iPadOS Design Guidelines

Comprehensive rules for building iPad-native apps following Apple's Human Interface Guidelines. iPad is not a big iPhone -- it demands adaptive layouts, multitasking support, pointer interactions, keyboard shortcuts, and inter-app drag and drop. These rules extend iOS patterns for the larger, more capable canvas.

1. Responsive Layout (CRITICAL)

1.1 Use Adaptive Size Classes

iPad presents two horizontal size classes: regular (full screen, large splits) and compact (Slide Over, narrow splits). Design for both. Never hardcode dimensions.

struct AdaptiveView: View {
    @Environment(\.horizontalSizeClass) var sizeClass

    var body: some View {
        if sizeClass == .regular {
            TwoColumnLayout()
        } else {
            StackedLayout()
        }
    }
}

1.2 Don't Scale Up iPhone UI

iPad layouts must be purpose-built. Stretching an iPhone layout across a 13" display wastes space and feels wrong. Use multi-column layouts, master-detail patterns, and increased information density in regular width.

1.3 Support All iPad Screen Sizes

Design for the full range: iPad Mini (8.3"), iPad (11"), iPad Air (11"/13"), and iPad Pro (11"/13"). Use flexible layouts that redistribute content rather than simply scaling.

1.4 Column-Based Layouts for Regular Width

In regular width, organize content into columns. Two-column is the most common (sidebar + detail). Three-column works for deep hierarchies (sidebar + list + detail). Avoid single-column full-width layouts on large screens.

struct ThreeColumnLayout: View {
    var body: some View {
        NavigationSplitView {
            SidebarView()
        } content: {
            ContentListView()
        } detail: {
            DetailView()
        }
    }
}

1.5 Respect Safe Areas

iPad safe areas differ from iPhone. Older iPads have no home indicator. iPads in landscape have different insets than portrait. Always use safeAreaInset and never hardcode padding for notches or indicators.

1.6 Support Both Orientations

iPad apps must work well in both portrait and landscape. Landscape is the dominant orientation for productivity. Portrait is common for reading. Adapt column counts and layout density to orientation.

2. Multitasking (CRITICAL)

2.1 Support Split View

Your app must function correctly at 1/3, 1/2, and 2/3 screen widths in Split View. At 1/3 width, your app receives compact horizontal size class. Content must remain usable at every split ratio.

2.2 Support Slide Over

Slide Over presents your app as a compact-width overlay on the right edge. It behaves like an iPhone-width app. Ensure all functionality remains accessible in this narrow mode.

2.3 Handle Stage Manager

Stage Manager allows freely resizable windows and multiple windows simultaneously. Your app must:

• Resize fluidly to arbitrary dimensions

• Support multiple scenes (windows) showing different content

• Not assume any fixed size or aspect ratio

  @main struct MyApp: App { var body: some Scene { WindowGroup { ContentView() } // Support multiple windows WindowGroup("Detail", for: Item.ID.self) { $itemId in DetailView(itemId: itemId) } } }

2.4 Never Assume Full Screen

The app may launch directly into Split View or Stage Manager. Do not depend on full-screen dimensions during setup, onboarding, or any flow. Test your app at every possible size.

2.5 Handle Size Transitions Gracefully

When the user resizes via multitasking, animate layout changes smoothly. Preserve scroll position, selection state, and user context across size transitions. Never reload content on resize.

2.6 Support Multiple Scenes

Use UIScene / SwiftUI WindowGroup to let users open multiple instances of your app showing different content. Each scene is independent. Support NSUserActivity for state restoration.

3. Navigation (CRITICAL)

3.1 Sidebar for Primary Navigation

In regular width, replace the iPhone tab bar with a sidebar. The sidebar provides more room for navigation items, supports sections, and feels native on iPad.

struct AppNavigation: View {
    @State private var selection: NavigationItem? = .inbox

    var body: some View {
        NavigationSplitView {
            List(selection: $selection) {
                Section("Main") {
                    Label("Inbox", systemImage: "tray")
                        .tag(NavigationItem.inbox)
                    Label("Drafts", systemImage: "doc")
                        .tag(NavigationItem.drafts)
                    Label("Sent", systemImage: "paperplane")
                        .tag(NavigationItem.sent)
                }
                Section("Labels") {
                    // Dynamic sections
                }
            }
            .navigationTitle("Mail")
        } detail: {
            DetailView(for: selection)
        }
    }
}

3.2 Automatic Tab-to-Sidebar Conversion

SwiftUI TabView with .sidebarAdaptable style automatically converts to a sidebar in regular width. Use this for seamless iPhone-to-iPad adaptation.

