CarPlay CPListImageRowItem causes Inverted Scrolling and Side Button malfunction
In my CarPlaySceneDelegate.swift, I have two tabs: The first tab uses a CPListImageRowItem with a CPListImageRowItemRowElement. The scroll direction is inverted, and the side button does not function correctly. The second tab uses multiple CPListItem objects. There are no issues: scrolling works in the correct direction, and the side button behaves as expected. Steps To Reproduce Launch the app. Connect to CarPlay. In the first tab, scroll up and down, then use the side button to navigate. In the second tab, scroll up and down, then use the side button to navigate. As observed, the scrolling behavior is different between the two tabs. Code Example: import CarPlay import UIKit class CarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate { var interfaceController: CPInterfaceController? func templateApplicationScene( _ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController ) { self.interfaceController = interfaceController downloadImageAndSetupTemplates() } func templateApplicationScene( _ templateApplicationScene: CPTemplateApplicationScene, didDisconnectInterfaceController interfaceController: CPInterfaceController ) { self.interfaceController = nil } private func downloadImageAndSetupTemplates() { let urlString = "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRcYUjd1FYkF04-8Vb7PKI1mGoF2quLPHKjvnR7V4ReZR8UjW-0NJ_kC7q13eISZGoTCLHaDPVbOthhH9QNq-YA0uuSUjfAoB3PPs1aXQ&s=10" guard let url = URL(string: urlString) else { setupTemplates(with: UIImage(systemName: "photo")!) return } URLSession.shared.dataTask(with: url) { [weak self] data, _, _ in let image: UIImage if let data = data, let downloaded = UIImage(data: data) { image = downloaded } else { image = UIImage(systemName: "photo")! } DispatchQueue.main.async { self?.setupTemplates(with: image) } }.resume() } private func setupTemplates(with image: UIImage) { // Tab 1 : un seul CPListImageRowItem avec 12 CPListImageRowItemRowElement let elements: [CPListImageRowItemRowElement] = (1...12).map { index in CPListImageRowItemRowElement(image: image, title: "test \(index)", subtitle: nil) } let rowItem = CPListImageRowItem(text: "Images", elements: elements, allowsMultipleLines: true) rowItem.listImageRowHandler = { item, elementIndex, completion in print("tapped element \(elementIndex)") completion() } let tab1Section = CPListSection(items: [rowItem]) let tab1Template = CPListTemplate(title: "CPListImageRowItemRowElement", sections: [tab1Section]) // Tab 2 : 12 CPListItem simples let tab2Items: [CPListItem] = (1...12).map { index in let item = CPListItem(text: "Item \(index)", detailText: "Detail \(index)") item.handler = { _, completion in print("handler Tab 2") completion() } return item } let tab2Section = CPListSection(items: tab2Items) let tab2Template = CPListTemplate(title: "CPListItem", sections: [tab2Section]) // CPTabBarTemplate avec les deux tabs let tabBar = CPTabBarTemplate(templates: [tab1Template, tab2Template]) interfaceController?.setRootTemplate(tabBar, animated: true) } } Here is a quick video:

CarPlay: Can third-party audio apps add a Search/Siri button next to the Now Playing button like Apple Music?
Hi, In Apple Music on CarPlay, there is a Search button shown next to the Now Playing (NPS) button in the top navigation bar. Tapping this Search button activates Siri voice search. I want to understand: Does CarPlay allow third-party audio apps to add a similar Search button in the top bar (next to the Now Playing button)? Which can be used to trigger Siri from the screen UI (not steering-wheel button or “Hey Siri”)? Is there any supported approach for screen-based Siri activation other than the guidance here: https://developer.apple.com/documentation/carplay/cplisttemplate#Integrating-Siri-Into-Your-Template-App Basically, is the Apple Music search/Siri button a publicly available CarPlay capability, or is it system-reserved?

IOS 26.4 Beta 1 CarPlay Smart Zoom
I just installed IOS 26.4 Beta 1 and on my 2023 Ram i get the Edit Pages option on the bottom. This happened when I first installed IOS 26 and the solution was to go to Display settings in CarPlay and turn off the Smart Zoom. After this latest install the Edit Pages is back and I no longer have the Smart Zoom option to turn off

Car Play Entitlement
Hi, I’m working on a proof of concept for a CarPlay application where I need to display multiple Points of Interest, such as EV charging stations and fuel stations. The app will also allow users to book a selected Point of Interest (for example, an EV charging slot). I understand that the app can be registered under the Navigation (turn‑by‑turn) category, but I wanted to check whether it is also possible to register it under the Driving Task category. I also want to know if i can Register for multiple Categories for my car play application.

