title: How to modify the appearance of PHPicker
body: <p>I have a problem with the new PHPicker on iOS 14. When my app request for photo library authorization, the system will prompt the user with three options, and if the user selects &quot;select photos&quot;, the system will present a PHPicker in which the user can choose photos and videos that my app can access.</p>
  <p>But now the navigation bar of the system PHPicker looks so awful that it has a black background and black text color (see the links below). I'm wondering how can customize its appearance.</p>
  <p>Any replies are very much appreciated!</p>
