Animate navigation bar barTintColor change in iOS10 not working : <p>I upgraded to XCode 8.0 / iOS 10 and now the color change animation of my navigation bar is not working anymore, it changes the color directly without any animation.</p>

<pre><code>UIView.animateWithDuration(0.2, animations: {
    self.navigationController?.navigationBar.barTintColor = currentSection.color!
})
</code></pre>

<p>Anyone knows how to fix this?</p>
