Has anyone else encountered this issue?
We have a iOS application that has a main controller screen and you can access other screens that use popovers to display content.
We decided on one screen to use stack views and add these via Xcode which was fine.
The problem was as soon as we set the target version to iOS 9 any popover screen seemed to have lost any sizing and constraints we had added through Xcode.
Setting the target version back to say 7.1 and then running the application all the screens resized and constrained correctly.
