Nice work and congrats on completing your final assignment! Parse is a great tool for quickly prototyping the backend for many apps. Even if you choose to ultimately replace Parse with a more conventional backend (e.g., Rails, Django, Node.js), that wouldn't really change the iOS code.

At this point, even though we've been building fairly simple iOS apps, we've covered a lot of the core concepts involved in iOS development. A lot of time and code in modern iOS apps is spent putting on the final 10% of polish, which is surprisingly time consuming and technically challenging. Here's a few additional topics that we didn't cover, but you should look into if you want to continue iOS development:

• Core Data. This isn't used by Facebook and many other companies, but is still asked about in iOS interviews.
• Multithreading. Grand Central Dispatch and NSOperationQueue.
• Custom Views. We used custom views via pods, and eventually you'll need to make your own!
• Custom Interactive View Controller Transitions. If you're tired of view controllers animating in from the right or from the bottom, then you'll need to implement transitions yourself.
• Gesture recognizers. We used a few tap gesture recognizers, and you'll also commonly need to use the pan and pinch gesture recognizers.
• Unit and integration testing. Once you're in an actual company (or earlier!), you'll need to start actually testing your code.
