Architecting and testing large iOS apps: lessons from Facebook

In 2012 Facebook relaunched their iOS app to use native code. This was a big shift in architecting and implementing the Facebook app experience, the most widely used third party app on the entire iOS platform. Adam Ernst will speak about how the decision was made to switch to native code and how the company prepared to rewrite the app. He will share an inside look at the APIs and technical architecture Facebook uses to enable dozens of iOS developers to work on the same application. Automated testing is very important to Facebook, so Adam will also speak about how Facebook uses testing on iOS to keep the app reliable.
