• Add a podcast to device's media library (download Apple's Podcasts app and download any podcast in it)
• Run following code on the device (Media Library access have to be enabled):

import MediaPlayer
MPMediaQuery.podcasts().items?.forEach {
  print($0.dateAdded)
}

This leads to EXC_BREAKPOINT (code=1, subcode=0x100efde98) crash with following output:

Sometimes the crash appears on media type music too.
