CarPlay App Categories

⚠️ Important: CarPlay apps require entitlements from Apple. You must request and receive approval for your specific app category before your app can connect to CarPlay.

CarPlay supports apps in the following 10 categories (each requires a separate entitlement):

• Audio & Podcasts (iOS 12+, depth limit: 5)

  • Entitlement: com.apple.developer.carplay-audio
  • Requirements: Audio playback, Now Playing integration, MPNowPlayingInfoCenter

• Communication (iOS 12+, depth limit: 5)

  • Entitlement: com.apple.developer.carplay-communication
  • Requirements: CallKit integration, SiriKit integration

• Navigation (iOS 12+, depth limit: 5)

  • Entitlement: com.apple.developer.carplay-maps
  • Requirements: Real-time navigation, route guidance, map rendering

• Parking (iOS 14+, depth limit: 5)

  • Entitlement: com.apple.developer.carplay-parking
  • Requirements: Location services, parking availability

• EV Charging (iOS 14+, depth limit: 5)

  • Entitlement: com.apple.developer.carplay-charging
  • Requirements: Charging station data, availability status

• Quick Food Ordering (iOS 14+, depth limit: 3)

  • Entitlement: com.apple.developer.carplay-quick-ordering
  • Requirements: Streamlined menu browsing, order placement, pickup

• Fueling (iOS 16+, depth limit: 3)

  • Entitlement: com.apple.developer.carplay-fueling
  • Requirements: Station locations, pump control, payment

• Driving Task (iOS 16+, depth limit: 3)

  • Entitlement: com.apple.developer.carplay-driving-task
  • Requirements: Tasks done while driving (road conditions, tolls, accessories). Must not duplicate navigation.

• Public Safety (iOS 14+, depth limit: 3)

  • Entitlement: com.apple.developer.carplay-public-safety
  • Requirements: Real-time safety information (hazards, speed cameras, emergency alerts)

• Voice-Based Conversational (iOS 26.4+, depth limit: 3)

  • Entitlement: com.apple.developer.carplay-voice-based-conversation
  • Requirements: Primarily voice-driven interaction. Uses CPVoiceControlTemplate as primary UI.

How to request entitlements:

1. Visit https://developer.apple.com/contact/carplay/
2. Describe your app's functionality and category
3. Wait for Apple's review and approval (typically 1-2 weeks)
4. Add the approved entitlement to your Xcode project

Template-Based UI

CarPlay uses a template-based system where Apple provides the UI components and you provide the content. This ensures:

• Driver-safe interfaces optimized for in-car use
• Consistent user experience across all CarPlay apps
• Automatic adaptation to different vehicle displays

Template Availability Matrix

Not all templates are available to every category. Key restrictions:

• Navigation only: CPMapTemplate
• Communication only: CPContactTemplate
• Audio apps: Max 4 tabs in CPTabBarTemplate; all others: max 5 tabs
• Food ordering / Fueling / Driving task / Public safety / Voice-based: Template depth limit of 3 (vs. 5 for audio, communication, navigation, parking, EV charging)

See references/developer_guide.md for full per-category template lists.

CarPlay Ultra

CarPlay Ultra is Apple's next-generation in-vehicle experience that deeply integrates with the vehicle's displays, including the instrument cluster, center console, and passenger displays. Apps that support CarPlay automatically work with CarPlay Ultra — no additional API adoption is required. CarPlay Ultra uses the same template-based system and entitlements.

Widgets in CarPlay (iOS 26+)

WidgetKit widgets can appear on the CarPlay home screen. To support CarPlay:

• Add .accessoryCircular or .accessoryRectangular to your widget's supportedFamilies
• Keep widget content simple and glanceable — no interactive controls
• Widgets refresh on the same timeline as the iPhone

Live Activities in CarPlay (iOS 26+)

Live Activities can appear in CarPlay for real-time updates (delivery tracking, sports scores, ride status). To opt in:

• Add .carPlay to your ActivityConfiguration's supplementalActivityFamilies
• Use compact and minimal presentations suitable for driving
• Live Activities appear as persistent banners in the CarPlay interface

