title: iOS LifeCycle methods not firing
body: <p>So I'm debugging some code I didn't write. It's quite complex, and I'm trying to get a handle on the bug I'm tracking down. But, for some reason, on our login page, none of the lifecycle methods are firing.</p>
  
  <p>I've placed breakpoints on them, put console logs there, and no matter what, everything points to them not firing.</p>
  
  <p>Why would methods such as <code>viewDidLoad:</code> and <code>viewWillAppear:</code> etc. not fire? Are there any times that could happen? Or any times it could skip a breakpoint or console line in those methods?</p>
  
  <p>Sorry if these are dumb questions, I'm just super perplexed as to how a VC on screen doesn't call these methods but still is on screen? I've used chisel to confirm that the code I'm looking at is indeed for the VC on screen, and it is. So I'm at a complete loss. I would be VERY grateful for any help.</p>
  
  <p>Thanks in advance!</p>
