If you work on a Swift project that follows the Model-View-ViewModel (MVVM) architecture or similar, you may want to jump to counterpart in Xcode from your view to your model, and then to your view model. (ie. by using Ctrl+Cmd+Up and Ctrl+Cmd+Down).

You can do this in recent versions of Xcode by setting a configuration default.

From a terminal, just type this command and press Enter:

defaults write com.apple.dt.Xcode IDEAdditionalCounterpartSuffixes -array-add "ViewModel" "View"

	// This playground shows you a few different ways to get device info via IOKit.
	// If you want to explore IOKit and look for interesting data I would download
	// the Additional Developer Tools from Apple and use the IORegistryExplorer app.
	// It makes it super easy to poke around in the IOKit planes.

	import IOKit

	// For convient access we can make a computed getter for the PlatformExpert.

	* I needed a property wrapper that fulfilled the following four requirements:
	*
	* 1. Values are stored in UserDefaults.
	* 2. Properties using the property wrapper can be used with SwiftUI.
	* 3. The property wrapper exposes a Publisher to be used with Combine.
	* 4. The publisher is only called when the value is updated and not
	* when_any_ value stored in UserDefaults is updated.
	*
	* First I tried using SwiftUI's builtin @AppStorage property wrapper

	// How to:
	// 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)
	// 7. Click “Download file” on the new side bar, then “Download CSV"
	// 8. Open the file and select the iOS/Android breakdown raw data
	// 9. Replace the sample data in this script with your data