Voice-Based Conversational Apps (iOS 26.4+)

A new app category for AI assistants and voice-driven experiences. Uses CPVoiceControlTemplate as the primary interface with:

• Action buttons for quick commands below the voice visualization
• Navigation bar buttons for supplemental controls
• Minimal visual UI — interaction is primarily through speech

Notifications in CarPlay

Apps can deliver notifications to CarPlay. Requirements:

• Request .carPlay in UNAuthorizationOptions when requesting notification permission
• Set .allowInCarPlay on UNNotificationCategory for categories that should appear on the CarPlay display
• Keep notification content brief and relevant to driving context

Assets Size Guide

Asset	Recommended Size

Alert image	44×44 pt
POI pin image	44×44 pt
Navigation maneuver symbol	44×44 pt
Now Playing artwork	44×44 pt (thumbnail), up to 256×256 pt (full)

Audio Handling

• Use AVAudioSession category .playback for audio apps
• Navigation voice prompts should use mode .voicePrompt with options .duckOthers and .interruptSpokenAudioAndMixWithOthers
• Audio apps must respond to MPRemoteCommandCenter events (play, pause, skip)
• Activate audio session before playback; deactivate when done

Accessing Data While iPhone is Locked

When the iPhone is locked, file access may be restricted. Use FileProtectionType.completeUntilFirstUserAuthentication or .none for files your CarPlay app needs. The default .completeUnlessOpen may prevent access.

Launching Other Apps

CarPlay apps can open other apps using CPTemplateApplicationScene.open(_:options:completionHandler:). This is useful for handing off to a phone-based flow (e.g., completing a purchase). The system will prompt the user before switching.

Usage Guidelines

1. Use appropriate templates for your app category
2. Keep content simple - limit items and text for driver safety
3. Provide large, clear images for better visibility
4. Handle connection/disconnection gracefully
5. Test in CarPlay Simulator before testing in vehicle
6. Follow distraction guidelines - no video, animations, or ads while driving

Testing with CarPlay Simulator

There are two ways to test CarPlay:

Option 1: Xcode Simulator Window

1. Open your CarPlay app project in Xcode
2. Select an iOS Simulator as your run destination
3. In the Simulator menu: I/O > External Displays > CarPlay
4. A CarPlay display window will appear alongside the iOS simulator

Option 2: Standalone CarPlay Simulator (Mac App)

1. Download Additional Tools for Xcode from developer.apple.com
2. Install the CarPlay Simulator app
3. Connect a physical iPhone to your Mac
4. The CarPlay Simulator connects to your device and displays the CarPlay interface

Enable Extra Options:

defaults write com.apple.iphonesimulator CarPlayExtraOptions -bool YES

This enables additional options including screen size selection and cluster display settings.

Navigation Screen Sizes for Testing:

Screen Size	Scale
748 × 456	@2x
800 × 480	@2x
960 × 540	@2x
1024 × 600	@2x
1080 × 600	@2x
1280 × 720	@2x
900 × 1200	@3x

Simulator Features:

• Test all CarPlay templates and UI elements
• Simulate day/night modes (automatic based on system dark mode)
• Test different screen sizes and aspect ratios
• Simulate Siri interactions and voice commands
• Test connection/disconnection scenarios
• Test instrument cluster rendering (with extra options enabled)

Limitations:

• Cannot test actual vehicle integration
• Limited testing of physical controls (knobs, touchscreens)
• Some vehicle-specific features unavailable
• Audio routing may differ from actual vehicles

Best Practice: Always test in the simulator first across multiple screen sizes, then verify in a physical vehicle or CarPlay-compatible head unit before release.

