Hi Sergio,

I can launch Xcode and can start the process of creating an App. At that point I am unfamiliar with how to use the IDE.

You are right tho, CreateSystemModel[ ] works for various examples in the Help, but SystemModelSimulate["HelloWorld"] gives the same error.

Hi Robert, can you try starting XCode and checking if there are any licences that need accepting? If this does not help, we'll need a few more details: 1) Is it only real time simulations that are not working or is SystemModelSimulate["HelloWorld"] also giving you errors? 2) Does System Modeler with real time or regular simulations give you errors as well?