TabView {
    Tab("Home", systemImage: "house") { HomeView() }
    Tab("Search", systemImage: "magnifyingglass") { SearchView() }
    Tab("Profile", systemImage: "person") { ProfileView() }
}
.tabViewStyle(.sidebarAdaptable)

3.3 Three-Column Layout for Complex Hierarchies

Use NavigationSplitView with three columns when your information architecture has three levels: category > list > detail. Examples: mail (accounts > messages > message), file managers, settings.

3.4 Toolbar at Top

On iPad, toolbars live at the top of the screen in the navigation bar area, not at the bottom like iPhone. Place contextual actions in .toolbar with appropriate placement.

.toolbar {
    ToolbarItemGroup(placement: .primaryAction) {
        Button("Compose", systemImage: "square.and.pencil") { }
    }
    ToolbarItemGroup(placement: .secondaryAction) {
        Button("Archive", systemImage: "archivebox") { }
        Button("Delete", systemImage: "trash") { }
    }
}

3.5 Detail View Should Never Be Empty

When no item is selected in a list/sidebar, show a meaningful empty state in the detail area. Use a placeholder with icon and instruction text, not a blank screen.

3.6 Reduce Recall in Large-Canvas Navigation

Keep sidebar selection, search terms, and disclosure state visible and preserved across size changes and scene switches. In multi-column layouts, users should resume from structure on screen, not from memory.

4. Pointer & Trackpad (HIGH)

4.1 Add Hover Effects to Interactive Elements

All tappable elements should respond to pointer hover. The system provides automatic hover effects for standard controls. For custom views, use .hoverEffect().

Button("Action") { }
    .hoverEffect(.highlight)  // Subtle highlight on hover

// Custom hover effect
MyCustomView()
    .hoverEffect(.lift)  // Lifts and adds shadow

4.2 Pointer Magnetism on Buttons

The pointer should snap to (be attracted toward) button bounds. Standard UIKit/SwiftUI buttons get this automatically. For custom hit targets, ensure the pointer region matches the tappable area using .contentShape().

4.3 Support Right-Click Context Menus

Right-click (secondary click) should present context menus. Use .contextMenu which automatically supports both long-press (touch) and right-click (pointer).

Text(item.title)
    .contextMenu {
        Button("Copy", systemImage: "doc.on.doc") { }
        Button("Share", systemImage: "square.and.arrow.up") { }
        Divider()
        Button("Delete", systemImage: "trash", role: .destructive) { }
    }

4.4 Trackpad Scroll Behaviors

Support two-finger scrolling with momentum. Pinch to zoom where appropriate. Respect scroll direction preferences. For custom scroll views, ensure trackpad gestures feel natural alongside touch gestures.

4.5 Customize Cursor for Content Areas

Change cursor appearance based on context. Text areas show I-beam. Links show pointer hand. Resize handles show resize cursors. Draggable items show grab cursor.

4.6 Pointer-Driven Drag and Drop

Pointer users expect click-and-drag for rearranging, selecting, and moving content. Combine with multi-select via Shift-click and Cmd-click.

5. Keyboard (HIGH)

5.1 Cmd+Key Shortcuts for All Major Actions

Every primary action must have a keyboard shortcut. Standard shortcuts are mandatory:

Button("New Document") { createDocument() }
    .keyboardShortcut("n", modifiers: .command)

5.2 Discoverability via Cmd-Hold Overlay

When the user holds the Cmd key, iPadOS shows a shortcut overlay. Register all shortcuts using .keyboardShortcut() so they appear in this overlay. Group related shortcuts logically.

