[Interest] QQmlEngine: Illegal attempt to connect to PlatformShim(0xb9b2fb58) that is in a different thread than the QML engine QQmlApplicationEngine(0xa17e1494.

[Kristoffersen, Even (NO14)]

The singleton one requires QML to be able to create the instance and own it doesn't it?

I'd switch to qmlRegisterUncreatableType()

Still having issues... But made some "progress"
So I changed to using qmlRegisterSingletonType<PlatformShim>("PlatformSupport", 1, 0 "PlatformShim", &getPlatformShim) However when I do I get 1 of 2 errors:
1. Element is not creatable:  when trying to declare a signal handler like PlatformShim { onPushNotificationReceived; {} } 2. Non-existent attached object: when trying to declare a signal handler (in QML) PlatformShim.onPushTokenReceived: { }

I also added:
QObject *getPlatformShim(QQmlEngine *engine, QJSEngine *scriptEngine) {
	Q_UNUSED(engine)
	Q_UNUSED(scriptEngine)

	return PlatformShim::instance();
}

and
import PlatformSupport 1.0 to the QML
