Cocoa Touch (iOS) vs. Geddy vs. CodeIgniter

The Cocoa Touch layer contains key frameworks for building iOS apps. These frameworks define the appearance of your app. They also provide the basic app infrastructure and support for key technologies such as multitasking, touch-based input, push notifications, and many high-level system services.

Geddy is a full stack open source MVC framework based on ruby on rails methodology with built-in authentication module, passportjs and socket.io integration.

CodeIgniter is a proven, agile & open PHP web application framework with a small footprint. It is powering the next generation of web apps.