Navigation

See the references/ directory for detailed API documentation organized by category:

• references/api_reference.md - Api Reference
• references/communication.md - Communication
• references/dashboard.md - Dashboard and Instrument Cluster
• references/developer_guide.md - Developer Guide (categories, walkthroughs, testing, publishing)
• references/getting_started.md - Getting Started
• references/navigation.md - Navigation
• references/poi.md - Poi
• references/templates.md - Templates
• references/ui_elements.md - Ui Elements

Best Practices

• Scene Management: Implement CPTemplateApplicationSceneDelegate to handle CarPlay connection
• Template Limits: Respect maximum item counts (CPListTemplate: 12 sections, CPGridTemplate: 8 buttons)
• Template Depth Limits: Audio, communication, navigation, parking, and EV charging apps: max 5 templates deep. Food ordering, fueling, driving task, public safety, and voice-based: max 3 templates deep.
• Image Sizes: Follow recommended image sizes for templates and UI elements (see Assets Size Guide)
• Dynamic Updates: Use update methods (updateSections, updateButtons) to refresh content
• Navigation Hierarchy: Use push/pop for navigation, present for modals
• Audio Session Management: Configure AVAudioSession appropriately — .playback for audio apps, .voicePrompt mode for navigation voice prompts. Deactivate when done.
• File Protection: Use .completeUntilFirstUserAuthentication for files needed while iPhone is locked
• Notifications: Only enable .allowInCarPlay for driving-relevant notification categories. Keep content brief.
• Error Handling: Gracefully handle failures and provide user feedback

Common Patterns

Basic List Template

// Create list items
let item1 = CPListItem(text: "Song Title", detailText: "Artist Name")
item1.handler = { item, completion in
    // Handle selection
    completion()
}

// Create section and template
let section = CPListSection(items: [item1, item2])
let listTemplate = CPListTemplate(title: "My Playlist", sections: [section])

// Set as root
interfaceController.setRootTemplate(listTemplate, animated: true)

Navigation with Map Template

// Create map template
let mapTemplate = CPMapTemplate()
mapTemplate.mapDelegate = self

// Show trip preview
let trip = CPTrip(/* route data */)
mapTemplate.showTripPreviews([trip], textConfiguration: nil)

// Start navigation
let navigationSession = mapTemplate.startNavigationSession(for: trip)
navigationSession.upcomingManeuvers = [maneuver1, maneuver2]

Tab Bar Template

// Create root templates for each tab
let musicTab = CPListTemplate(title: "Music", sections: [musicSection])
musicTab.tabTitle = "Music"
musicTab.tabImage = UIImage(systemName: "music.note")

let podcastsTab = CPListTemplate(title: "Podcasts", sections: [podcastSection])
podcastsTab.tabTitle = "Podcasts"
podcastsTab.tabImage = UIImage(systemName: "mic")

// Create tab bar
let tabBarTemplate = CPTabBarTemplate(templates: [musicTab, podcastsTab])
interfaceController.setRootTemplate(tabBarTemplate, animated: false)

Now Playing Template

// Configure Now Playing buttons
let playButton = CPNowPlayingPlaybackRateButton()
let skipButton = CPNowPlayingSkipButton(handler: { _ in
    // Skip to next track
})

CPNowPlayingTemplate.shared.updateNowPlayingButtons([playButton, skipButton])
CPNowPlayingTemplate.shared.isUpNextButtonEnabled = true

Sports Mode for Live Events (iOS 18.4+)

// Create team logos
let homeTeamLogo = CPNowPlayingSportsTeamLogo(teamLogo: UIImage(named: "home_logo")!)
let awayTeamLogo = CPNowPlayingSportsTeamLogo(teamInitials: "VIS")

// Create teams with scores and possession
let homeTeam = CPNowPlayingSportsTeam(
    name: "Home Team",
    logo: homeTeamLogo,
    teamStandings: "1st Place",
    eventScore: "21",
    possessionIndicator: .solid,  // Home team has possession
    favorite: true
)

let awayTeam = CPNowPlayingSportsTeam(
    name: "Away Team",
    logo: awayTeamLogo,
    teamStandings: "2nd Place",
    eventScore: "17",
    possessionIndicator: nil,  // No possession
    favorite: false
)

// Create game clock (counting down from 15:00)
let gameClock = CPNowPlayingSportsClock(
    timeRemaining: 15 * 60,  // 15 minutes in seconds
    paused: false
)

// Create event status with status text and clock
let eventStatus = CPNowPlayingSportsEventStatus(
    eventStatusText: ["3rd Quarter", "4th Down", "Goal Line"],
    eventStatusImage: UIImage(named: "field_position"),
    eventClock: gameClock
)

