Advanced iOS Bootcamp

Hold on tight and batten down your cranial hatches: this class explores advanced iOS development topics including concurrency, custom drawing, animated and interactive view controller transitions and maximizing the performance of iOS applications. In short, prepare your brain for an influx of iOS knowledge, in both Swift and Objective-C.

Our Nerds, Your Place

No matter where you are, our instructors can come to you. Need to take your team to the next level?

Learn More


Advanced iOS students should be current iOS developers who are looking expand their knowledge of frameworks and know what's happening under the hood of an iOS app.

Students in this class are usually full-time iOS devs, have a side business already up, an app in the store or have helped shipped an app with a team. We recommend at least three months of working iOS development experience prior to class.

While many of the Advanced iOS students have taken our Beginning iOS courses in Objective-C and Swift, plenty of others have learned iOS programming on their own or through another class. What matters is that you’re willing to devote yourself to learning the material. It’s important to make sure you’re comfortable with iOS basics so you won’t be overwhelmed by day one.

With that in mind, you’ll need the following before you embark on this path to Nerdvana:

  • A working understanding of both Objective-C and Swift.*
  • An understanding of the content in our Beginning iOS class; you can work through this pre-class workbook to make sure you're ready.
  • The ability to run code on your own iOS device.

*We are happy to supply course registrants who only know one of the two languages with a copy of our programming guide for the other language in advance of the course, so that you can be prepared for exercises in both languages.

Advice from the nerds

You will need to be able to deploy an application to your device before you come to class. For this class, you should have a pretty good idea how to do so. If Apple updates Xcode or iOS versions before class begins, you may update to the current version. However, you must make absolutely sure you can still deploy to the device after you update.

If you are unsure of whether you are prepared, do not know how to deploy to the device, or will be using one of our computers or devices, we are happy to help.
