Swift: Writing Testable Code

- [Mark] Modern day app development is a complicated process. There's a lot of moving parts to consider, and it's nearly impossible to catch every edge case. Humans make mistakes all the time and it's unreasonable to expect otherwise. That's where writing our apps in a testable way can help make our lives better. Hi, my name is Mark Difranco, and I'm a freelance IOS engineer. In this course, we'll cover how to architect your app to make testing a breeze. I spent the last year optimizing this process for Swift, so I'm excited to share it with you. As we progress, we'll be building a sample speedometer app.

We will display the user's current speed and warn them when they exceed a set speed. Let's get started.
