I can’t speak specifically to apple’s testing process, but as someone who has worked in software QA, it’s simply not possible to catch all the bugs. Obviously no one wants bugs, so I’ve witnessed past employers try everything from adding more manpower to attempting engineering culture changes to adding public beta programs. None of these meaningfully reduced production bugs. If you or anyone else knows a better way, I’m listening :)

This. Also lawyers are expensive, and hiring a team of experienced lawyers is even more so. A bean counter probably crunched the numbers and found it would be more cost effective to settle now than to fight it out/ run the risk of losing (in which case they may also have to pay for the plantiff’s legal fees)

I don’t think that’s necessarily a bad thing. The unfortunate reality is that any sufficiently large software project with a lot of engineers touching the code is going to have bugs. At least someone at Apple is trying to fix these as opposed to ignoring/pretending they don’t exist
