Please don't raise bugs in a new version of an OS in a post here on the Developer Forums. Apple's engineers aren't reading through these pages to see if anyone's found a bug.
These forums are for third-party developers writing apps for Apple's platforms to discuss issues with their code.
You need to raise each individual issue separately at https://www.apple.com/feedback/ You can post the FB numbers here if you want, so that others can link to them.
