passing data between sirikit intent handler and the app

ios does not let the containing app and the contained extensions to share a common container, so UserDefaults is the proposed solution.

I have tried using UserDefaults with sirikit intent handler assuming the handler behaves as an extension as follows :

inside IntentHandler.swift

let shared = UserDefaults(suiteName:XXXXXXXX.group...)
shared?.set("saved value 1", forKey: "key1")
shared?.set("saved value 2", forKey: "key2")
shared?.set("saved value 3", forKey: "key3")

inside ViewController.swift in viewDidLoad

let shared = UserDefaults(suiteName:XXXXXXXX.group...)
if let temp1 = shared?.string(forKey:"key1")
{
contentLabel.text = temp1
}
if let value = shared?.string(forKey: "key2")
{
valueLabel.text = value
} 
if let key = shared?.string(forKey: "key3")
{
keyLabel.text = key
}

i can see the strings corresponding to key1 and key2 on my ipad screen but not for key3, peppering the code with synchronizes does not help.

here are my questions :

1) are sirikit handlers different from other extensions? if yes how to pass data to my app? if not am i using UserDefaults incorrectly?

2) is there a better way to handle IPC between the app and its extensions where i just need to pass simple string messages between them.

using swift 3.0 and xcode 8.2.1

Check that you have the App Group enabled for all targets you want to access the group from. Check in project -> your target -> capabilities under "App Groups".

There's something called MMWomhole. It will definitely do the work.
