DAY 25

Project 4, part two


If there’s one Martin Fowler quote that I love, it’s this: “I'm not a great programmer; I'm just a good programmer with great habits.” Today we need to add some more functionality to our project, but we’re faced with a choice: do we take the easy route or take the harder route?

As you’ll see, sometimes the “easy” route ends up being hard in the long term, because we need to maintain that code for a long time. The harder route takes a little rewriting of our code, but it’s one of many steps you’ll take towards having better coding habits – an important skill to have!

Today you have two topics to work through, and you’ll meet UIProgressView, key-value observing, and more.
