How receive data background if app not Running?
Hell, I need recive data from iPhone to my app in Apple Watch background if apple Watch app not running.
in extension Delegate I use these func
session(_ session: WCSession, didReceiveMessage message: [String : Any])
and
session(_ session: WCSession, didReceiveMessageData messageData: Data, replyHandler: @escaping (Data) -> Void)
if app on Apple Watch data not received.
You're correct that the WatchConnectivity send & receive message functionality won't work for you if your watch app is in the background or not running. There are a number of ways to communicate with your app, and selecting the right one depends on what you're building.
