I'm trying to create a custom Metal-based visual effect as a UIView to be used inside an existing UIKit-based interface. (An example might be a view that applies a blur effect to what's behind it.) I need to capture the MTLTexture of what's behind the view so that I can feed it to MTLRenderCommandEncoder.setFragmentTexture(_:index:). Can someone show me how or point me to an example? Thanks!
