Some fun points of interest

This is based on the default Master-Default App template when creating a new project

• Separated UISplitViewController work into a basic SplitViewController class to do delegate work
• Simplified TableView in MasterViewController and AppDelegate to simply this as an example

Attached are some gifs in "Captures" folder

• demonstration of app, shows how differently this pattern is handled on different device types
• may be similar between iPad and newer/bigger iPhones(?)

Some implementation notes

• remark that the delegate method in SplitViewController.swift handles showing/hiding
• programmatically, we designate a self.displayModeButtonItem for work
• just like UINavigationControllers, a UIViewController has a splitViewController property. You can directly interact with the splitViewController from a contained UIViewController, with properties inside like isCollapsed
