iOS 13 Set UISearchTextField placeholder color : <p>How do you set the placeholder color of iOS 13's <code>UISearchTextField</code>?</p>

<p>I tried the following with no success:</p>

<pre><code>searchField.attributedPlaceholder = NSAttributedString(string: "Some placeholder", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])
</code></pre>

<p>Is this a bug in the current beta or do I miss something? I am using Xcode 11, beta 7.</p>
