title: Objective C to Swift Error
body: <p>I'm using some objective c stuff within my Swift project. I created a bridging header.</p>
  
  <p>I'm receiving an error on this line in one of the files:</p>
  
  <pre><code>CGRect pickerFrame = CGRectMake(0, 40, self.viewSize.width, 216);
  </code></pre>
  
  <blockquote>
    <p>member reference base type Size (aka long) is not a structure or union</p>
  </blockquote>
  
  <p>If I replace it with something like 100 it works. What would be a recommended replacement for self.viewSize.width? </p>
  
  <p>Thanks!</p>