Memory leak in CarPlay when using CPListImageRowItem
Memory leak in CarPlay when using CPListImageRowItem. The following behavior was observed in the CPListTemplate class when using CPListImageRowItem: If a CPListImageRowItem cell is inserted into the screen, the screen starts to leak, even if it contains no elements (CPListImageRowItem(titleList: nil, imagesRow: [], titlesRow: []). Replacing CPListImageRowItem with CPListItem stops the leak. Using the new initializer for iOS 26 does not correct the issue; the screen still leaks. Class reference: https://developer.apple.com/documentation/carplay/cplistimagerowitem

CPContactTemplate does not display buttons iOS26
I'm trying to display CPButtons (CPContactCallButton, CPContactMessageButton) in CPContactTemplate. They are displayed using device with iOS16, but with iOS26 device CPContactTemplate only displays contact image and contact name. No buttons. Is it a bug? I don't have iOS17/18 devices to try.

Memory leak in CarPlay when using CPTabBarTemplate
Memory leak in CarPlay when using CPTabBarTemplate Reproduced using the code example "Integrating CarPlay with Your Music App" from the official Apple documentation - https://developer.apple.com/documentation/carplay/integrating-carplay-with-your-music-app Steps to reproduce the leak: Download and run the example on CarPlay. Select the Settings tab. Click the first item in the list "Use Apple Music". Click Back button. Repeat steps 3 and 4 several times. Open Debug Memory Graph in xCode and search for "CPGridTemplate" - the count will be greater than 0. Conditions under which the memory leak disappears: If you open and switch to all tabs one by one, the leak disappears.

CarPlay on iOS 14 and iOS 15
My app developed with the new Xcode 26 doesn't appear on CarPlay when running on iOS 14–15 devices. My developer has obtained the com.apple.developer.carplay-driving-task permission, but iOS 16+ devices allow my app to display on CarPlay. Can anyone help resolve this issue? Is it because the carplay-driving-task permission is only available for iOS 16+ devices? If I want compatibility with iOS 14–15 devices, do I need to apply to Apple for the carplay-audio permission to use it? Has anyone encountered a similar issue? Thanks!

CarPlay navigation issue, maximum depth
Hi everyone, I am working on a CarPlay integration, and need open a two level list opened from a root template. However, I am always receiving an error message when opening the 2nd pushed template. To narrow it down not to have an issue with some app specific code I created the CarPlay scene below. I am aware that there is a limit, but two levels I understand are supported on all CarPlay integrations, the maximum seems to be 5. The app is just crashing right after showing the 2nd template. Any ideas? Any hints are much appreciated. Thanks a lot! Regards, Michael class CarPlaySceneDelegate2: UIResponder, CPTemplateApplicationSceneDelegate { // [...] private func createRootTemplate() -> CPListTemplate { let pushToAItem = CPListItem(text: "Push to Template A", detailText: "Level 1 → Level 2") pushToAItem.handler = {[weak self] (pushToAItem, completion) in guard let self = self else { completion() return } self.interfaceController?.pushTemplate( self.pushTemplateA(), animated: true, completion: { (didPresent, error) in completion() } ) } let section = CPListSection(items: [pushToAItem]) let template = CPListTemplate(title: "Root Template", sections: [section]) return template } private func pushTemplateA() -> CPListTemplate { let pushToBItem = CPListItem(text: "Push to Template B", detailText: "Level 2 → Level 3") pushToBItem.handler = {[weak self] (pushToBItem, completion) in guard let self = self else { completion() return } self.interfaceController?.pushTemplate( self.pushTemplateB(), animated: true, completion: { (didPresent, error) in completion() } ) } let backToRootItem = CPListItem(text: "Pop to Root", detailText: "Go back to root") backToRootItem.handler = { [weak self] _, completion in self?.interfaceController?.popToRootTemplate(animated: true, completion: nil) completion(); } let infoItem = CPListItem(text: "Current Depth", detailText: "2 (Template A)") let stackCountItem = CPListItem( text: "Stack Count", detailText: "\((interfaceController?.templates.count ?? 0) + 1)" ) let section = CPListSection(items: [pushToBItem, backToRootItem, infoItem, stackCountItem]) let template = CPListTemplate(title: "Template A", sections: [section]) return template } private func pushTemplateB() -> CPListTemplate { let pushToCItem = CPListItem(text: "Push to Template C", detailText: "Level 3 → Level 4") pushToCItem.handler = {[weak self] (pushToCItem, completion) in guard let self = self else { completion() return } self.interfaceController?.pushTemplate( self.pushTemplateC(), animated: true, completion: { (didPresent, error) in completion() } ) } let backToRootItem = CPListItem(text: "Pop to Root", detailText: "Go back to root") backToRootItem.handler = { [weak self] _, completion in self?.interfaceController?.popToRootTemplate(animated: true, completion: nil) completion() } let popOneItem = CPListItem(text: "Pop One", detailText: "Go back to Template A") popOneItem.handler = { [weak self] _, completion in self?.interfaceController?.popTemplate(animated: true, completion: nil) completion() } let infoItem = CPListItem(text: "Current Depth", detailText: "3 (Template B)") let stackCountItem = CPListItem( text: "Stack Count", detailText: "\((interfaceController?.templates.count ?? 0) + 1)" ) let section = CPListSection(items: [pushToCItem, popOneItem, backToRootItem, infoItem, stackCountItem]) let template = CPListTemplate(title: "Template B", sections: [section]) return template } private func pushTemplateC() -> CPListTemplate { let backToRootItem = CPListItem(text: "Pop to Root", detailText: "Go back to root") backToRootItem.handler = { [weak self] _, completion in self?.interfaceController?.popToRootTemplate(animated: true, completion: nil) completion() } let popOneItem = CPListItem(text: "Pop One", detailText: "Go back to Template B") popOneItem.handler = { [weak self] _, completion in self?.interfaceController?.popTemplate(animated: true, completion: nil) completion() } let infoItem = CPListItem(text: "Current Depth", detailText: "4 (Template C)") let stackCountItem = CPListItem( text: "Stack Count", detailText: "\((interfaceController?.templates.count ?? 0) + 1)" ) let section = CPListSection(items: [popOneItem, backToRootItem, infoItem, stackCountItem]) let template = CPListTemplate(title: "Template C", sections: [section]) return template } }

