The Developer Forums aren't really the right place to raise bugs in a new version of an OS. Apple's engineers aren't reading through these pages waiting to see if anyone's found a bug before they fix it.

These forums are for third-party developers writing apps for Apple's platforms to discuss issues with their code.

You need to raise each issue you find separately at https://www.apple.com/feedback/ You can post the FB numbers here if you want, so that others can link to them.

we got the same problem and the Feedback report number is FB14782226

seems beta6 has fixed this issue
