OK, so we went, with the family, to Orlando for Christmas vacation. And then Justin says: "Hey Dad, let's do an update on our Mobile App Case Study."
How could I say no to an invitation to write code with my youngest son? So, code we did; and we asked Angela to film it.
What motivated this were the letters we got from you guys, the viewers. (Thank you all). One of the things you asked is why we didn't do a more functional implementation.
We also wanted to clean up a few dangling issues and update the source code to the newer Swift style.
So, enjoy our Christmas vacation with us.
