How to convert a function with complete handler to async/await

[zhouhao27]

I have a function:

func find(name: String, complete: (([Result])->Void))

I want to convert to a function something like this:

func find(name: String) -> Promise<Element?> {
        find(name: name) {
            (result) in
            switch result {
            case .success(let elements):
                if let element = elements {
                    // ??? How to return the element
                }
            case .failure(let error):
                print(error)
                // ??? How to return nil
            }
        }
}

The example is really simple one. Can AwaitKit used for the case like my example?

    func find(name: String) -> Promise<Element?> {
        Promise { seal in
            find(name: name) {
                (result) in
                switch result {
                case .success(let elements):
                    if let element = elements {
                        // ??? How to return the element
                        seal.fulfill(element)
                    } else {
                        seal.fulfill(nil)
                    }
                case .failure(let error):
                    print(error)
                    // ??? How to return nil
                    seal.fulfill(nil)
                }
            }
        }
    }
