iOS Every Uninstall/Install gives new Id

[ericbrunner]

@mofadevs try that:
var udid = UIDevice.CurrentDevice.IdentifierForVendor.AsString();

@jamesmontemagno Is there any way to get the real device Serial Number, IMEI, IMSI on iOS ? As far as I found out propably not but maybe you have an idea how to get a fixed ID from a device without having to launch the app get reads out the Vender Identifier. I want to use such fixed ID to authenticate a user. But the user has to tell me that ID prior to launch the app from System Settings -> About menu in the best case. Ok if that doesn't work I can of course read the Vender Id on first start of my app, transmit it to my backend and add the to my "registered" users database table but that would involve more unneccessary authentication code.

That is what the logic does. As far as I know it is not possible:
