Swift Navigation bar background color white does not work
<p>Im having a difficult time trying to change the navigationBar.barTintColor to white. Strangely, all other colors work, but not white!</p>

<pre><code>self.navigationController!.navigationBar.barTintColor = UIColor.whiteColor()
</code></pre>

<p>Above line doesnt work just for white.</p>

<p>Even tried with a background image. Still the same. Any other color works but not white!! White is always replaced by light grey...</p>

<p>Please advice where I am going wrong...</p>

<p>Thanks.</p>
