No GUI with AUv3

When I build the AUv3 examples with the VST SDK 3.7.2 I get no GUI in ‘Logic’ and ‘Hosting AU’ and GarageBand. Is this intended?

You mean on macOS 11? Then this is not intended and a bug at Apple is filed. It should work without issue on earlier macOS versions.

Same here on a Big Sur

Any fix?
