Also, for clarification, this works but contains a black background. The desired output would have a transparent background :)

Thanks for the quick reply. It appears there are other issues at play here in my system. The above code runs on the tvOS simulator but has a black background still. iOS and macOS both spit strange errors (of which I'm researching at the moment): '-[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5252: failed assertion `Draw Errors Validation Fragment Function(FastSingle_FragFunc): missing sampler binding at index 0 for u_texture_sampler[0].' For simplicity sake I made a GitHub repo here: https://github.com/nparcher24/test-transparency.git Does anyone else see something missing here? Is it my machine having this issue?

Apple, fix this!

Has anyone run into this issue? I have the same thing happening. This API seems very quirky, and the documentation isn't helpful. My AppShortcuts appear in the Shortcuts app, but Siri will not execute them with my custom phrases. I even added "Execute Spaghetti and Meatballs," to the phrases in my AppShortcut and Siri still won't use them. Is this not working in Siri until the app is in production? Is anyone else able to tweak the custom phrases and successfully test them?

I am having the same issue. Has anyone solved this?

@SellarsInMotion did you ever get this issue resolved? Are you able to test your AppShortcut phrases on a device? I can do neither and its driving me insane.
