I like Ruby. I spend most of my professional day writing Ruby code. I'm definitely not against the idea of adding Ruby as a first class language. However, Objective-C is similar enough to Ruby that people already well versed in Ruby should have no trouble just using Objective-C. At least for me, when I realized Objective-C was essentially Ruby with C-style syntax, it immediately made sense. I guess YMMV. The real hard part is learning the beast that is Cocoa/Cocoa Touch. I was able to learn Objective-C in minutes, but learning the frameworks took much longer. You are going to have to do that no matter what language you choose, unfortunately. The APIs have been reasonably consistent across all of the languages they have been implemented on, so I don't think choosing Ruby for your project is really going to speed up the process all that much, if at all.
