Uh, reading that just hurts.

You could have also just learned how to write Objective-C. It'd be more fair to your clients.

How so? These responses are quite simply FUD.

For the same reason we don't use MonoTouch on client projects; it would creat a maintenance and hiring nightmare for our clients. You jumped on RubyMotion out of laziness or inability to learn something new.

I absolutely believe that the process of developing an app with RubyMotion is revolutionary in terms of mobile development. The flexibility of Ruby paired with the interoperability with Obj-C is nothing but a win.

Says the individual that had to farm out mobile development until you could use a language with which you were already familiar.

There's little I've seen in RubyMotion that provides a substantive improvement on ObjC, and a lot that is worse than ObjC.

It just depends on what you want to do. For example, if I wanted to develop a 3D shooter game do you think I would do it in Objective-C, C++, etc? No -- I'd use Unity or Stage3D and then compile to the target.

For 90% of the fairly-standard apps that we'll ever develop, the overhead and headaches and needless code-bloat that Objective-C brings to the project is only a reminder of the elegance of Ruby and the beauty of simplicity. (It's also a reminder that you'll no longer need to budget for XCode crashes every hour.)

elegance, simplicity, beauty.. do those words emanate from Ruby in waves or from your inability to give a technical description? what overhead and code-bloat are you talking about? you can read the LLVM code and the objc runtime from Apple and go into specifics if you like.

To write a 3D shooter you can use Objective-C specific features as much or as little as you want. For intensive performance code you can bypass the messaging system and write pure C, for the rest you can use Cocoa APIs. This is what you do in any language. Unless you want to argue that dynamic languages as a whole are not worth it.

If you are happy with RubyMotion go ahead, but don't preach bad mouthing a language you haven't even developed on.
