In this project we built the kind of app you’ll see in thousands of different iOS job interviews around the world: here’s a JSON feed, please parse it and show in a table view. Sure, our specific version was about one feed, but the concepts – fetching data, using
Codable, rendering things into a web view, etc – are applicable anywhere.
But you’ve done more than just learn some new coding techniques. Michelle Obama once said “through my education, I didn't just develop skills, I didn't just develop the ability to learn, but I developed confidence.” And that’s true of you, too: each time you complete these projects you add another completed project to your résumé and you add another load of skills to your toolkit, but you’re also building the confidence that when you face a similar problem in the future you’ll realize you can look back on your work these last few days and have an instant refresher.
And it is a refresher. You see, you won’t remember the precise code you wrote today, and you might even forget class names like
JSONDecoder. But that’s OK: being a skilled developer isn’t about memorizing classes or methods – it’s about knowing concepts. And if you’re able to apply the concepts from this project with some concepts from projects 2, 4, and 5 to make something entirely new, then you’re doing a great job.
Today you should work through the wrap up chapter for project 7, complete its review, then work through all three of its challenges.
Once you’re done, tell other people: you’ve built another great app for iOS, and you’ve learned more about parsing JSON, tab bar controllers, and more.
You should be proud of what you’ve accomplished – keep going!
