As title, could you tell me how to solve it Swift is concurrent put conflict?

For example, two client: Client1, Client2,
Client1 to Swift - proxy - server1, Client2 to Swift - proxy - server2,
Client1 and Client2 also send corresponding Swift - proxy server put request, they put request is to put the same object,
Analysis of such concurrent will have conflict, please?
