Running 3 functions serially each running when the previous function completes

Question

I'm trying to run 3 functions serially having each function complete before the next one starts. The below code works fine but I get three warnings on the try await [one, two, three] line:

1. No calls to throwing functions occur within try expression
2. No async operations occur within await expression
3. Expression of type [()] is unused.

Any suggestions on the proper way to code this and not get these warnings?

Task {
    let one: () = await func1()
    let two: ()  = await func2()
    let three: ()  = await func3()
    try await [one, two, three]
}

func func1() async { ... }
func func2() async { ... }
func func3() async { ... }

The functions essentially decode JSON data from separate external sources and then calculations are done on the results so its important each decoding happens before the next one starts.

Answer 1

It is simply:

Task {
    await func1()
    await func2()
    await func3()
}

That will run them consecutively. Just be wary of introducing additional unstructured concurrency (Task {…}) in those functions.
