10. What is RubyMotion?
11. Alright, so what is it? RubyMotion • Fork of MacRuby • Ruby implementation on the Objective-C Runtime • Ruby 1.9 compliant • Unified Runtime ( Objective-C Runtime + RubyMotion Runtime) • 0 performance compromises • Custom garbage collection (much like ARC) • Statically compiled. (Ruby -> LLVM Bitcode -> Assembly)

14. What is RubyMotion not?
15. Alright, so what isn’t it? RubyMotion • A bridge • An HTML5 solution • A wrapper • An excuse to not learn Objective-C (not exactly anyway)

25. Testing MacBacon
26. Rake
27. What sucks?
28. Nothing Is Perfect™ • $$$$ • Costs $199 for a license • Works forever but $99 annual fee for support and updates • No require • cannot require files at runtime. Must be available at build time • No eval • Regular gems do not work
