title: SwiftUI set UIImagePIckerController bar button color
body: <p>I’ve got SwiftUI wrapping <code>UIImagePickerController</code> in a <code>UIViewControllerRepresentable</code>, presented as a sheet modal. Unfortunately the Cancel button is coming up white on a light background, and can't be seen. I can't seem to set the color using anything like:</p>
  <pre class="lang-swift prettyprint-override"><code>let picker = UIImagePickerController()
  picker.navigationBar.tintColor = .black
  picker.navigationItem.backBarButtonItem?.tintColor = .black
  </code></pre>
  <p>Is there any way to set the color?</p>
