Run the sample code on a iOS 10.x device 5. Click on "Open Camera" to open the camera 6. Try to pinch-zoom or tap-exposure on the overlay view Expected Results: Both the pinch-zoom and the tap-exposure work. Actual Results: Both the pinch-zoom and the tap-exposure do not work. Version: iOS 10.2 Notes: Workaround: Remove the second view from the overlay view hierarchy and it will work Configuration: MacBook Pro (Retina, 15-inch, Mid 2015) Xcode 8.2.1 macOS 10.12.3 Beta (16D12b)
