Experiment[edit]
Create a directory within your "project" directory.
cd ~/projects
mkdir project-1201
cd project-1201
Edit a new file named "main.swift"
emacs main.swift
For this project you'll repeatedly edit the same file. It's probably easiest to test this file within emacs by typing: M-& (async-shell-command) and observing the results. For each question, be sure to understand the behavior before proceeding to the next question. It will be helpful to record your answers and reasoning for later review.
