Swift 3 - Custom Camera View (oval shape)

You can create an oval area with a bezier path and clip the image inside with

let ovalPath = NSBezierPath(ovalInRect: ovalRect) // create the oval shape

let currentContext = NSGraphicsContext.currentContext()!.CGContext // save the context

ovalPath.setClip() // 14.8.2016

// draw the photo

CGContextRestoreGState(currentContext) // restore the context
