Reading Assignment #1

Due: Feb 2, 2020, 11:59 pm, v1

Quiz

The quiz is a relatively easy jaunt over the following reading, but it is timed: you will have only 30 minutes to complete the quiz after you have started it.

Therefore, I encourage you to read all the assigned reading ahead of time, as 30 minutes might not be sufficient to look up all the answers. More importantly, you will be using all of this information in your projects.

This is individual work; you may not collaborate with others. You may use online resources to complete the quiz.

Objective

The goal of this and the next reading assignments is to do a breadth-first scan of the entire Swift language. You can take a quick tour here, and feel free to consult the language reference, but your main reading is the Swift Language Guide. Weird / important topics are in bold.

This "assignment" consists of taking the above quiz on this material.
