This is a plugin for iOS that allows you to get a UUID (Universal Unique Identifier) for a device.
Inspired from [StackOverflow: How to preserve identifierForVendor in ios after uninstalling ios app on device?] (http://stackoverflow.com/questions/21878560/how-to-preserve-identifierforvendor-in-ios-after-uninstalling-ios-app-on-device).
Uses SSKeychain Cocoa Pod.
tns plugin add nativescript-ios-uuid
var plugin = require("nativescript-ios-uuid");
var uuid = plugin.getUUID();
console.log("The device UUID is " + uuid);
