour of Code challenge, and most other playgrounds now work as expected. Some of the accessory playgrounds may require that you tap the New Playground button to get the latest version.

Known Issues

• After updating to a new version of Swift Playgrounds the app may attempt to update your existing playground documents to work seamlessly with this new version. Normally, this happens transparently. For the playground to be updated it must be on the device when the app launches.

If you have a playground in iCloud, but not on the device, then that playground will not be updated until it is downloaded. A similar situation can arise if you receive an older playground via AirDrop or email. In both cases, these playgrounds will be updated after Swift Playgrounds fully closes and is then re-launched.

To trigger the update manually, force the Swift Playgrounds app to close and then re-launch it. Swift Playgrounds will then update all the playgrounds you have stored on your iPad. For information on how to force an app to close see the following article: https://support.apple.com/en-us/HT201330.

In rare cases, you will need to create a new version of the playground using the “New Playground” button. This will retrieve the latest version of the playground, compatible with your version of Swift Playgrounds.
