Agenda

1. Setup: GIF Scrubber

2. Activity: Optionals
   • Understand how the Swift programming language handles cases where a value may not exist for a variable or constant.
3. Recap: Develop in Swift Tutorials
   • A further opportunity to consolidate concepts learned in module 1, and to learn a few new ways to write apps using the features of Xcode.
   • Chapters 1, 2, and 3 are all good choices to try this week.