5.3 Tab Key Navigation Between Fields

Support Tab to move forward and Shift+Tab to move backward between form fields and focusable elements. Use .focusable() and @FocusState to manage keyboard focus order.

struct FormView: View {
    @FocusState private var focusedField: Field?

    var body: some View {
        Form {
            TextField("Name", text: $name)
                .focused($focusedField, equals: .name)
            TextField("Email", text: $email)
                .focused($focusedField, equals: .email)
            TextField("Phone", text: $phone)
                .focused($focusedField, equals: .phone)
        }
    }
}

5.4 Never Override System Shortcuts

Do not claim shortcuts reserved by the system: Cmd+H (Home), Cmd+Tab (App Switcher), Cmd+Space (Spotlight), Globe key combinations. These will not work and create confusion.

5.5 Detect Hardware Keyboard

Adapt UI when a hardware keyboard is connected. Hide the on-screen keyboard shortcut bar. Show keyboard-optimized controls. Use GCKeyboard or track keyboard visibility to detect state.

5.6 Arrow Key Navigation

Support arrow keys for navigating lists, grids, and collections. Combine with Shift for multi-selection. This is essential for productivity-focused apps.

5.7 Shortcuts Must Be Discoverable

Do not rely on users memorizing shortcut vocabularies. Expose commands through the Cmd-hold overlay, menu labels, and visible focus movement so people learn shortcuts by recognition and repetition.

6. Apple Pencil (MEDIUM)

6.1 Support Scribble

iPadOS converts handwriting to text in any standard text field automatically. Do not disable Scribble. For custom text input, adopt UIScribbleInteraction. Test that Scribble works in all text entry points.

6.2 Double-Tap Tool Switching

Apple Pencil 2 and later supports double-tap to switch tools (e.g., pen to eraser). If your app has drawing tools, implement the UIPencilInteraction delegate to handle double-tap.

6.3 Pressure and Tilt for Drawing

For drawing apps, respond to force (pressure) and altitudeAngle/azimuthAngle (tilt) from pencil touch events. Use these for variable line width, opacity, or shading.

6.4 Hover Detection (M2+ Pencil)

Apple Pencil with hover (M2 iPad Pro and later) provides position data before the pencil touches the screen. Use this for preview effects, tool size indicators, and enhanced precision.

// UIKit hover support via UIHoverGestureRecognizer
let hoverRecognizer = UIHoverGestureRecognizer(target: self, action: #selector(pencilHoverChanged(_:)))
hoverRecognizer.allowedTouchTypes = [NSNumber(value: UITouch.TouchType.pencil.rawValue)]
canvas.addGestureRecognizer(hoverRecognizer)

@objc func pencilHoverChanged(_ hover: UIHoverGestureRecognizer) {
    let location = hover.location(in: canvas)
    showBrushPreview(at: location)
}

6.5 PencilKit Integration

For note-taking and annotation, use PKCanvasView from PencilKit. It provides a full drawing experience with tool picker, undo, and ink recognition out of the box.

import PencilKit

struct DrawingView: UIViewRepresentable {
    @Binding var canvasView: PKCanvasView

    func makeUIView(context: Context) -> PKCanvasView {
        canvasView.tool = PKInkingTool(.pen, color: .black, width: 5)
        canvasView.drawingPolicy = .anyInput
        return canvasView
    }
}

7. Drag and Drop (HIGH)

7.1 Inter-App Drag and Drop is Expected

iPad users expect to drag content between apps. Support dragging content out (as a source) and dropping content in (as a destination). This is a core iPad interaction.

// As drag source
Text(item.title)
    .draggable(item.title)

// As drop destination
DropTarget()
    .dropDestination(for: String.self) { items, location in
        handleDrop(items)
        return true
    }

7.2 Multi-Item Drag

Users can pick up one item, then tap additional items to add them to the drag. Support multi-item drag by providing multiple NSItemProvider items. Show a badge count on the drag preview.

7.3 Spring-Loaded Interactions

When dragging over a navigation element (folder, tab, sidebar item), pause briefly to "spring open" that destination. Implement spring-loading on navigation containers to enable deep drop targets.

