Apple’s New App Will Teach the Next Generation How to Code

Feedback Loop

Due to arrive in the App Store this fall, the app is an educational tool. Through Boris and his levitating rhinestones, it teaches the fundamental concepts of programming, from commands and functions to loops and algorithms to variables and types. Other tools do similar things, including a seminal language for kids called Scratch. But Playgrounds teaches you to program not just through visual metaphors but with real code.

Minutes after launching the app, you can learn to string together a few commands. Then you can watch them execute. You can move Byte forward with a simple “moveforward ()” command. You can pack three “turnleft ()” commands into a function and use that to turn him right. You could move him up and down and across the floating island with several nested functions. Playgrounds teaches real problem solving without skimping on the syntax. It shows you what it means to “debug” a program, to find and remove mistakes. This problem-solving is so real, it can get frustrating. But that’s a good thing. As I played with the app, I got caught up in making sure that Byte behaved exactly the way I wanted him to.

The app is the next step on Apple’s path towards a new breed of computer programming.

The clear yet powerful lessons the app bring to the iPad are especially suited to kids, who are growing up with touchscreens, not keyboards, as their standard computing interface. Fareed Quraishi, a coder at a Swift-centric shop called Perfect, sees the app’s built in feedback loop—write program, see it run—as an ideal way of teaching programming to his young niece and nephew. “This could be used to teach almost anything,” he says.

But at the same time, this is an app that can serve experienced coders. Byte inhabits a “playground” for kids and novices. But you can also build your own playground—a place where you can see the results of any of your own code. Quraish, for instance, used the original Playgrounds to learn Swift, and he still uses it to test snippets of code as he writes, ensuring that a particular algorithm will work before pushing it into a larger application. Now that it’s on the iPad, he says, he can write and test code wherever he might be—even places unsuited to a laptop.

This is what Apple is aiming for: Swift everywhere.

Old News?

Others outside the Apple universe don’t quite see this as a revolution. “Apple Swift Playgrounds is a tool for learning Apple’s Swift programming language,” says Daniel Greenfeld, a coder with Internet consultancy Cartwheel Web who specializes in a language called Python. “Nothing new, just created and maintained by Apple.”

Indeed, the kind of visual feedback provided by Playgrounds is available with other tools and languages. Mike Curtis, head of engineering at Airbnb, points out that you can do much the same thing with Javascript, the standard way of building code for websites. “You reload the page and you see what happens,” he says.

For him, the real education won’t come from Playgrounds or any other new coding tool. “The thing that really teaches you how to code is wanting to build something,” he says.

Still, thanks to its size and influence, Apple has the power to drive a much larger shift towards languages that anyone can easily learn and use. Javascript certainly falls into that category. But it’s not as powerful other languages used to build smartphones apps. With Swift—and Playgrounds—Apple is bringing the ease of Javascript to the world of faster, more powerful languages. At the same time, other influential companies like Google and Facebook are introducing the strengths of these faster languages into the world of Javascript. Everyone will meet somewhere in the middle.

Polishing the Apple

The Apple faithful see Playgrounds eventually evolving into a system where coders can build anything for an iPad on an iPad, where creating apps is as visual and interactive as using them. “I feel like playgrounds are hugely important for the next generation of devs,” says Matthew Palmer, an independent 21-year-old coder based in Australia. “Not just the next generation in terms of young people learning to code, but what development will actually look like in a decade.”

Umberto Raimondi, a coder based in Italy, believes Playgrounds still needs improvement. He wishes it was more like IPython. But eventually, he believes, it will help far more people become coders. That’s a grand vision. But considering how rapidly code is winding its way into every corner of daily life, via phones and tablets and watches and the Internet itself, it’s a good thing to push for. Byte is a cartoon with a fanny pack. But he’s also just what the world needs.
