Background Tag Reading! Only from iPhone Xs line up.
Requirements
The NFC needs to have a universal link associated with it, so the phone can understand which apps to open.
By default Safari will process the NFC tags with universal links to apps not in the device.
Availability
Anytime the screen is on except:
Device has never been unlicked
Core NFC reader session is active
Apple Wallet in use
Video camera in use
Airplane mode
How to manage the tag delivery in your app.
Like any other NSUserActivity instance, via the appDelegate application(_:continue:restorationHandler:).
Access the ndefMessagePayload property of the NSUserActivity.
For universal link, we need to register the Associated Domains in the app capabilities.
