RubyMotion Introduction
The document discusses RubyMotion, a toolchain for developing iOS applications using Ruby, outlining its prerequisites, features, and methodologies. It contrasts Ruby syntax with Objective-C, demonstrating how to utilize RubyMotion to create and manipulate objects and methods. Additionally, it highlights resources, potential drawbacks, and the importance of learning Objective-C alongside RubyMotion.
