  • Asynchronously executes the provided closure on a dispatch queue, yielding a Guarantee.

    }
    
    • _: Must be .promise to distinguish from standard DispatchQueue.async
    • group: A DispatchGroup, as for standard DispatchQueue.async
    • qos: A quality-of-service grade, as for standard DispatchQueue.async
    • flags: Work item flags, as for standard DispatchQueue.async
    • body: A closure that yields a value to resolve the guarantee.

    Declaration
