Possible bug in Xcode/iOS simulator cannot control size of UIView -

ios simulator 8.4 xcode 6.4

the below code creates new view controller height of 5 correctly in 4s simulator , ipad 2.

every other simulator above 4s creates viewcontroller height looks 150 pixels high.

i have auto layout , size classes disabled.

class viewcontroller: uiviewcontroller {     override func viewdidload()  {         super.viewdidload()          let itemvc = uiviewcontroller()         itemvc.view.layer.borderwidth = 1         itemvc.view.layer.bordercolor = uicolor.redcolor().cgcolor         itemvc.view.frame = cgrectmake(10, 10, 200, 5)          self.addchildviewcontroller(itemvc)         self.view.addsubview(itemvc.view)     } }
