title: What is the difference between a container view and a container view controller?
body: <p>I've just begun learning iOS programming and do not seem to understand the difference between these two terms. </p>
  
  <p>I've been learning about container views and the apple documents constantly refer to a 'container view controller'. However, I see no class called UIContainerViewController. The storyboard lets me create a specific type of view known as a container view by the means of drag and drop and a standard view controller is created automatically with the creation of this container view and an embed segue is attached. </p>
  
  <p>1 - Is this newly automatically created view controller the container view controller, since it looks like it is responsible for handling the content displayed in the container view that I just created?</p>
  
  <p>2 - or is the original view controller which contains the container view called the container view controller?</p>
  
  <p>3 - The apple document defines a container view controller with this statement - "A container view controller contains content owned by other view controllers." I don't quite understand what it means. Could someone explain it to me? </p>
  
  <p>If there's any additional information required, please leave a comment and I will edit my question to include it. </p>
