I am working on just apple watch app and I would like to send notification to user on specific time. But I can't find anywhere how can I achieve this.
Yes, it is possible. You just have to send a local notification from the Watch Extension's code.
Set up the
UNUserNotificationCenter in your
Watch App, then call
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil) anywhere in your Watch's code and you will receive the local notification on the Watch.
