Readings:
The Swift Programming Language (Swift 2.2) (Links to an external site.) -  https://itunes.apple.com/us/book/swift-programming-language/id881256329?mt=11 (Links to an external site.) 
Pages 1-271
You will want to download that to iBooks and eventually read the entire thing.  The Swift Tour on Pages 3-33 you should know like the back of your hand.  Everything up through properties you should be familiar with starting next week.
Optional reading (Playgrounds which follow the book):
https://github.com/nettlep/learn-swift (Links to an external site.)
Highly recommend exploring portions of the book which don't seem clear in the noted playgrounds.  These implement all  of the examples from the book so that you don't have to type them in yourself.
Assignment
Problem 1 (20 points)  
Create a single view Project called Assignment2.
