All the speed of State with all the benefits of App/SceneStorage!
import SwiftUI
// MARK: Demo
struct ContentView: View {
@State
private var isActive = false
@SceneStorage("OtherKey")
private var isActiveStock = false

An initializer overload which also pushes an environment value on toggle status to the toggle's label.
import SwiftUI
struct IsToggledOnKey: EnvironmentKey {
static let defaultValue: Bool = false
}
extension EnvironmentValues {
fileprivate var _isToggledOn: Bool {
get { self[IsToggledOnKey.self] }
set { self[IsToggledOnKey.self] = newValue }

Initializer overloads to make working with labels easier.
import SwiftUI
extension Toggle where Label == SwiftUI.Label<Text, Image> {
public init(_ titleKey: LocalizedStringKey, systemImage named: String, isOn: Binding<Bool>) {
self.init(isOn: isOn, label: { Label(titleKey, systemImage: named) })
}
public init(_ titleKey: LocalizedStringKey, image named: String, isOn: Binding<Bool>) {
self.init(isOn: isOn, label: { Label(titleKey, image: named) })
}

Customize the separator insets on lists in SwiftUI. Only tested on iOS 15. Does not work on SidebarListStyles or interface idioms that aren't pad / phone.
struct ContentView: View {
var body: some View {
List {
ForEach(0..<100) { index in
Text("Index: \(index)")
.listRowSeparatorInsets(
.init(
top: 0,
left: CGFloat(index) * 5,

PagingView by working with SwiftUI internals. Useful for building "flat" view containers, like a paging view! The paging view itself uses yet another internal type. But serves as a good example for how to build a useful view.
import SwiftUI
struct ContentView: View {
@State
private var show = false
@State
private var selection = 0
var body: some View {

Using enums as Views. Just copy and paste into an App Playground.
import SwiftUI
struct Application: Identifiable {
enum Icon {
case url(URL)
case systemImage(String)
}
let id: UUID = .init()
let name: String

// Works.

ViewBuilder.buildBlock(VStack { ForEach(content.data) { _ in Text("Test") } })

}
// Crashes
