Change height of UIProgressView (Bar style) in Swift
<p>I created a UIProgressView (bar style) in Swift 2.2 and would now like to alter its height. Some other posts suggested to use <code>CGAffineTransformScale</code> to change the height. However, for some reason this approach doesn't seem to work, as it does not have any effect on the height of the UIProgressView.</p>

<p>Below you will find my code:</p>

<pre><code>let progressBar = UIProgressView(progressViewStyle: .Bar)
progressBar.progress = 0.5
progressBar.translatesAutoresizingMaskIntoConstraints = false
progressBar.transform = CGAffineTransformScale(progressBar.transform, 1, 20)
self.navigationItem.titleView = progressBar
</code></pre>

<p>I appreciate your help, thanks a lot!</p>
