User Profile

Hi all, Is there a method which would allow a developer to uniquely identify a single contact across all synced iCloud devices? Specifically, if I had two phones signed into the same iCloud account with my app installed on both, can I reliably fetch and update the same synced contact on both devices? The documentation - https://developer.apple.com/documentation/contacts/cncontact/1403103-identifier states that a CNContact Identifier is unique to a device, which I confirmed.

Hey all,I'm working on a project which includes a large collection of objects to be displayed to the user in a table view. I decided to store data on my objects in a JSON file, but am struggling when it comes to various subclassed objects.For example, all objects are sublclassed from Car, and can be any number of different models (each with different properties). Is it reasonable to think that trying to decode one large JSON file with many Car subclasses in it is even worth the struggle of setting up a proper decoder?To those curious, here's a simplified structure of my JSON file, where "allModels" is an array containing objects with unique types (the name property correlates to the subclass name in my code), and an array of objects which are all the type declared in their respective objects. I essentially have a heterogeneous array of homogeneous objects.{ "name": "All Cars", "allModels": [ { "name": "Chevy", "IndividualCars": [ { "color": "blue", "wheels": 4 }, { "color": "red", "wheels": 4 } ] }, { "name": "Honda", "IndividualCars": [ { "color": "blue", "wheels": 4, "hasHondaThing": true }, { "color": "red", "wheels": 4, "hasHondaThing": false } ] } ] }Any insight would be much appreciated!-Reece
