Chapter 5 - Swift Playgrounds

• Swift Playgrounds helps you learn and explore coding in Swift.
• Swift Playgrounds can satisfy your curiosity about what coding is and how it works, but it doesn’t really let you write apps.
• In Swift Playgrounds you create small programs called “playgrounds” that instantly show the results of the code that you write.
• Playgrounds are a great way to try some code and see the results immediately.
• Steps to create a Swift Playground
  1 - Launch Xcode
  2 - Click on Getting Started with a playground.
  
  3 - You’ll see a list of playground templates you can choose from, but for now we’re going to choose Blank.
  
  4 - Finally, Xcode will ask you to name your playground – the default name is "MyPlayground", you can give whatever name you want.
  
  5 - Click Create.

After playground is created, you'll see is a window split in two.

• Left panel is for the code.
• Right panel is for results.

On the right, once Xcode has built and run the code, you'll see this: "Hello, playground".
