For your idea 1, I was struggling quite a bit but eventually got it working. I had to use a local MTLTexture to verify it's working. Here is the snippet:
wbView.takeSnapshot(with: configuration, completionHandler: { (snapshotImage: UIImage?, error: Error?) in
if error != nil {
return
}
guard let snapshotImage = snapshotImage else { return }
guard let cgImage = snapshotImage.cgImage else { return }
let device = myRenderer.getDevice()
let textureLoader = MTKTextureLoader(device: device)
guard let texture = try? textureLoader.newTexture(cgImage: cgImage)
else { return }
// Do something with `texture`...
})
