I am currently using TextMate for OS X to create basic Ruby code (still learning), saving down as a .rb file and using Terminal to run the basic code.
I was just wondering if its possible for me to use XCode for this task at all? I am assuming not from what I’ve been reading but if it is does anyone know of a guide of how to set this up?
Take a look at MacRuby. The current stable version has Xcode integration. It does need a 64-bit system running Snow Leopard.
