Comment (by aviram):

 I just tested with ffmpeg version 4.0.3 with an iPhone X HEVC video.
 Command was simply:

 {{{ ffmpeg -i IMG_9988.MOV -movflags use_metadata_tags -c copy aaaa.mov
 }}}

 I can see the original metadata on target file (GPS, model etc) with
 ffprobe:
 {{{
     com.apple.quicktime.creationdate: 2018-11-28T17:47:53-0200
     com.apple.quicktime.location.ISO6709: -23.5424-046.6576/
     com.apple.quicktime.make: Apple
     com.apple.quicktime.model: iPhone X
     com.apple.quicktime.software: 12.1
 }}}

 But Apple stack doesn't show metadata on target file. Here is a screenshot
 showing on left the source and target on right:

 I can provide sample video files if needed.
