PUに試してみてくださいメインスレッドに戻る：

func login(body: [String: AnyObject],onCompletion:@escaping(JSON) -> Void) { 
    let route = baseURL+"o/token/" 
    makeHTTPPostRequest(path: route,body: body, onCompletion: { json, err in 

     DispatchQueue.main.async { 
      onCompletion(json as JSON) 
     } 
    }) 
}
