Xcode deinit breakpoint for UIViewController

This breakpoint provides an easy way to track view controller deinitialization (deallocation) in UIKit-based applications. This can help finding memory leaks caused by retain cycles preventing view controllers from being deinitialized when dismissed or popped.

From Cédric Luthi's tweet in 2017:

Useful Xcode breakpoint. When you dismiss a controller and you don’t hear the pop sound (or see the log), you probably have a retain cycle.

//  1. Open the Firebase Analytics Dashboard
//  2. Scroll to bottom, where you see the "Users by Device model" widget
//  3. Click "View device models" in that widget (this opens the "Tech details" Firebase Analytics page)
//  4. Above the table shown in the new page, click on the “Device model” drop down menu and select “OS with Version”
//  5. Make sure to select “OS with version” and not “OS Version”
//  6. On the top right corner of the page, click on the “Share this report” icon (next to the date)
