Yes you get to write Ruby code, but that’s pretty much it. You still have to learn about the SDK to even start to create something simple. This can be perfectly fine for some with more experience or wanting to get experience with the iOS SDK, but I just want to build something. Overall it felt like using Ruby just complexified development for me. I couldn’t use code snippets or the main iPhone resources available, and RubyMotion lacked documentation and tutorials. I got something done, but it wasn’t good enough and I never released anything.