7.4 Visual Feedback for Drag and Drop

Provide clear visual states:

• Lift : Item lifts with shadow when drag begins
• Move : Destination highlights when drag hovers over valid target
• Drop : Animate insertion at drop point
• Cancel : Item animates back to origin

7.5 Support Universal Control

Universal Control lets users drag between iPad and Mac. If your app supports drag and drop with standard NSItemProvider and UTTypes, Universal Control works automatically.

7.6 Drop Delegates for Custom Behavior

Use DropDelegate for fine-grained control over drop behavior: validating drop content, reordering within lists, and handling drop position.

struct ReorderDropDelegate: DropDelegate {
    let item: Item
    @Binding var items: [Item]
    @Binding var draggedItem: Item?

    func performDrop(info: DropInfo) -> Bool {
        draggedItem = nil
        return true
    }

    func dropEntered(info: DropInfo) {
        guard let draggedItem,
              let fromIndex = items.firstIndex(of: draggedItem),
              let toIndex = items.firstIndex(of: item) else { return }
        withAnimation {
            items.move(fromOffsets: IndexSet(integer: fromIndex),
                      toOffset: toIndex > fromIndex ? toIndex + 1 : toIndex)
        }
    }
}

8. External Display (MEDIUM)

8.1 Provide Extended Content, Not Just Mirroring

When connected to an external display, show complementary content rather than duplicating the iPad screen. Presentations, reference material, or expanded views belong on the external display while controls stay on iPad.

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        // Additional scene for external display
        WindowGroup(id: "presentation") {
            PresentationView()
        }
    }
}

8.2 Handle Display Connection and Disconnection

Observe external display lifecycle via UIWindowScene events in your SceneDelegate or by listening for UIScene session notifications (UIApplication.didConnectSceneSessionNotification / UIApplication.didDisconnectSceneSessionNotification). Transition gracefully — if the external display disconnects mid-presentation, bring content back to the iPad screen without data loss.

// SceneDelegate: detect when a scene (external display window) connects or disconnects
func scene(_ scene: UIScene,
           willConnectTo session: UISceneSession,
           options connectionOptions: UIScene.ConnectionOptions) {
    guard let windowScene = scene as? UIWindowScene else { return }
    configureExternalDisplay(for: windowScene)
}

func sceneDidDisconnect(_ scene: UIScene) {
    restoreContentToiPad()
}

8.3 Support Full External Display Resolution

Use the full resolution and aspect ratio of the external display. Do not letterbox or pillarbox your content. In iOS 16+ multi-scene contexts, UIScreen.main is deprecated — query the connected display via UIWindowScene.coordinateSpace.bounds and UIWindowScene.screen.scale, or use @Environment(\.displayScale) in SwiftUI.

9. Accessibility (CRITICAL)

Impact: CRITICAL

Rule 9.1: VoiceOver Labels on All Interactive Elements

Every button, control, and interactive element must have a meaningful accessibility label. Icon-only toolbar items and custom views must use .accessibilityLabel().

Correct:

Button(action: compose) {
    Image(systemName: "square.and.pencil")
}
.accessibilityLabel("Compose new message")

Incorrect:

Button(action: compose) {
    Image(systemName: "square.and.pencil")
}
// VoiceOver reads "square.and.pencil" — meaningless to users

Rule 9.2: Support Dynamic Type Including Accessibility Sizes

Use semantic text styles (title, body, caption) so text scales with the user's preferred size. In iPad's larger canvas, never clamp text size or disable scaling. Test up to the five accessibility size steps.

Text("Section Header")
    .font(.headline)  // Scales with Dynamic Type automatically

Rule 9.3: Pointer Accessibility — Hover Must Not Be the Only Cue

Hover states (.hoverEffect) enhance pointer input but must not be the sole indicator of interactivity. Ensure all interactive elements are also distinguishable via color, shape, or label for VoiceOver and keyboard-only users.

Rule 9.4: Full Keyboard Access and Focus Routing

With Full Keyboard Access enabled, Tab must move focus through all interactive elements in logical order. In Split View and multi-window layouts, focus must not escape to a hidden or occluded window. Use @FocusState and .focusable() to control the keyboard focus graph.

struct FormView: View {
    @FocusState private var focusedField: Field?

    var body: some View {
        VStack {
            TextField("Name", text: $name)
                .focused($focusedField, equals: .name)
            TextField("Email", text: $email)
                .focused($focusedField, equals: .email)
        }
    }
}

Rule 9.5: VoiceOver in Split View — Separate Focus Contexts

In Split View, each app has its own VoiceOver focus context. Your app must not assume it occupies the full screen. Ensure VoiceOver can navigate your entire visible interface even at 1/3 or 1/2 split width. Do not hide actionable content outside the visible region without also removing it from the accessibility tree.

