Hi.
There is something missing on the email you sent.
You said
I added in my DeviceRegistration.swift file the method:
But nothing appears, not sure if the mail client removed the code.
Do you see any error message on Xcode console? If yes, share them.
Do you have a paid Apple developer account? Push notifications don't work on free accounts.
Are you testing on a real device? Push notifications don't work on simulator.
Is the device asking for the push permissions?
Is your server available online so I can take a look?
