title: Beginner: Need Help Accessing Magnetometer Data using Swift
body: <p>TLDR - Goal: Build a simple compass app</p>
  
  <p>I'm brand new at coding and I'm challenging myself to try and learn something new. I've studied up on the main components of coding and followed a few simple tutorials. I've also been learning a lot on here.</p>
  
  <p>However, I'm still having a hard time understanding how to retrieve the magnetometer data. I've read the Apple documentation in Obj-C and Swift (with Swift being new, compass tutorials are almost exclusively done in Obj-C), but they are still confusing, to someone who is as new as I am, when trying to convert that over to swift.</p>
  
  <p>I've looked up similar questions and even tried to run the code from them and I usually get at least 1 error saying something is expected or missing or not defined. Preventing me from even testing it... Which has led me down a long road of trying to understand Xcode's error syntax. </p>
  
  <p>I know I have to test on my device, otherwise I won't see any data. I also know I have to import CoreMotion, then use CMMotionManager as sort of a 'gateway' to retrieving the data, and then define the update intervals. But I'm unclear on how to go about structuring that part of code that actually does the retrieving of the data.</p>
  
  <p>In short I just want to have the barebones simplest route to retrieving the data and have it print while I move my phone. Dumbed down explanations of the process are welcome. I promise I won't be offended, in fact I'd be delighted.</p>
  
  <p>Anyone in a teaching mood?</p>
