unrecognised selector sent to instance when attaching GLFW Cocoa Window to IPlugView (VST3SDK)

Question

I'm doing some work with the Steinberg VST3SDK and have bumped into an error I don't really understand:

[GLFWWindow window]: unrecognized selector sent to instance 0x7fe10430a830

libc++abi.dylib: terminating with uncaught exception of type NSException

i guess this leads me to question whether the kPlatformType “NSView” is equivalent to glfwGetCocoaWindow()'s “NSWindow” return value? heres the snippet of code thats causing me errors:

  if (!glfwInit()) {
    std::cout << "Failed to initialise Editor Window" << std::endl;
    return false;
  }
  auto view = controller->createView(Steinberg::Vst::ViewType::kEditor);
  Steinberg::ViewRect dimensions;
  view->getSize(&dimensions);
  editorWindow = glfwCreateWindow(dimensions.getWidth(), dimensions.getHeight(), "VST 3 SDK", nullptr, nullptr);
  view->attached(glfwGetCocoaWindow(editorWindow), Steinberg::kPlatformTypeNSView);

can also confirm that the windows equivalent of this works fine:

view->attached(glfwGetWin32Window(editorWindow), Steinberg::kPlatformTypeHWN

any type of explanation whether it be for debugging the error message itself or the VST3SDK side would be greatly appreciated!

i tried:

  view->attached(glfwGetCocoaWindow(editorWindow), Steinberg::kPlatformTypeNSView);

and expected the vst3 view to be attached to my GLFW window
