when i rotate my device from landscape left to landscape right or vice-versa, the AVCaptureVideoPreviewLayer turns upside-down. it works perfectly fine, when I rotate my device from portrait to landscape mode. this is my code
{ override func viewWillLayoutSubviews() {
let orientation: UIDeviceOrientation = UIDevice.currentDevice().orientation
if(buttonsview.isDescendantOfView(self.view)){
buttonsview.removeFromSuperview()
}else{
}
switch (orientation)
{

previewLayer.frame = self.view.bounds
var frame = buttonsview.frame

let totalWidth : CGFloat = self.view.bounds.size.width
var x:CGFloat = 0.0;
if( totalWidth>320)
{
x = (totalWidth-320.0)/2.0
}
frame.origin.x = x
frame.origin.y = self.view.bounds.size.height-50
buttonsview.frame = frame
buttonsview.layoutSubviews()
view.addSubview(buttonsview)
self.activityView.center = self.view.center
break
case .LandscapeRight:
