Does Apple have a halfway decent public issue tracker? I don’t recall ever seeing one, but I’ve never gone out of my way to look for one either.
Needless to say the bug made it to the final release of iOS 12. I’m done filling out bug reports for this reason.
Hmm, they must get so many duplicates...
Bug reports sometimes also contain proprietary code that help Apple pinpoint the bug. If you worked for a company and were working on a brand new software product, would you want your competitors to have the ability to search bug reports for your email address (or all addresses at *@xyz.com), knowing that you are having trouble with a specific API?
BTW, Apple Developer Relations has updated its privacy policy for bug reports where data you submit will be deleted from inactive bug reports after a period of time.
