UIDevice uniqueIdentifier Deprecated – What To Do Now?
I’m new to iOS development and am confused about how to track users. I need to identify unique devices/users for certain personalization features on the server-side.
I heard UDID is not longer supported, so what is the sanctioned way to do this? or do I have to make new users register first?
This will be the same across all your apps from a given vendor on a given device.
