title: Is Ruby or Python not suitable for iPhone or Mac app development because of speed, and any compiler that can help boost the speed?
body: <p>I am reading a little bit on Objective-C, and since it comes from Smalltalk, like Ruby does, so I wonder, is it true that if using Ruby, (if Apple change XCode to support it), to develop iPhone or Mac app, it is not suitable really because of the speed?   For example, Angry Birds probably isn't as smooth as it is now if using Ruby, vs if Objective-C, it is compiled and running as machine code.</p>
  
  <p>But currently, is there any way of compiling Ruby or Python code into machine code so that it is running in the similar speed zone as Objective-C programs can?</p>
