UserInfo of UILocalNotification always nil

I am creating simple UILocalNotification, without scheduling, just from background with the following code:

let n = UILocalNotification()
n.alertBody = "\(nam) \(wat)"
n.userInfo = ["id": id, "t":type.rawValue]
n.soundName = UILocalNotificationDefaultSoundName
n.category = "call_chat"
app.scheduleLocalNotification(n)

I am printing userInfo inside

func application(_ application: UIApplication, didReceive notification: UILocalNotification)

Until here everything is fine. But I need to dismiss some of notifications with the same id later on and create new ones. When I am trying to get them with UIApplication.shared.scheduledLocalNotifications all of them has userInfo==nil in iOS9 and userInfo==["":""] in iOS10 beta.

Solution

  • So, finally I find out, that scheduledLocalNotifications doesn't contain notifications, that already shown. The only way is to store them in array, or use NSKeyArchiver like said here.
