A dump of the SwiftUI.framework binary for the iOS simulator (as of Xcode 12.0 beta 2) using the swift-reflection-dump tool.

Note: I used a Swift 5.3 compiler build from a few weeks ago that I had laying around. Because of ABI stability, I don't think the swift-reflection-dump version has to match the compiler version that was used to build the binary, but I'm not 100% sure.

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"

	import SwiftUI

	enum PreviewProviderMode: CaseIterable {

	/// Use for a light appearance preview.
	case lightMode

	/// Use for a dark appearance preview.
	case darkMode

	// Facebook:
	//
	// 1. Follow this guide (WITHOUT setting up a URL scheme in Xcode):
	// https://github.com/fullstackreact/react-native-oauth/issues/76#issuecomment-335902057
	//
	// 2. call startFacebookAuthenticationSession(appID:completionHandler:) on a window:
	//

	import SwiftUI

	extension Calendar {
	func generateDates(
	inside interval: DateInterval,
	matching components: DateComponents
	) -> [Date] {
	var dates: [Date] = []
	dates.append(interval.start)

	import Foundation

	// Diff values for better test assertions.
	//
	// Enums and collections left as an exercise for the reader.

	// A difference between two values
	struct Difference: CustomStringConvertible {
	let path: String
	let actual: String

	import Foundation

	// Diff objects for better test assertions.
	//
	// Implemented in a way that:
	// 1. The compiler generates as much code as possible
	// 2. You'll get a compiler error if you forget a property
	//
	// Nested support and collections left as an exercise for the reader.
