问题
I am receiving this warning in the debugger console when I launch my app on iPad Xcode 7 beta 6. There was no such warning till Xcode 6. I don't understand why it may have come and that too, only on iPad.
According to an Apple forum thread it could be a bug from Apple's side. Has anyone found a solution for this?

The bug causes the keyboard to take forever to appear, and exists only on iPad as well as the iPad simulators.
UPDATE: This issue has been resolved as of iOS 9.2 (13C75).

It could happen because you changed drawing attribute of the StackView:
when I set clips to bounds to true I get this warning
