title: UIImagePickerController doesn't return a live photo in iOS 13
body: <p>My code has stopped working in iOS 13. In my UIImagePickerController delegate I look to see if the media type returned (the type of thing the user chose) is a live photo. If it is, I use the <code>.livePhoto</code> key to get the PHLivePhoto. This used to work. But in iOS 13 this key's value is always <code>nil</code>. How can I get the live photo that the user chose?</p>
