Spring Cleaning Your App – Refactoring Safely – RWDevCon Session – Live Tutorial Conference

Have you ever run into a legacy app with a Massive View Controller or other architectural problems? In this session, you’ll learn how to give legacy apps a spring cleaning. You’ll learn how to iteratively split apart code, add testing, and prevent problems from happening again.

Have you been working with iOS for a few years now but always been a little bit too nervous to jump into Instruments and try to track down some problems in your app? Maybe I’m way off and you’re a little newer to the game and you’re just really interested in trying to improve your app’s performance. Either way, by the end of this workshop you’ll have a good feel for how to use Instruments to dive deep into what’s happening while your app is working and see exactly where the bottlenecks are.

Conference Highlights

This year, for the first time ever, we offered two optional pre-conference workshops:

Advanced App Architecture: This advanced workshop by Josh Berlin and René Cacheaux covered how to create a well designed boundary between subsystems, dependency injection, use case driven development, and more to result in a clean architecture for your apps.

Advanced Apple Debugging and Reverse Engineering: This “mind-blowing” workshop by Derek Selander covered how to wield the power of LLDB and other debugging tools and dig deep into code.

After the workshops, we had the opening reception for the conference. This was a chance for everyone to get to know each other, and enjoy some passed appetizers, beer, and mojitos! :]

The next morning, Marin Todorov kicked off the conference with his inspiring speech titled Reflect & Refactor. He challenged us all to take stock of our lives at this moment, and ask ourselves “what do you need right now?”

After that we started the main event of the conference: the 24 hands-on tutorials. The key difference is that instead of just watching the instructor talk, you code along with him or her!

Some of our most popular tutorials this year included Swift Playgrounds in Depth, Server Side Swift, Advanced Auto Layout, Machine Learning, iOS Design Patterns, and Swift Memory Management.

After two hard day’s work on tutorials, we switched over to inspiration talks. These are short, 18-minute non-technical talks designed to give you a new ideas and some battle-won advice, so you can go home energized and excited.

Don’t worry – aside from all of these tutorials and inspiration talks, we had plenty of time for fun too. We played board games at lunch, and during our Friday night party we had the first ever James Dempsey Game Show!

During the James Dempsey Game Show, contestants answered Apple and iOS trivia questions. Some were technical – like “Will it Compile?” – and some are non-technical, like “Who Said It – Jobs, Cook, or Ives?”

The last day of the conference was on April 1, so of course we couldn’t miss the chance to play an April Fool’s joke on everyone: the “release” of Programmer Dancing by Tutorials!

Then we had the real special surprise of the conference: all attendees got a free print copy of our new book RxSwift: Reactive Programming with Swift, and an advance copy of our upcoming book Advanced LLDB Debugging & Reverse Engineering (that isn’t even available on our site yet)!

Overall, the team and I had so much fun learning, getting inspired, and meeting friends both new and old. We can’t wait for next year!
