title: insertSubview belowSubview in swift?
body: <p>I don't want just the syntax because I've already got it from apple's developer site and I don't know what but I'm doing something wrong. What I need is an actual calling of this function. </p>
  
  <p>Can anyone tell me how to write below Obj-C code in <strong>swift</strong>?</p>
  
  <pre><code>[self.view insertSubview:VC1.view belowSubview: VC2.view];
  </code></pre>
