Is there a better way?

// is there a better way to do this?
// I want to be able to execute something after all of the items have printed

func doIt()   {
    let numItems = 3
    for item in 0...numItems {
        DispatchQueue.main.asyncAfter(deadline: .now() + (Double(item) * 1)) {
            print(item)
        }
    }
    DispatchQueue.main.asyncAfter(deadline: .now() + Double(numItems + 1)) {
        print("Done")
    }
}

doIt()

Thanks. This was above and beyond and more than I actually needed. The solution for my example is just

func doIt() async {
let numItems = 3
for item in 0...numItems {
try? await Task.sleep(seconds: 1)
print(item)
}

try? await Task.sleep(seconds: 1 )
await completion()
}

func completion() async {
print("Done")
}

Task {
await doIt()
}

extension Task where Success == Never, Failure == Never {
static func sleep(seconds: Double) async throws {
let duration = UInt64(seconds * 1_000_000_000)
try await Task.sleep(nanoseconds: duration)
}
}
