I'm new to the IOS (swift) world. If someone can give me an idea it would be wonderful. I'm trying to push notifications to all users within a radius. For example, if I'm in a park I want to send a notification to the people using my app in that specific park. If I move the notification is sent to devices on my new location.

I understand that "UNLocationNotificationTrigger" triggers notifications if a user enters in a determinate region, but that's not really what I want.

Thank you for your help

This should be done on the server side. You must track the location of all devices. And when necessary, you calculate the distance of each user to a particular device and send them a notification. You should not load one device with such logic.

  • Thank you for your answer. Yes, I was afraid of storing users' locations on my backend. I know it violates their privacy. – Gaby Jun 04 '20 at 21:08
  • Then,on backend you could store maybe some kind of curent area of user, and work with that area. You track location of user inside app, and you dynamically change his *curent area* – Alexey Kolchedanstev Jun 04 '20 at 21:16
