In our lessons setting up navigation controllers on the Apple Watch, we've learned how to set up the storyboard, how to use push controllers programmatically and introduced sending data to another controller and back using contexts and delegates. In this lesson, we'll pass data when you have a segue and learn how to dismiss controllers. …
Flat User interfaces are a lie. They are not completely flat. One effect continues to be used with them to show depth: Shadows.

The basic text type in Swift is String. Like a literal Double of 3.5, we can have a literal String. Enclose String literals in quotes like this …
