I am trying to put a part of my Apple Watch app behind a paywall. For that, the iOS app automatically creates a dictionary with a true/false value, whether the content is purchases of not. The problem is, is no matter how I try, I cannot pass it to the Watch.
Here is my iOS ViewController:
import WatchConnectivity
class ViewController: UIViewController, WCSessionDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
//The dictionary to be passed to the Watch
var dictionaryToPass = ["product1": 0, "product2": 0]
//This will run, if the connection is successfully completed.
//BUG: After '.activate()'-ing the session, this function successfully runs in the '.activated' state.
func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
print("WCSession - activationDidCompleteWith:", activationState, "and error code:", error as Any)
switch activationState {
case .activated:
print("WCSession - activationDidCompleteWith .activated")
//session.transferUserInfo(dictionaryToPass)
case .inactive:
print("WCSession - activationDidCompleteWith .inactive")
case .notActivated:
print("WCSession - activationDidCompleteWith .notActivated")
default:
print("WCSession - activationDidCompleteWith: something other ")
break
}
}
func sessionDidBecomeInactive(_ session: WCSession) {
print("WCSession - sessionDidBecomeInactive")
}
func sessionDidDeactivate(_ session: WCSession) {
print("WCSession - sessionDidDeactivate")
}
//Pushing the button on the iOS storyboard will attempt iOS-watchOS connection.
@IBAction func tuiButton(_ sender: UIButton) {
let session = WCSession.default
if session.isReachable {
session.transferUserInfo(dictionaryToPass)
} else if WCSession.isSupported() {
session.delegate = self
session.activate()
}
}
@IBAction func sendmButton(_ sender: UIButton) {
let session = WCSession.default
if session.isReachable {
session.sendMessage(dictionaryToPass, replyHandler: { reply in
print(reply)
}, errorHandler: nil)
} else if WCSession.isSupported() {
session.delegate = self
session.activate()
}
}
}
And that's what I have on the watchOS's Interface Controller:
import WatchConnectivity
class InterfaceController: WKInterfaceController, WCSessionDelegate {
//The text label on the Watch Storyboard. Helps with debugging.
@IBOutlet weak var helloLabel: WKInterfaceLabel!
func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
print("watchOS - activationDidCompleteWith:", activationState)
}
//Whatever arrives, it will get printed to the console as well as the 'helloLabel' will be changed to help the debugging progress.
//BUG: This is the part, that never gets run, even tough the WCSession activated successfully.
func session(_ session: WCSession, didReceiveUserInfo userInfo: [String : Any] = [:]) {
print("watchOS - didReceiveUserInfo", userInfo)
helloLabel.setText("didReceiveUserInfo")
}
func session(_ session: WCSession, didReceiveMessage message: [String : Any]) {
print("watchOS - didReceiveMessage", message)
helloLabel.setText("didReceiveMessage")
}
func session(_ session: WCSession, didReceiveMessage message: [String : Any], replyHandler: @escaping ([String : Any]) -> Void) {
replyHandler(["does it work?": "yes sir"])
print("watchOS - didReceiveMessage", message)
helloLabel.setText("didReceiveMessage")
}
//Setting the Interface Controller as WCSession Delegate
private var session: WCSession = .default
override func awake(withContext context: Any?) {
session.delegate = self
session.activate()
}
//Activating the session on the watchOS side as well.
override func willActivate() {
if WCSession.isSupported() {
let session = WCSession.default
session.delegate = self
session.activate()
}
}
}
Turns out it was the watchOS simulator that was buggy. Quite a pity one from Apple.

If anyone else is in the same shoes, I recommend running the code on a physical device, it works perfectly there. The final working code can be found here if anyone from Google results is looking for that.