AVSpeechSynthesizer & Bluetooth Issues
Hello, I have a CarPlay Navigation app and utilize the AVSpeechSynthesizer to speak directions to a user. Everything works great on my CarPlay simulator as well as when plugged into my GMC truck. However, I found out yesterday that one of my users with a Ford truck the audio would cut in an out. After much troubleshooting, I was able to replicate this on my own truck when using Bluetooth to connect to CarPlay. My user was also utilizing Bluetooth. Has anyone else experienced this? Is there a fix to the problem? import SwiftUI import AVFoundation class TextToSpeechService: NSObject, ObservableObject, AVSpeechSynthesizerDelegate { private var speechSynthesizer = AVSpeechSynthesizer() static let shared = TextToSpeechService() override init() { super.init() speechSynthesizer.delegate = self } func configureAudioSession() { speechSynthesizer.delegate = self do { try AVAudioSession.sharedInstance().setCategory(.playback, mode: .voicePrompt, options: [.mixWithOthers, .allowBluetooth]) } catch { print("Failed to set audio session category: \(error.localizedDescription)") } } func speak(_ text: String) { Task(priority: .high) { let speechUtterance = AVSpeechUtterance(string: text) speechUtterance.voice = AVSpeechSynthesisVoice(language: AVSpeechSynthesisVoice.currentLanguageCode()) try AVAudioSession.sharedInstance().setActive(true, options: .notifyOthersOnDeactivation) speechSynthesizer.speak(speechUtterance) } } func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didFinish utterance: AVSpeechUtterance) { Task { stopSpeech() try AVAudioSession.sharedInstance().setActive(false) } } func stopSpeech() { speechSynthesizer.stopSpeaking(at: .immediate) } }

CarPlay CPGridTemplate corrupt items
For some reason, Carplay 18.x works fine, however in under certain situations in our app, Carplay 26.x breaks. The expected grid layout should be : However, this is what we see in some cases when we update our templates. I have not been able to isolate the cause of this issue. Has anyone ever seen this happen on their CarPlay apps and discovered the cause? The data sets fed into the templates are identical, the difference is in some of the timing and update order...

Does Carplay work in Enterprise apps?
I am developing CarPlay addition on our app. Which is distributed with the Enterprise In distribution method, so we do not have a product in the App Store. I am wondering if CarPlay support can be provided in applications distributed with the Enterprise in distribution method? If this is not possible, I will inform management that this is not possible. I am waiting for your answers, thanks.
