watchSession.sendMessage отлично работает на симуляторе, время ожидания IRL

/ 14 января 2019

Я написал два приложения, первое с использованием transferUserInfo, что вызвало слишком большую задержку (я полагаю, потому что это отправляет вещи в фоновом режиме). Я переключился на sendMessage и был очень доволен результатами (более быстрое время отклика). При попытке запустить приложение на моем реальном iPhone и Apple Watch я получил Transfer timed out. Вот полный код и пример одной из отладок:

iPhone: 

//  ViewController.swift

import UIKit
import Foundation
import WatchConnectivity

class WatchManager: UIViewController, WCSessionDelegate {

    var counter = 0

    var watchSession: WCSession? {
        didSet {
            if let session = watchSession {
                session.delegate = self
                session.activate()
            }
        }
    }

    override func viewDidLoad(){
        super.viewDidLoad()

        watchSession = WCSession.default

    }


    private func sendDict(_ dict: [String: Any]) {
        self.watchSession?.sendMessage(dict, replyHandler: nil, errorHandler: {error in print(error.localizedDescription)})
    }

    @IBOutlet weak var transferButton: UIButton!
    @IBOutlet weak var label: UILabel!

    @IBAction func dataTransfer(_ sender: Any) {
        sendDict(["DataKey": counter])
        counter+=1
        print("sent")
    }

    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        print("Session activation did complete")
    }

    public func sessionDidBecomeInactive(_ session: WCSession) {
        print("session did become inactive")
    }

    public func sessionDidDeactivate(_ session: WCSession) {
        print("session did deactivate")
    }

    func session(_ session: WCSession, didReceiveMessage message: [String : Any]) {
        print("phone received app context: ", message)
        if let temperature = message["DataKey"] as? String {
            DispatchQueue.main.async {
                self.transferButton.setTitle(temperature, for: .normal)
                self.label.text=temperature
            }
        }

    }

}

Apple Watch: 

//  InterfaceController.swift

import WatchKit
import Foundation
import WatchConnectivity


class InterfaceController: WKInterfaceController {

    var watchSession: WCSession? {
        didSet {
            if let session = watchSession {
                session.delegate = self
                session.activate()
            }
        }
    }


    @IBOutlet weak var temperatureLabel: WKInterfaceButton!

    private func sendDict(_ dict: [String: Any]) {
        self.watchSession?.sendMessage(dict, replyHandler: nil, errorHandler: {error in print(error.localizedDescription)})
    }

    @IBAction func button() {
        let urg = ["DataKey":UUID().uuidString]
        sendDict(urg)
        print("watch sent app context \(urg)")
    }

}

extension InterfaceController: WCSessionDelegate {

    #if os(iOS)
    public func sessionDidBecomeInactive(_ session: WCSession) { }
    public func sessionDidDeactivate(_ session: WCSession) {
        session.activate()
    }
    #endif

    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        print("Session activation did complete")
    }

    func session(_ session: WCSession, didReceiveMessage message: [String : Any]) {
        print("watch received app context: ", message)
        if let temperature = message["DataKey"] as? Int {
            self.temperatureLabel.setTitle(String(temperature))
        }

    }

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

        watchSession = WCSession.default

    }

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

}
