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) { } } }

I remember this integration being demoed at WWDC25. Ability to trigger app intent for iOS application from Spotlight search on MacOS. How Do I extend my iOS Application to be able to do this? Where is the documentation for implementing this mechanism? Thank you in advance for your help. I believe this integration is a powerful productivity unlock!

To whom it may concern that deals with bugs in SwiftUI for iOS 26: Inadvertently discovered a bug which duplicates ToolbarItem in any placement in the toolbar when navigationBarBackButtonHidden is set to true. .toolbar{ ToolbarItem(placement: .confirmationAction) { Button("Stop", systemImage: "stop.fill"){ //some action } } } .navigationBarBackButtonHidden(true) Expected Behavior Show the ToolbarItem Actual Behavior Duplicates items in the placement position. Thank you.

Hello, I am new application developer that has been developing several applications in the productivity and finance sections concurrently for about 1 year. One of my applications is nearly ready to be submitted to the App Store. I have received a lot of discouragement from people who have submitted apps in regards to putting submitting as a paid app, however due to all of the upfront and ongoing investment I've made, I do not wish to release my application for free initially. (I am learning how to best integrate storekit and in-app purchases and subscriptions, but I'm not ready to implement that yet) QUESTION: When releasing an app as a paid app and then converting to a FREE app with subscription later on, is there anything I need to be aware of technically or in regards to guidelines so I don't shoot myself in the foot when changing pricing? Any advice is greatly appreciated. Thank you.

How do I set a custom icon for an app control that appears in Control Shortcuts (swipe down from iOS) ? Where is the documentation for size and where to put the image, format etc? Thank you. Working Code (sfsymbol) import Foundation import AppIntents import SwiftUI import WidgetKit // MARK: - Open App Control @available(iOS 18.0, *) struct OpenAppControl: ControlWidget { let kind: String = "OpenAppControl" var body: some ControlWidgetConfiguration { StaticControlConfiguration(kind: kind, content: { ControlWidgetButton(action: OpenAppIntent()) { Label("Open The App", systemImage: "clock.fill") } } }) .displayName("Open The App") // This appears in the shortcuts view } } Sample Image These apps use their own image. How can I use my own image?
