What's the guidance on submitting new builds for App Review that include support for iPhone Duo/iPhone resizability? Will they work when building with Xcode 27 + if available for 27.1 or do we have to wait for new Xcode release? Any guidance from Apple and timeframe on build submission if our updates are ready and undergoing testing in simulator? Thank you.

I am unable to dismiss Voice Control Siri AI bubble when enabling Voice Control in iOS 27. Can someone from accessibility team provide guidance on how to dismiss without touching the screen in the activation flow? Siri bubble remains on screen... Thank you, and appreciate all the work you do. Voice Control is an amazing capability system wide.

Just download 27.1 and Device Hub 27.1 and unable to locate the iPhone Duo simulator. Please help what are the steps to get this? I have both Xcode 27 and Xcode 27.1 installed. Launched 27.1 does not have Duo sim and all test devices in providing incompatible... What are the exact steps for testing an existing app with compatibility with 27.1 iPhone Duo? Thank you.

I'm building an accessibility feature where a user walks around and taps NFC tags to trigger updates in the app (e.g., wayfinding/context info). I want a "Live Mode" toggle that keeps the app listening for NFC reads continuously while it's on, processing each tag as it's scanned, rather than one-shot read-and-dismiss. Is there a Core NFC API or session configuration that supports this kind of continuous/persistent listening, or does every read still require invalidating and restarting the session afterward? Currently: I have high-performant reads working reliably with passive NDEF/tag detection. What I'm trying to figure out: Recommended approach — should I keep a single long-lived NFCReaderSession alive and handle repeated reads within it, or restart a new session immediately after each read? VoiceOver / accessibility — how does the system NFC sheet interact with VoiceOver, especially if the session is restarting frequently while the user is mid-walk? Session timeout and restart handling — what's the best way to detect and recover from a session timing out or invalidating unexpectedly, without the user noticing a gap in "Live Mode"? Battery/radio use — are there known concerns with keeping NFC polling active over an extended period (minutes, not seconds)? Thank you.

I’m preparing my existing App Store app for iOS 27 and want to test interface resizability on iPhone Duo. I cannot find the iPhone Duo simulator in Device Hub. Is it currently available? If so, what Xcode version/runtime is required and how do I add it? Thanks! I have the latest Xcode 27 from downloads section and Device Hub 27. Where is 27.1 download?

AirPlay fails when Mac is connected to iPhone Personal Hotspot I’m using AVRoutePickerView to route audio from an iPhone app to a Mac with AirPlay Receiver enabled. What works When the iPhone and Mac are connected to the same Wi-Fi network, AirPlay routing works normally. Routing audio back to the iPhone speaker or to connected AirPods over Bluetooth also works correctly. What fails When the iPhone provides a Personal Hotspot and the Mac connects to that iPhone’s hotspot, the Mac still appears as an available destination in AVRoutePickerView. However, selecting the Mac fails with: Unable to connect to “[Mac Name]” Questions Is AirPlay routing from an iPhone hosting a Personal Hotspot to a Mac connected to that hotspot a supported network topology? If it is supported, are there any additional AVAudioSession, networking, entitlement, or AirPlay configuration requirements for this scenario? The fact that the Mac is successfully discovered and displayed by AVRoutePickerView, but the connection itself fails, is the part I’m particularly trying to understand. Thank you for any guidance on the expected behavior here.

Let's say I'm in Notes, or in Pages, or in Files or Live Text if I'm in Photos... will Siri AI be able to COPY the text for me if I ask it to do so? If you have new Siri AI installed, or are DTS Engineer at Apple I'd appreciate a yes/no? Critical for text editing, working with AI output, and general modern work requirements. Presently I have to press the "share" button then select Copy from the Share Sheet, OR in Pages I have to select EXPORT from the More Menu and choose Plain Text to get the contents. Thank you. Be well.

I'm building an iOS app in SwiftUI and need to adapt my UI when Voice Control is active — specifically to show labels on custom gesture-driven controls so they're accessible via Voice Control commands. I've checked UIAccessibility and can find notifications and properties for VoiceOver (isVoiceOverRunning), Switch Control (isSwitchControlRunning), and AssistiveTouch (isAssistiveTouchRunning), but I can't find any equivalent for Voice Control. UIAccessibility.isVoiceControlRunning and voiceControlStatusDidChangeNotification appear to exist on macOS (AXIsProcessTrustedWithOptions) but not on iOS. Questions: Is there a public iOS API to detect whether Voice Control is currently active — either a UIAccessibility property, notification, or SwiftUI environment value? If not, is the recommended approach to use UIAccessibility.isGuidedAccessEnabled as a proxy, or something else entirely? Is there a private entitlement or capability that unlocks this detection for App Store apps? What I've already tried: Checking AccessibilityFeatures environment values in SwiftUI (@Environment(.accessibilityReduceMotion) etc.) Thanks!

What is the best way to represent (in-app) or via App Store screenshots integration with native apps like Notes, Files, Photos? From a design perspective is it better to just use the app icon and say "integrated with... " subtitle or is there specific guidance from Apple on how to do this. A use case within my app is during onboarding I'd like to show that my app can be accessed via Control Center from any app like Notes, Photos, or Action Button. Thank you.

What should we know about testing the new Siri and beta software on iPad vs iPhone if we do not have a space 17 PRO device for beta software testing? And can the new Siri AI be activated on an iPad? Any requirements? Any other testing options? Thank you.

Since my questions were never answer and no replies during the group lab, I'm posting them here: When does vapor chamber cooling activate on the new iPhone 17 Pro devices? Does the system handle the cooling in those scenarios, can developer activate it? Does volume level affect performance/battery? Can you discuss bluetooth connections to AirPods Pro 3/AirPods Pro Max and impact on battery? Is there an API to detect thermal changes and what are UI changes that can reduce thermal impact when app is in background and foreground? Whats the best way to profile Power usage and battery drain when an application is processing, working in background and multimodal? Thank you.

Didn't know these would be published on the Apple Developer YouTube channel, these are great if you have scheduling conflicts in attending live. Thanks dev team!

It would be a wonderful idea for the Apple Developer Team to open up the developer center and host events like Keynote (in the theatre) and interfacing with Apple Engineers for those developers who want to be in Cupertino but did not win a ticket. Thank you.

Whats to code to warm it up once? Saw this in a developer video but cannot find it. Prevent cold run within an application. Thank you in advance!

inline-code How do you achieve this effect in toolbar? Where is the documentation for this? How to make it appear top toolbar or bottom toolbar? Thank you! Here is what I have now... .toolbar { ToolbarItem(placement: .destructiveAction) { Button { showConfirm = true } label: { Image(systemName: "trash") .foregroundColor(.red) } } } .confirmationDialog( "Are you sure?", isPresented: $showConfirm, titleVisibility: .visible ) { Button("Delete Item", role: .destructive) { print("Deleted") } Button("Archive", role: .none) { print("Archived") } Button("Cancel", role: .cancel) { } } }
