Mobile Tracking After The Removal Of The UDID

Some time ago Apple deprecated developer's access to the UDID for iOS devices and recently it has been reported that they are proactively rejecting apps that are submitted which still access it.  Many networks have relied solely upon this feature to track user activity between multiple apps on the same device but fortunately there are many good replacements that are all supported by Cake for mobile tracking in its absence. There are some things to consider when choosing the best replacement of the UDID for your network. I will briefly touch on a few of these replacement options as well as Cake’s opinions on them.
