I'm working on a watch app. I have to send data from the mobile to watch.
This is working properly.
The main problem occurs when I'm sending message from watch to mobile app because I want that the communication to be initiated by watch app. I have implemented the method to send data from watch to mobile app but always getting this
"WCErrorDomain Code=7014 "Payload could not be delivered." error.
I'm using xcode 7.3 and watchOS version is 2.0.
One more thing: is it possible that the sendMessage method opens the mobile app in background using watch connectivity framework?? Or if anyone knows any other way to open the mobile app in background then please suggest me. Thanks in advance.
session.sendMessage(message, replyHandler: { reply in
}, errorHandler: { error in
print("error: \(error)")
})
EDIT
In AppDelegate and ExtensionDelegate:
override init() {
super.init()
setupWatchConnectivity()
}
private func setupWatchConnectivity() {
if WCSession.isSupported() {
let session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
}
}
In ExtensionDelegate:
func sendMessage(){
let session = WCSession.defaultSession()
let applicationData:[String:AnyObject] = ["text":"test", "badgeValue": 100 ]
WatchSessionManager.sharedManager.sendMessage(applicationData, replyHandler: {replyMessage in
print("reply received from iphone")
}, errorHandler: {(error ) -> Void in
// catch any errors here
print("no reply message from phone")
})
}
In AppDelegate:
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {
let text = message["text"] as! String
let badgeValue = message["badgeValue"] as! Int
dispatch_async(dispatch_get_main_queue()) { () -> Void in
print("iphone received message from watch App")
self.sendNotification(text, badgeValue: badgeValue)
let applicationDict = ["wake": "nowAwake"]
replyHandler(applicationDict as [String : String])
}
}
In watchSessionManager :
func sendMessage(message: [String : AnyObject], replyHandler: (([String : AnyObject]) -> Void)?, errorHandler: ((NSError) -> Void)? = nil){
session.sendMessage(message, replyHandler: { reply in
}, errorHandler: { error in
print("error: \(error)")
})
print("mesage %#",message)
}

Working on a personal project and trying to receive content from an Apple Watch. The data being sent is fine but I get no response from either the phone or the watch.
Inside AppDelegate I have a session started inside didFinishLaunchingWithOptions and it conforms to WCSessionDelegate.
func session(_ session: WCSession, didReceiveMessage message: [String : Any], replyHandler: #escaping ([String : Any]) -> Void) {
var replyValues = [String : Any]()
switch message["command"] as! String {
case "logAttempt":
print("Log attempt")
replyValues["response"] = "true"
case "getData":
print("Get course data")
replyValues["response"] = "true"
default:
break
}
replyHandler(replyValues)
Inside the WatchKit class it also conforms to WCSessionDelegate and has the following to send message to the phone.
session.sendMessage(data, replyHandler: { replyHandler in
print(replyHandler)
if let response = replyHandler["response"] as? String {
print("app: Response from app to watch: \(response)")
} else {
print("error: Somethings wrong!: \(replyHandler["response"])")
}
}) { error in
print("Error: \(error.localizedDescription)")
}
ExtensionDelegate.swift file also conforms to WCSessionDelegate and starts a session inside applicationDidFinishLaunching. Struggling to get this working.
Thanks!
Edit: Setting up watch inside appDel:
fileprivate func setupWatch() {
if WCSession.isSupported() {
session = WCSession.default
session!.delegate = self
session!.activate()
}
}
How to quickly load data on Apple Watch? UserDefaults doesn't work since watchOS 2, so we can only use WCSessionDelegate, right?
Now, on Watch App start I call wcSession?.sendMessage(someThing, replyHandler: someFunc, errorHandler: otherFunc), then on iPhone app I send back some data in
func session(_ session: WCSession, didReceiveMessage message: [String : Any], replyHandler: #escaping ([String : Any]) -> Void)
And finally receive it on watch app in func session(_ session: WCSession, didReceiveMessage message: [String : Any]), but that takes like 3 seconds.
What would be better way to get data on start up?
You could try using the reply Handler function instead of initiating a new message. It should work faster.