// Create sports mode
let sportsMode = CPNowPlayingModeSports(
    leftTeam: homeTeam,
    rightTeam: awayTeam,
    eventStatus: eventStatus,
    backgroundArtwork: UIImage(named: "stadium_background")
)

// Set as active now playing mode
CPNowPlayingTemplate.shared.nowPlayingMode = sportsMode

// Update clock during game (e.g., every second)
Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { _ in
    // Update time remaining
    let newClock = CPNowPlayingSportsClock(
        timeRemaining: getCurrentGameTime(),
        paused: isGamePaused()
    )

    // Update event status with new clock
    let updatedStatus = CPNowPlayingSportsEventStatus(
        eventStatusText: eventStatus.eventStatusText,
        eventStatusImage: eventStatus.eventStatusImage,
        eventClock: newClock
    )

    // Refresh sports mode
    let updatedMode = CPNowPlayingModeSports(
        leftTeam: homeTeam,
        rightTeam: awayTeam,
        eventStatus: updatedStatus,
        backgroundArtwork: sportsMode.backgroundArtwork
    )

    CPNowPlayingTemplate.shared.nowPlayingMode = updatedMode
}

Navigation with Maneuvers

// Create maneuvers for turn-by-turn guidance
let maneuver = CPManeuver()
maneuver.instructionVariants = ["Turn right onto Main Street"]
maneuver.symbolImage = UIImage(named: "turn-right")
maneuver.initialTravelEstimates = CPTravelEstimates(
    distanceRemaining: Measurement(value: 500, unit: UnitLength.meters),
    timeRemaining: 60
)

// Add lane guidance
let lane1 = CPLane(angles: [.left, .straight])
lane1.status = .recommended
let lane2 = CPLane(angles: [.straight, .right])
lane2.status = .preferred
maneuver.linkedLaneGuidance = CPLaneGuidance(lanes: [lane1, lane2], instructionVariants: ["Use right lane"])

// Add maneuver to navigation session
navigationSession.upcomingManeuvers = [maneuver]

Attributed Instructions with Images

// Create attributed instruction with embedded image
let instruction = NSMutableAttributedString(string: "Turn right on Apple Park Way")

// Attach an image icon
let image = UIImage(systemName: "arrow.turn.up.right")!
let attachment = NSTextAttachment(image: image)
let imageString = NSAttributedString(attachment: attachment)
instruction.append(NSAttributedString(string: " "))
instruction.append(imageString)

// Create maneuver with attributed instruction
let maneuver = CPManeuver()
maneuver.attributedInstructionVariants = [instruction]

// Also set dashboard-specific attributed instructions
let dashboardInstruction = NSMutableAttributedString(string: "Turn Right ")
let dashboardImage = UIImage(systemName: "arrow.turn.up.right.circle.fill")!
let dashboardAttachment = NSTextAttachment(image: dashboardImage)
dashboardInstruction.append(NSAttributedString(attachment: dashboardAttachment))
dashboardInstruction.append(NSAttributedString(string: " Apple Park Way"))

maneuver.dashboardAttributedInstructionVariants = [dashboardInstruction]

// Set symbol image for main display
maneuver.symbolImage = UIImage(named: "turn-right")

// Add to navigation session
navigationSession.upcomingManeuvers = [maneuver]

Route Selection

// Create route choices for trip preview
let fastRoute = CPRouteChoice(
    summaryVariants: ["Via Highway - 25 min"],
    additionalInformationVariants: ["Fastest route"],
    selectionSummaryVariants: ["Take the highway"]
)

let scenicRoute = CPRouteChoice(
    summaryVariants: ["Via Scenic Road - 35 min"],
    additionalInformationVariants: ["No tolls"],
    selectionSummaryVariants: ["Take the scenic route"]
)

let trip = CPTrip(
    origin: originMapItem,
    destination: destinationMapItem,
    routeChoices: [fastRoute, scenicRoute]
)

mapTemplate.showTripPreviews([trip], textConfiguration: nil)
