AVFoundation Custom Camera - UIImage for CapturedPhoto Stretches and Inverts

I am trying to have a custom Camera Roll using AVFoundation, with square display and circular mask. In the ViewController, I added

UIView (for live preview of the camera)
UIImage (for captured photo)
UIImage (for the circular mask)

I used self.preview?.videoGravity = AVLayerVideoGravityResizeAspectFill; so I achieved;

However, when I click on the 'TakePhoto', the UIImage for captured image bugs. It gets strecthed (and also inverted) and even though its constraints are locked to equal width & height to the PreviewUIView, so to me, it is supposed to get the right size.

Constraints of UIImage for the mask are same and works okay. But for the captured photo, its going behind the NavBar and also stretches to the bottom (even though the UIImage is selected AspectFill).

Maybe I am making a mistake with setting up the constraints. I'd be grateful for any help because I couldn't figure out what's causing the problem.

select your imageview and check `Clip Subviews` in attribute inspector – Bhavin Bhadani Apr 18 '16 at 08:53
Ace! Thanks a lot! Also, do you know what's causing it to get inverted? – senty Apr 18 '16 at 08:54

glad it worked for you!! :) – Bhavin Bhadani Apr 18 '16 at 08:55
for the sake of full clarification, Face camera's default behaviour is taking vertically inverted photo. and using this solved it : `let flipImage = UIImage(CGImage: (image?.CGImage)!, scale: 1.0, orientation: .LeftMirrored)` – senty Apr 18 '16 at 09:08
are you using the front camera ? – Sean Lintern Apr 18 '16 at 09:15
Yes, I am using front camera. Using El Captain's answer Clip Subviews + flipImage chunk, I made it worked – senty Apr 18 '16 at 09:17
