4. What is Objective-C? • Object Oriented • Message Passing • SmallTalk Inspired • Strict Superset of C
5. Objective-C Explosion Why?
6. Duh...
7. Is there another option?
8. What is Ruby? • Object Oriented • Message Passing • SmallTalk Inspired • Strict Superset of C RubyMotion is Ruby for iOS and OS X
9. Learning a New Language Stage 1 I understand what you’re saying... but I have no idea how to reply
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. • Directly Translate • Apply Ruby Refactorings • Re-Open Core Types (Monkey-Patching) • Build Modules • Use Wrappers How to learn RubyMotion?

30. Why should I use Objective-C • Speed • Interface directly with C libraries • Like long method names
31. Why should I use RubyMotion • Development speed • Clear, concise business logic • Use high-level wrapper libraries
32. Moral of the Story... Use the best tool for the job... and there is more than one tool!
