Thanks for clearing this up.

At 3:00 it is said that “ Local Notifications are the ones that are used by applications that are on the device". So there are 3 posssiblities for Local Notifications: A local = inside local Wifi or Bluetooth network B local to the device (as hinted by WWDC talk) C local to the sending app I can send notifications from an app to itself. But the receiving apps UNNotificationContentExtension gets never called. I only see UNUserNotificationCenterDelegate methods being invoked. I cannot do: • notification from one app to another on the same device • notification from one app to another on a different device The sending app does see its own notifications via getPendingNotificationRequestsWithCompletionHandler. It sets the categoryIdentifier of the sent UNNotificationContent to “my test category”. The receiving app (same iOS device) never sees anything. Although it does setNotificationCategories with a UNNotificationCategory with the same category: “my test category”. This might indicate possibility “C”: local notifications are local to the sending app. Or it may just be a proof that I am doing it wrong. > > Communicate between watchOS, and iPhone: To be investigated later. > > Scott > >> On Dec 4, 2016, at 5:47 AM, Gerriet M.
