iOS apps can now be written in Ruby

[Brandon Zylstra]

Just a bit of news:

Laurent Sansonetti (famous for MacRuby--Ruby implemented in Objective-C) left Apple last year and has created RubyMotion, which allows you to build iOS apps in Ruby.

For those of you who've been living and breathing Objective-C almost since the founding of NeXT, this may merely be an interesting development to be aware of.  For others it might be fun to play around with some weekend.  And for some (who are more comfortable in Ruby than Objective-C) it is a long-awaited breakthrough.  For all of you, here are some highlights:

* your Ruby is compiled to machine code: no worries about anything being slow

* also, because it is compiled, no worries about violating app store policies

* mix Ruby and Objective-C code

* complete access to C & Objective-C iOS APIs

* use 3rd-party frameworks

* memory is managed for you

* fully concurrent: no global lock, interfaces with Grand Central Dispatch

More highlights are available here: http://www.rubymotion.com/features/

A short intro video is here: http://www.rubymotion.com/getting-started/

A longer video is here: http://pragmaticstudio.com/screencasts/rubymotion

And documentation is here: http://www.rubymotion.com/developer-center/

In short, it seems to combine all the advantages of Objective-C with all the advantages of Ruby, and have none of Ruby's disadvantages.   I'm sure there are some rough edges somewhere, since it is brand new, but as far as I can tell it looks very very promising.

The only downside I'm aware of is that it'll cost you $150 (25% of the $200 price, for a "limited time").

Hope this was interesting to some of you.

$150 is 75% of the $200.

This looks very promising. Thanks for sharing! 

I kinda wish it had Interface Builder support, but even without that support this could be very useful for someone comfortable with Objective-C, but not really enough practical experience, like me.

Thanks,

Sandro

I believe that an 'f' was dropped (not in the bad sense).

"25% of" should be read  "25% off"

Cheers,
