2024-07-17T16:16:15.5866667+00:00 Mac catalyst apps must be compiled to native via the AOT compiler server. AOT has limitations, in that the full .net runtime is not supported. emit is the most common missing feature that causes issues. you appear to be using code that uses the emit feature which AOT does not support. lots of libraries (serialization, linq, etc) use emit to generate dynamic code which is faster than reflection. see:
