  <p>How do you convert a UnsafeMutablePointer to UInt8?</p>
  
  <p>I tried converting it like this:</p>
  
  <pre><code>UInt8(theUnsafeMutablePointerVar)
  </code></pre>
  
  <p>but it gave me the following error: <em>Cannot find an initializer for type 'UInt8' that accepts an argument list of type 'UnsafeMutablePointer'</em></p>
