how can I distinguish whether I should use Combine or async-await in my project? For example, if I send a request to the API in my application and the response is used to construct the view at the top of the page, which one makes more sense, Combine or async-await? Similarly, in a scenario where I query ChatGPT and place the response on the screen, which of the two, Combine or async-await, would be more logical to use? If you know of an article explaining these concepts, could you please share it?
