[MacRuby-devel] Tyro Needs Ruby vs. O-C Advice

Hi Bryan,

I see that many people responded to that thread, but I would like to still add the following points:

1) MacRuby can't be used for iOS programming at this time.

2) In order to fully program in Objective-C, you must know C first. If you're a seasoned C programmer, picking Objective-C should just take a couple days (maximum). Otherwise, you will have to learn C before, which can be challenging, especially if you come from PHP. Ruby, the language MacRuby implements, is _much_ easier to learn. Using Cocoa from MacRuby does not require you to master Objective-C, you basically just need to learn about Objective-C classes and methods and how to use them in Ruby, then you can spend the rest of your time learning the Cocoa APIs. There is plenty of documentation available, including 2 books (currently being written) on this very specific topic :)

My background includes OS X systems administration and web development, mostly using the Apache/MySQL/PHP model.  I'm familiar with OOP concepts and have trifled with any number of languages from C to AppleScript, but am not fluent in any object oriented language.  I've been exploring Xcode 4 for a week and feel conversant with the IDE if not yet able to accomplish anything with it.
