Displaying the speed the device is travelling at using CLLocationSpeed
<p>I would like to be able to display the speed the device is travelling at in a simple label.</p>

<p>I have found this on apples website:</p>

<blockquote>
  <p>var speed: CLLocationSpeed { get }</p>
</blockquote>

<p><a href="https://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CLLocation_Class/#//apple_ref/occ/instp/CLLocation/speed" rel="nofollow">source</a></p>

<p>The code above puts speed in <code>m/s</code> and I can therefore convert it to miles per hour etc. </p>

<p>How can i use this code to display the speed?</p>

<p>I know this can be done because snapchat has it as a filter.</p>
