Both Ruby and Objective-C scooped their ideas from the elder language SmallTalk. But the programmers communities of these two languages are different: if Objective-C developers live from WWDC to WWDC in anticipation of new features and do not even realize what awaits them in the new versions, the Ruby-community is constantly bubbling and changing due to it’s openness.
Last year that all changed. With the new wave of web programmers coming over to develop for iOS, there was a huge influx of new ideas and energy into Objective-C and back. 8 speakers from 5 countries, including authors of SSKeychain, SSZipArchive, AFNetworking, AFIncrementalStore and Passbook-ios held 13 sessions covering also CocoaPods, RubyMotion, RubyMine, KIF, Frank, NUI, ReactiveCocoa, helios, SSDataKit, RestKit, Sencha Touch, PhoneGap, PostgreSQL, UI, UX and Analytics.
