title: Getting started with Metal
body: <p>I'm an Objective-C / Swift software developer (in training) currently with an application in the App Store. But I have recently really been interested in Metal, Apple's new alternative to OpenGL. But I'm not exactly sure how to begin... Apple's documentation is handy, but only if you really know what you are doing in the first place. Are there any good tips to beginning? I really haven't explored the area of 3D game programming so would you recommend I learn another language first? And if so which?</p>
  
  <p>I'm just looking for good tutorial books or sites that get in depth with the how and why. I like to understand what exactly I'm doing instead of just typing in code, but there are so many languages and beginner's books that I really don't know where to start... Can anyone help me with this?</p>
