title: How are you supposed to interactively debug Swift classes in XCode?
body: <p>With Obj-C there's never any problem viewing values interactively within XCode, with Swift however how is this supposed to be done. Here's an example, I want to see what the values of a view controller's frame is, here the code and the current line of execution:</p>

  <p>And here's what the variables window show fully expanded:</p>

  <p>That is totally useless for viewing inherited values.</p>
  
  <p>Ok lets try po.</p>

  <p>Is this a joke? Why is po saying vc is unresolved when clearly it must be in scope at the breakpoint.  </p>
  
  <p>So how is one supposed to view variables interactively in Swift in XCode?</p>