Call this from watch:
func sendRequest() {
if session.activationState == .activated && session.isReachable {
session.sendMessage(["Watch Message" : "Request"], replyHandler: { (reply) in
// Handle reply here
}, errorHandler: { (error) in
print("***** Error Did Occur: \(error) *****")
})
}
}
Handle and Respond on Phone:
func session(_ session: WCSession, didReceiveMessage message: [String : Any], replyHandler: #escaping ([String : Any]) -> Void) {
if let messageFromWatch = message["Watch Message"] {
let messageData = messageFromWatch as! String
// Message From Watch to Activate Watch Connectivity Session
if messageData == "Request" {
replyHandler(["Response" : data])
}
}
}
I'm implementing simple one-line communication between iOS app and watchKit with sendMessage.
The issue is - the communication is continuous.
The user presses a button on appleWatch, same action happens on Phone e.t.c.
Unfortunately, after two or three actions - the iOS app stops responding.
As advised by some on the forums - i've implemented backgroundTaskWithExpirationHandler, however, it doesn't work (doesn't give me even a promised three minute timeout).
Here's my code in the iOS app AppDelegate
func session(session: WCSession, didReceiveMessage message: [String : AnyObject]) {
//recieve messages from watch
print(message["b"]! as? String)
let sweetN = message["b"]! as? String
//var sweetB = message["abs"]! as? [Int : Bool]
dispatch_async(dispatch_get_main_queue(), {
let taskID = self.beginBackgroundUpdateTask()
if sweetN == "peeks"{
if WCSession.isSupported(){
let message = [ "gettingData": "datareceived" ]
session.sendMessage(message, replyHandler: { replyDict in }, errorHandler: { error in })
}
}
self.endBackgroundUpdateTask(taskID)
})
}
func beginBackgroundUpdateTask() -> UIBackgroundTaskIdentifier {
return UIApplication.sharedApplication().beginBackgroundTaskWithExpirationHandler({})
}
func endBackgroundUpdateTask(taskID: UIBackgroundTaskIdentifier) {
UIApplication.sharedApplication().endBackgroundTask(taskID)
}
This worked for me.
You have to set the WCSession in the app delegate like:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if WCSession.isSupported() {
let session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
}
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {
replyHandler(["message": "received!"])
}
and in the apple watch: the file extension delegate.swift do the same:
override init() {
if WCSession.isSupported() {
let session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
}
}
So I am using Watch Connectivity to request an array from the iPhone to the Watch.
The idea was to sendMessage from the watch, and the iPhone will reply with the array within the didReceiveMessage method.
However the iPhone does not seem to be responding, I thought the iPhone would open the application when I send the message from the Watch. I have tried even opening the application when I sendMessage but still no luck. When I wait long enough I get the following error message:
Error Domain=WCErrorDomain Code=7012 "Message reply took too long."
UserInfo={NSLocalizedDescription=Message reply took too long.,
NSLocalizedFailureReason=Reply timeout occured.}
Does anybody know where I may be going wrong ?
Apple Watch
import WatchKit
import Foundation
import CoreData
import WatchConnectivity
class BookmarkedInterfaceController: WKInterfaceController, WCSessionDelegate {
var session : WCSession!
var objects: [AnyObject]!
#IBOutlet var table: WKInterfaceTable!
override func willActivate() {
super.willActivate()
//Check if session is supported and Activate
if (WCSession.isSupported()) {
session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
}
sendMessageToIphone()
}
func sendMessageToIphone() {
if WCSession.defaultSession().reachable {
print("WCSession is reachabe")
let messageDict = ["Request": "iPhone Can You Give Me The Array"]
WCSession.defaultSession().sendMessage(messageDict, replyHandler: { (replyDict) -> Void in
print(replyDict)
}, errorHandler: { (error) -> Void in
print(error)
})
}
}
func session(session: WCSession, didReceiveMessage message: [String : AnyObject]) {
//recieving message from iphone
print("recieved message from iphone \(message)")
objects.append(message["Array"]!)
print("Objects array = \(objects)")
}
The console outputs
WCSession is reachabe
Array nil
iPhone App Delegate
import UIKit
import CoreData
import WatchConnectivity
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, WCSessionDelegate {
var window: UIWindow?
var session : WCSession!
