In this project you're going to build on your new knowledge of
UIAlertController by producing a simple web browser app. Yes, I realize this is another easy project, but learning is as much about tackling new challenges as going over what you've already learned.
To sweeten the deal, I'm going to use this opportunity to teach you lots of new things:
WKWebView (Apple's extraordinary web widget),
UIToolbar (a toolbar component that holds
UIProgressView, delegation, key-value observing, and how to create your views in code. Plus, this is the last easy app project, so enjoy it while it lasts!
To get started, create a new Xcode project using the Single View App template, and call it Project4. Make sure Swift is selected for the language, then save the project on your desktop.
Open up Main.storyboard, select the view controller, and choose Editor > Embed In > Navigation Controller – that's our storyboard finished. Nice!
