Swift Playground is a free app for children to learn Swift programming
This new app is Apple's initiative to educate the next generation on how to read and write code. Through the free app, children or anyone can write code through the tutorials which include nice graphics to educate them about the fundamentals of programming like loops and variables. Besides that, there is also a 'playground' mode that is like a sandbox mode where you can experiment with the code without any boundaries
At launch, Apple will be the sole provider of the programming lessons but Apple is opening up the app to educators for them to create individual lessons through Xcode.
