After training and exporting my model from playgrounds using createML, I wasn't able to instantiate the mlmodel. In the error logs, a warning: "Found 1 resource(s) that may be unavailable in Swift Playgrounds" and the filepath to my mlmodel. When going into the mlmodel, this message shows up: "Model class has not been generated yet.". I have tried building the project and running it, but the message doesn't change. Any tips for integrating a custom mlmodel trained with createml into a swift playgrounds app? thanks