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
//Check if session is supported and Activate
if (WCSession.isSupported()) {
session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
}
}
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {
print("did recieve message from Watch")
let applicationData = ["Array":["One", "Two", "Three"]]
replyHandler(applicationData)
}
Nothing from the iPhone is being executed. Even when I manually open the app.
If you want the reply to the message the watch sent to contain the requested data, you should change your code to the following:
Watch
func sendMessageToIphone() {
if WCSession.defaultSession().reachable {
print("WCSession is reachabe")
let messageDict = ["Request": "iPhone Can You Give Me The Array"]
WCSession.defaultSession().sendMessage(messageDict, replyHandler: { (replyDict) -> Void in
print("Array \(replyDict["array"])")
}, errorHandler: { (error) -> Void in
print(error)
})
}
}
Phone
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {
print("did recieve message from Watch")
let applicationData = ["Array":["One", "Two", "Three"]]
//If identifier from recievedMessage is for Objects
replyHandler(applicationData)
}
And separately, the reason why the sendMessage from the phone is not received by the watch is because you've implemented the wrong delegate method for the sendMessage invocation you are using.
If you call sendMessage with a nil replyHandler then this delegate method will be invoked on the receiving side:
func session(session: WCSession, didReceiveMessage message: [String : AnyObject])
If you call sendMessage with a non-nil replyHandler then this delegate method will be invoked on the receiving side:
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void)
You must activate the session before sending the message .Also you must set the delegate before you activate the session because you may lose some pending messages.
iphone side :
import UIKit
import WatchConnectivity
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, WCSessionDelegate {
var window: UIWindow?
var session : WCSession!
func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {
print("did recieve message from Watch")
let applicationData = ["Array":["One", "Two", "Three"]]
//If identifier from recievedMessage is for Objects
session.sendMessage(applicationData, replyHandler: { reply in
print("Got reply: \(reply)")
}, errorHandler: { error in
print("error: \(error)")
})
}
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
return true
}
}
iWatch extension InterfaceController
You must activate the session in the interface controller willactivate method.
import WatchKit
import Foundation
import WatchConnectivity
class InterfaceController: WKInterfaceController, WCSessionDelegate {
var session : WCSession!
var objects: [AnyObject]!
override func awakeWithContext(context: AnyObject?) {
super.awakeWithContext(context)
// Configure interface objects here.
}
override func willActivate() {
// This method is called when watch view controller is about to be visible to user
super.willActivate()
session = WCSession.defaultSession()
session.delegate = self
session.activateSession()
objects = []
sendMessageToIphone()
}
override func didDeactivate() {
// This method is called when watch view controller is no longer visible
super.didDeactivate()
}
func sendMessageToIphone() {
if WCSession.defaultSession().reachable{
print("WCSession is reachabe")
let messageDict = ["Request": "iPhone Can You Give Me The Array"]
WCSession.defaultSession().sendMessage(messageDict, replyHandler: { (replyDict) -> Void in
print(replyDict)
}, errorHandler: { (error) -> Void in
print(error)
})
}
}
func session(session: WCSession, didReceiveMessage message: [String : AnyObject]) {
//recieving message from iphone
print("recieved message from iphone \(message)")
objects.append(message["Array"]!)
print("Objects array = \(objects)")
}
}
Note. Run the iphone application first. Then Run the extension and keep the iphone app in foreground.
I have a dictionary
dict = [Int : Bool]
and i was wondering if there is a simple way to send it to iPhone from watch and vice-versa through interactive messaging in WatchConnectivity framework?
Thank you.
You can do so like this:
if (WCSession.isSupported()) {
let session = WCSession.default
session.delegate = self
session.activate()
}
let dict = [Int : bool]
let message = ["message" : dict]
WCSession.default.sendMessage(message,
replyHandler: { (reply) -> Void in
},
errorHandler: { (error) -> Void in
}
)
In your watchkit extention write following code :
func getDataFromParentApp(image: String) {
let dictionary = ["Desired Word":image]
WKInterfaceController.openParentApplication(dictionary) {
(replyInfo, error) -> Void in
}
And in the AppDelegate write following one :
func application(application: UIApplication!,
handleWatchKitExtensionRequest userInfo: [NSObject : AnyObject]!,
reply: (([NSObject : AnyObject]!) -> Void)!) {
getImageForWordThatRhymesWithDat(userInfo, reply)
}
