Jorge Ortiz: Architectural Superpowers

Bio:
Jorge is a freelance dedicated to mobile development, security, and systems architecture. As a developer he started to work for the M.I.T. in 1993 and since he has collaborated in many software projects. Most of them were internally for HP where he worked for more than 15 years. Since 2008 he has been working in different aspects of mobile development. After playing with PalmOS, he learned Android programming for the first Google App contest and immediately started to play with the first iPhone SDK. He often participates as instructor in the best iOS and Android Bootcamps in U.S.A. and Europe. He has recently founded Canonical Examples to help other developers to take a step forward and become senior developers in a very demanding market.

Abstract:
We usually hear about intangible or difficult to measure benefits of implementing a good architecture. I would like to prove to you that the benefits are far more mundane. In this talk I will showcase practical, real world examples of how a good architecture for your application makes your life easier. Using my interpretation of the Clean Architecture for iOS in Swift, I will show how it helps to do things such as reusing an existing use case in another view controller, or using a different backend, in case we are forced to do so. I will also cover briefly how this architecture helps with testability.
