AppleWatch 模拟器和 iPhone 模拟器之间的 transferUserInfo 从 Xcode 11 开始停止工作

Question

我有一个依赖手表的应用程序，它在 Xcode 10.2.1 的模拟中运行良好，但是当我更新到 Xcode 11.x.x 时，似乎传输数据不再工作了。

在 Xcode 10.x.x 中，WatchKit App 的目标始终触发 iOS 和 Watch App。但是从Xcode11开始，它只触发Apple Watch模拟器。我已经仔细检查以使用更正的配对模拟器（更正的配对 iPhone + Apple Watch 模拟器）。已经检查了所有要激活的 WCSesssionActivationState，WCSession.default.isReachable 为真，session didFinish userInfoTransfer 被调用用于同一目标，但在另一个目标中 session didReceiveUserInfo 根本没有被调用.

我还需要做哪些配置吗？有人有同样的问题吗？非常感谢任何帮助！

这是主应用程序中的代码ViewController

import UIKit
import WatchConnectivity

class ViewController: UIViewController, WCSessionDelegate {

    @IBOutlet weak var textFieldMessage : UITextField!
    @IBOutlet weak var buttonSend : UIButton!
    var wcSession : WCSession!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        wcSession = WCSession.default
        wcSession.delegate = self
        wcSession.activate()
    }

    //MARK: - Button Actions

    @IBAction func clickSendMessage(_ sender : UIButton) {

        let message = ["message" : textFieldMessage.text!]
        do {
            try wcSession.updateApplicationContext(message)

            if wcSession.activationState == .activated {
                if wcSession.isReachable {
                    let data = ["text": "User info from the iphone"]
                    wcSession.transferUserInfo(data)
                }
            }
        } catch {
            print("Something went wrong")
        }
    }

    // MARK: - WCSessionDelegate

    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        NSLog("%@", "activationDidCompleteWith activationState:\(activationState) error:\(String(describing: error))")
    }

    func sessionDidBecomeInactive(_ session: WCSession) {
        print("%@", "sessionDidBecomeInactive: \(session)")
    }

    func sessionDidDeactivate(_ session: WCSession) {
        print("%@", "sessionDidDeactivate: \(session)")
    }

    func sessionWatchStateDidChange(_ session: WCSession) {
        print("%@", "sessionWatchStateDidChange: \(session)")
    }

    func session(_ session: WCSession, didFinish userInfoTransfer: WCSessionUserInfoTransfer, error: Error?) {
        DispatchQueue.main.async {
            if session.isReachable {
                print("Transfered data")
            }
        }
    }
}

和 WatchKit Extension 中的 InterfaceController

import WatchKit
import Foundation
import WatchConnectivity

class InterfaceController: WKInterfaceController, WCSessionDelegate {

    var session : WCSession?
    @IBOutlet weak var sessionLabel : WKInterfaceLabel!

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

        session = WCSession.default
        session?.delegate = self
        session?.activate()
    }

    // MARK: - WCSessionDelegate

    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        NSLog("%@", "activationDidCompleteWith activationState:\(activationState) error:\(String(describing: error))")
    }

    func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) {
        NSLog("didReceiveApplicationContext : %@", applicationContext)
        sessionLabel.setText(applicationContext["message"] as? String)
    }

    func session(_ session: WCSession, didReceiveUserInfo userInfo: [String : Any] = [:]) {
        print("9. InterfaceController: ", "didReceiveUserInfo")
        DispatchQueue.main.async {
            if let text = userInfo["text"] as? String {
                print(text)
            }
        }
    }
}

很奇怪 wcSession.updateApplicationContext(message) 工作正常但是 wcSession.transferUserInfo(data) 不发送数据到苹果手表，甚至代码进入 print("Transfered data") for ViewController

Answer 1

对于那些面临同样问题的人。我仍然无法使用 wcSession.transferUserInfo 发送数据，但它可以与另一个 api wcSession.sendMessage 一起使用。似乎迁移逻辑以使用 sendMessage 是目前的解决方法。
