For a long while after shipping the iPhone SDK, there was a lot of duplication between the UIKit classes used by Apple (UITextViewLegacy, UITable for example) and the publicly facing ones (UITextView, UITableView) >>>

If you look closely at the UITextViewLegacy methods, you'd see some references to styles and web objects. internally all the way up to iOS 7, the system was using WebKit for rendering! you'd set your styles using ObjC, that would turn to CSS behind the scenes. >>>

Another favourite is the original https://Weather.app, with a cool origin story - starting out as an iPhone optimized version of the weather dashboard widget from OS X >>>

The shipped binary is just your regular Cocoa/ObjC MVC app. Some controllers, view and model objects. Nothing too interesting. BUT....

Scroll all the way at the bottom of WeatherController and we find webView:runJavaScriptAlertPanelWithMessage:
If you've done any WebKit work you know what this is: One of the WKUIDelegate's methods! 👌👌👌 (https://developer.apple.com/documentation/webkit/webuidelegate/1387807-webview)

And inside, a single NSLog();
Someone forgot to remove a debug print in the shipping binary! at some point this was a web app, running in a UIWebView... in fact Ken Kocienda and Richard Williamson mention this in their CHM interview https://www.youtube.com/watch?v=xImAMe32Itg
