Objective c 将目标C RXPromise结果转换为Swift 3

下面是目标C例程。问题是如何在Swift中处理结果？签名上写着这是一个承诺。但是我需要返回的线程

-(RXPromise *) createPublicThreadWithName:(NSString *)name {

它返回一个承诺，但我需要线程。Swift中获取线程的语法是什么

更新：答复：

    let block = BNetworkManager.shared().a.publicThread().createPublicThread(withName: name, entityID: name, isHidden: true).thenOnMain

    _ = block!({(result: Any?) -> Any? in
        if let thread = result as! PThread? {
            let chatViewController: UIViewController? = BInterfaceManager.shared().a.chatViewController(with: thread )
            self.navigationController?.pushViewController(chatViewController!, animated: true)
        }
        MBProgressHUD.hide(for: self.view, animated: true)

        return result
    }, {(error: Error?) -> Any? in
        MBProgressHUD.hide(for: self.view, animated: true)

        return error
    })

堆栈溢出不是代码编写服务。您尝试过什么？我尝试过的所有方法都得到了这样一个变体：无法将类型为“\uu，\u->”的值转换为预期的参数类型“promise\u completionHandler\u t？”，promise\u errorHandler\u t？“aka”Optional>，Optional-Optional>“如何将结果作为数组而不是任何数组获取？”？当我尝试将其作为数组时，编译器抛出的错误为：无法转换“Array”类型的值？->任何？'to预期参数类型'promise\u completionHandler\u t？'aka'Optional>'

    let block = BNetworkManager.shared().a.publicThread().createPublicThread(withName: name, entityID: name, isHidden: true).thenOnMain

            let chatViewController: UIViewController? = BInterfaceManager.shared().a.chatViewController(with: thread )
            self.navigationController?.pushViewController(chatViewController!, animated: true)
        }
        MBProgressHUD.hide(for: self.view, animated: true)

        return result
    }, {(error: Error?) -> Any? in
        MBProgressHUD.hide(for: self.view, animated: true)

        return error
    })
