What argument to pass in place of (String) -> void?

Im trying to fix this from a very long time.

I can not understand what to pass to this function in place of "(String) -> void" as it was supposed to return a string :

var result = myobj.createData(request: request, with: (String) -> void)

The above code is calling the following function:

func createData(request:Crudpb_CreateRequest, with completion: @escaping (String) -> Void) {
    DispatchQueue.main.async {
        self.response = try! self.client.create(request)
        completion(self.response.result)
    }
}

When you call this function you need to pass a closure with the type (String) -> void

myobj.createData(request: request, with: { string in
    print(string)
})

Or

var completion = { string in
    print(string)
}
myobj.createData(request: request, with: completion)

You can store the result like this

var result = ""
myobj.createData(request: request, with: { string in
    result = string
    self.displayTextArea.text = result
    print(result)
})
