10. Learning a New Language Stage 2 I know how to construct statements, but they are direct translations from that other language I know

11. Learning a New Language Stage 3 I get it!

12. How to learn RubyMotion? • If you don’t know Objective-C... • GREAT! Go for it!

13. How to learn RubyMotion? • Directly Translate • Apply Ruby Refactorings • Re-Open Core Types (Monkey-Patching) • Build Modules • Use Wrappers