Rule 9.6: Respond to Bold Text

When the user enables Bold Text in Settings, custom-rendered text must adapt. SwiftUI text styles handle this automatically. UIKit code must check UIAccessibility.isBoldTextEnabled or use @Environment(\.legibilityWeight) in SwiftUI.

Correct:

// SwiftUI — handled automatically for standard text styles
Text("Section Header")
    .font(.headline)

// SwiftUI — custom rendering respects legibilityWeight
@Environment(\.legibilityWeight) var legibilityWeight

var body: some View {
    Text("Custom Label")
        .fontWeight(legibilityWeight == .bold ? .bold : .regular)
}

Incorrect:

// Hardcoded weight ignores Bold Text preference
label.font = UIFont.systemFont(ofSize: 17, weight: .regular)
// Missing: re-query font when UIAccessibility.boldTextStatusDidChangeNotification fires

Rule 9.7: Respond to Increase Contrast

When the user enables Increase Contrast in Settings, custom colors must provide higher-contrast variants. Use @Environment(\.colorSchemeContrast) in SwiftUI or UIAccessibility.isDarkerSystemColorsEnabled in UIKit.

Correct:

// SwiftUI
@Environment(\.colorSchemeContrast) var contrast

var separatorColor: Color {
    contrast == .increased ? Color.primary : Color.secondary
}

// UIKit
let useHighContrast = UIAccessibility.isDarkerSystemColorsEnabled
let borderColor: UIColor = useHighContrast ? .label : .separator

Incorrect:

// Static color ignores Increase Contrast setting
let borderColor = UIColor.separator // Always low-contrast; ignores user preference

Anti-Patterns

DO NOT: Scale Up iPhone Layouts

Stretching a single-column iPhone UI to fill an iPad screen wastes space, looks lazy, and provides a poor experience. Always redesign for the larger canvas.

DO NOT: Disable Multitasking

Never opt out of multitasking support. Users expect every app to work in Split View and Slide Over. Requiring full screen is hostile to iPad workflows.

DO NOT: Ignore the Keyboard

Many iPad users have Magic Keyboard or Smart Keyboard. An app with no keyboard shortcuts forces them to reach for the screen constantly. Provide shortcuts for all frequent actions.

DO NOT: Use iPhone-Style Bottom Tab Bars in Regular Width

Tab bars at the bottom waste vertical space on iPad and look out of place. Convert to sidebar navigation in regular width. SwiftUI does this automatically with .sidebarAdaptable.

DO NOT: Show Popovers as Full-Screen Sheets

On iPad, popovers should anchor to their source element as floating panels. Only use full-screen sheets for immersive content or flows that genuinely need the full screen. Avoid the iPhone pattern of everything being a sheet.

DO NOT: Ignore Pointer Hover States

Missing hover effects make the app feel broken when using a trackpad. Users cannot tell what is interactive. Always add hover feedback to custom interactive elements.

DO NOT: Hardcode Dimensions

Never hardcode widths, heights, or positions based on a specific iPad model. Use Auto Layout constraints, SwiftUI flexible frames, and GeometryReader for dynamic sizing.

DO NOT: Forget Drag and Drop

On iPad, drag and drop between apps is a core workflow. Not supporting it makes your app a dead end for content. At minimum, support dragging text, images, and URLs in and out.

DO NOT: Override System Keyboard Shortcuts

Claiming Cmd+H, Cmd+Tab, Cmd+Space, or Globe shortcuts will not work and confuses users who expect system behavior. Check Apple's reserved shortcuts list before assigning.

DO NOT: Present Dense Content Without Scrolling

Large iPad screens tempt designers to show everything at once. Content should still scroll when it exceeds the visible area. Never truncate content to avoid scrolling.
