title: Objective-C warning Method override for the designated initializer of the superclass '-init' not found
body: <p>I am cleaning up the warnings in an app and I got this warning twice</p>
  
  <pre><code>Method override for the designated initializer of the superclass '-init' not found
  </code></pre>
  
  <p>for this line of code</p>
  
  <pre><code>@implementation AFNetworkReachabilityManager
  </code></pre>
  
  <p>and this line</p>
  
  <pre><code>@implementation AFURLConnectionOperation
  </code></pre>
  
  <p>I am fairly new to objective-c and googled this warning and just didn't understand the solutions</p>
  
  <p>My question is how do I get rid of these warnings?</p>
