ericlewis / CodableAppStorage.swift

Last active July 3, 2025 22:13

Using Codable with AppStorage, the easy way!

	import Foundation
	import SwiftUI

	// MARK: Demo

	struct Example: RawRepresentable, Codable {
	let id: UUID
	}

	// This is functionally the same as above, but we have a neater type without creating a new protocol.

Last active February 17, 2022 16:31

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

ericlewis / Toggle+Label.swift

Created February 16, 2022 15:19

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 }

ericlewis / Components+Label.swift

Created February 16, 2022 14:49

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 {
