Now you should understand how things work on a basic level in Xcode. Let's start designing the UI of this app, right in Xcode!
A quick rundown of a typical Xcode workflow - how an app gets built, and how the interface works. Get acquainted with Xcode beyond the playground.
Without logic, there's not much a program can do. Conditional statements let your code make choices based on inputs.

Sometimes you need to express multiple related values. Swift has a few different collection types, that contain multiple instances of similar values.
Swift operators should look pretty familiar - the basic arithmetic functions, as well as a few others.
Dive into Swift by learning about your first 'building block' of code - variables and constants. Using Playgrounds in Xcode is the quickest way to get started!
