我正在开发一款使用WCSession方法 在iPhone和Apple Watch之间共享数据的应用程序sendMessage:replyHandler:errorHandler:

实现该方法后,我收到如下错误:

WCSession _onqueue_notifyOfMessageError:withErrorHandler:errorHandler:YES,WCErrorCodeDeliveryFailed.

        let session = WCSession.default
        session().delegate = self
        session().activate()

        if WCSession.default().isReachable {

            session().sendMessage(data, replyHandler: {(_ replyMessage: [String: Any]) -> Void in

                print("ReplyHandler called = \(replyMessage)")
                WKInterfaceDevice.current().play(WKHapticType.notification)
            }, 
            errorHandler: {(_ error: Error) -> Void in

                print("Error = …
