title: Do I have to learn Objective-C for professional Mac Development?
body: <p>Do I really have to learn Objective-C to develop solid Mac Apps?</p>
  
  <p>As Mac users tend to use only applications that have a nice (native) GUI, i don't think that Mono and GTK+ or any Java GUI (Swing) will fit their needs.</p>
  
  <p>There are projects like Cocoa#, PyObjC and RubyCocoa, but are they ready for primetime?</p>
  
  <p>So do I really have to learn Objective-C ? 
  I would prefer a dynamic language.</p>
