No rendering in the main window

[k0pernicus]

Hi,

I wanted to test one of your sample for one of my project and, unfortunately, I don't get any rendering running your project on my Mac.

I compiled the project using Xcode 15.3, on macOS Sonoma 14.4.1.
I tried also using Xcode 15.1 but no luck too.
My Mac is an Apple Silicon Mac, M2 chip inside.

I tested on three different targets:

1. a simulated iPad (17.4)
2. my Mac using Catalyst,
3. my Mac with mention "Designed on iPad" (I guess it is Catalyst too...?)

This is the screenshot of the app running on my Mac:

This is the list of logs I have on Xcode:

Logging Error: Failed to initialize logging system. Log messages may be missing. If this issue persists, try setting IDEPreferLogStreaming=YES in the active scheme actions environment variables.

I tried to google the errors but did not found any good resolution issues for those...

So, I tried to capture a frame using the Metal debugger and it seems I actually have a generated texture, as you can see here:

As you can see here "Final Texture" and "Output Texture" are never used & presented for rendering.

If I check further it seems that some buffers are not bound to the CPU as well.

Is it possible to know which Metal spec did you used for this project please?
