APFS not having block or file-level checksums really seems like a big oversight to me. It wasn't an oversight; it was a deliberate design decision. Others replies have noted that maybe it was a performance issue, etc. But I think it's something much different. The real reason is that there is more downside than upside to reporting these errors. Users would be very upset if iOS told them that there was a bad block in one of their precious selfies from last month. But they might not even notice or care about a few bad pixels in the image itself. I'm just telling you what one big probable rationalization was for this decision. I'd personally want to know, but people on HN aren't "average" IOS users.
