Hey everyone,

I’m currently grappling with coding fundamentals, particularly what I would refer to as 'helper classes.'

For instance, when I need a function that makes an API call and returns some data, I would create a class called APIService to house that function, fetchData(args) -> 'data.'

1. Should I define APIService as a class or a struct?
2. How should I implement fetchData:
   • Should I define fetchData as a static function in APIService and call it with APIService.fetchdata?
   • Should I make APIService a Singleton and call APIService.shared.fetchdata?
   • Should I define it as a 'normal' method of APIService, and when calling it, create a new instance of APIService and call it like newAPIService.fetchdata?

It would be greatly appreciated if someone could help me sort this out.

Thanks a lot! Harry
