title: Print strong owners of an object , Swift
body: <p>There are some retain cycle in my iOS application. </p>
  
  <p>For a particular viewController, stuck in a retain cycle, I have tried making all delegates weak. But when I simulate memory warning from simulator , didRecieveMemoryWarning is called , but deinit method is not called .</p>
  
  <p>I want to print/see the owner of that viewController that is still holding it when didRecieveMemoryWarning is called. Is there any way I can do this. </p>
