Apple's Swift Playgrounds 4 lets programmers submit apps to the app store

Swift Playgrounds introduces programming by letting coders control a character named Byte.

Programmers learn basics like commands, variables, loops, and if-this-then-that operations.

The Swift Playgrounds introductory lesson – updated forSwift Playgrounds 4– expands to more challenging, elaborate tutorials.

Version 4 modernizes the tool significantly, starting with the iPad version.

That’s because Apple’s usual app store review process applies.

So don’t expect your “hello world” experimental app to appear.

And to submit apps, programmers will need anApple developer account, whichcosts $99 per year.

Apple offers free accounts to schools, though.

Swift Playgrounds apps can be sent to Xcode, Apple’s professional software development tool.
