Apple OSX "Create NAT64 Network" to help test IPv6 is just not working for my laptop or computer or iPhone or iPad devices - SOLVED

	Overview:
	=========

	So you want to test your application, whether it be desktop, mobile or tablet for IPv6 compatibility.
	Apple make this easy as OSX has a nice hidden feature to enable your Apple laptop to create an IPv6 ONLY personal hotspot by sharing your existing (IPv4) internet connection. The problem is, you follow the instructions, but it is JUST NOT WORKING for you!
	Well, if you are like me and you spent way longer than you would have wanted, trying to get this working, this snippet of info may save you some time.

Encrypted Realm with secret in keychain in app supporting background fetch intermittently causes realm to fail to initialize and crash app at try! - SOLVED

	This is like a drop-in replacement for realms example swift project enabling encryption using the function getKey().

	https://github.com/realm/realm-cocoa/blob/master/examples/ios/swift/Encryption/ViewController.swift

	The following swift function is a drop in replacement, it documents the painful experience of an issue
	which has been unsolved for years till crashlytics revealed a very useful hint, which lead to the root cause
	and fix.

	Comments included for education on what the symptoms were, the cause and fix and other notes.

Enabling DNSSEC for domains registered on GoDaddy and Managed on AWS Route53 with Load Balancer - SOLVED and finally working

	First what is DNSSEC and other info of interest:

	A nice overview and explanation:
	https://www.upguard.com/blog/dnssec

	Which led me to want to know more about Root Authority, and also Root Cert Authorities:
	https://www.makeuseof.com/tag/your-data-given-to-nsa/ - scary
	https://www.tomshardware.com/news/google-bans-cnnic-root-ca,28873.html - nothing surprising
	https://www.iana.org/domains/root/servers - looks like mostly US entities, who ultimately will do what the government says. Looks like one country controls the internet.
