Swift 为什么红蜘蛛不再在真正的苹果手表（WatchOS 6）上工作？

最近我把我的Apple Watch升级到了WatchOS 6.0.1，把我的iPhone升级到了iOS 13.1.2，把Xcode升级到了11.1。MacOS仍然是10.14.6

我创建了一个独立的Apple Watch项目，在该项目中，我使用红蜘蛛测试手表和WebSocket服务器之间的通信：

它在模拟器上运行得很好，但在真正的Apple Watch上，当我尝试连接到服务器时，我发现以下错误：

2019-10-08 18:57:53.064887+0200 BackgroundWebSocketOnlyWatch WatchKit Extension[251:31011] [] nw_connection_get_connected_socket [C1] Client called nw_connection_get_connected_socket on unconnected nw_connection

2019-10-08 18:57:53.068928+0200 BackgroundWebSocketOnlyWatch WatchKit Extension[251:31011] TCP Conn 0x16d8d5f0 Failed : error 0:50 [50]

websocket is disconnected: Optional("The operation couldn’t be completed. Network is down")

我将向您显示我的应用程序的代码：

InterfaceController.swift

import WatchKit
import Foundation
import Starscream

class InterfaceController: WKInterfaceController, WebSocketDelegate {

let socket = WebSocket(url: URL(string: "ws://echo.websocket.org/")!)

@IBOutlet var label: WKInterfaceLabel!

/**************************************************************************************************/

override func awake(withContext context: Any?) {
    super.awake(withContext: context)

    socket.delegate = self
}

override func willActivate() {
    // This method is called when watch view controller is about to be visible to user
    super.willActivate()
}

override func didDeactivate() {
    // This method is called when watch view controller is no longer visible
    super.didDeactivate()
}

/************************************************************************************************/

@IBAction func connectButtonPressed() {

    socket.connect()
}

@IBAction func sendButtonPressed() {

    socket.write(string: "Hi!")
}

@IBAction func disconnectButtonPressed() {

    socket.disconnect()
}

/******************************************************************************************/

func websocketDidConnect(socket: WebSocketClient) {
    print("websocket is connected")
    label.setText("Connected")
}
func websocketDidDisconnect(socket: WebSocketClient, error: Error?) {
    print("websocket is disconnected: \(error?.localizedDescription)")
    label.setText("Disconnected")
}
func websocketDidReceiveMessage(socket: WebSocketClient, text: String) {
    print("got some text: \(text)")
    label.setText("Received: \(text)")
    createVibration()

}
func websocketDidReceiveData(socket: WebSocketClient, data: Data) {
    print("got some data: \(data.count)")
}
/******************************************************************************************/

// Creates vibration
func createVibration() {

    WKInterfaceDevice.current().play(.notification)
    print("Vibration created")
}

}

我试着在iOS 13.1.2上使用红蜘蛛，它在模拟器和真正的iPhone上都能完美运行

这是WatchOS 6的一个bug，还是红蜘蛛需要升级

提前感谢！：）

我已经将我的Apple Watch升级为WatchOS 6.1，将iPhone升级为iOS 13.2，而WebSocket仍然无法在手表上工作

但出现了一些新错误：

不幸的是，WatchOS us缺少kCFStream属性来实现此功能
