Age range permission prompt text configurability
For other permission prompts in the iOS ecosystem, we have the option to configure the text shown in the prompt via keys in the Info.plist. This does not appear to be the case with regards to the age range permission prompt. The text of the prompt implies the app includes a differentiated experience for child or teen content and that confirming age unlocks more features (making it seem optional for using the app). Is there a plan for app developers to be able to update that permission prompt similarly to how we can configure others? If so, is there any timeline we can expect that on?

Best practice for using a single EKEventStore instance across threads?
Hello, Regarding EKEventStore, the WWDC session mentions that “you should only have one of these for your application.” In my app, I need to use the instance on both the main thread and a background thread, and I would like to share a single instance across them. However, EKEventStore is a non-sendable type, so it cannot be shared across different isolation domains. I would like to know what the recommended best practice is for this situation. Also, do I need to protect the instance from data races by using a lock? Thank you.

CallKit VoIP → App launch → Auto WebRTC/MobileRTC connection: Does Apple allow this flow?
Our app receives a CallKit VoIP call. When the user taps “Answer”, the app launches and automatically connects to a real-time audio session using WebRTC or MobileRTC. We would like to confirm whether the following flow (“CallKit Answer → app opens → automatic WebRTC or MobileRTC audio session connection”) complies with Apple’s VoIP Push / CallKit policy. In addition, our service also provides real-time video-class functionality using the Zoom Meeting SDK (MobileRTC). When an incoming CallKit VoIP call is answered, the app launches and the user is automatically taken to the Zoom-based video lesson flow: the app opens → the user is landed on the Zoom Meeting pre-meeting room → MobileRTC initializes immediately. In the pre-meeting room, audio and video streams can already be active and MobileRTC establishes a connection, but the actual meeting screen is not joined until the user explicitly taps “Join”. We would like to confirm whether this flow for video lessons (“CallKit Answer → app opens → pre-meeting room (audio/video active) → user taps ‘Join’ → enter actual meeting”) is also compliant with Apple’s VoIP Push and CallKit policy.

How to debug a CoreSpotlight extension?
My CoreSpotlight extension seems to exceed the 6 MB memory limit. What’s the best way to debug this? I've tried to attach the debugger on the Simulator but the extension seems to be never launched when I trigger the reindex from Developer settings. Is this supposed to work? On device, I am able to attach the debugger. However, I can neither transfer the debug session to Instruments, nor display the memory graph. So I've no idea how the memory is used. Any recommendations how to move forward? Is there a way to temporarily disable the memory limit since even with LLDB attached, the extension is killed.

AppleTV returns to homescreen overnight
Hi We have an AppleTV app that is used to continuously display information (digital signage). One of our clients reports that their AppleTV returns to the homescreen by morning. While our recommendation is to setup Mobile Device Management to lock the AppleTV into running only our app, not every client will have the IT knowledge to set this up. So we're trying to figure out possible causes for the app getting closed. We've not received any crash reports, nor does the device give any indication the app crashed. The energy saving settings are set to run continuously without sleep. The client is reporting this happens every night, so it seems unlikely to be caused by tvOS updates. Are there other things I could rule out to find the cause of this issue? Any ideas are welcome, thanks!

The enterprise app crashes.
I created a new project, packaged it with my own enterprise certificate, installed and used it. There were no problems on most devices. However, on some devices with system versions of 18.3 and 18.4, the app crashes when opened after trusting the certificate. It seems that there is something wrong with the certificate, but I have confirmed that the certificate is fine. May I ask what the cause of this issue is?

WeatherKit failing on JWT Error
My app AirCompare has been in the app store and successfully using WeatherKit to fetch weather since it became available. Now some (not all) users are encountering the following errors: Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Encountered an error when fetching weather data subset; location=<+42.40865786,-88.96911526> +/- 0.00m (speed -1.00 mps / course -1.00) @ 6/23/25, 2:56:47 PM Central Daylight Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Others are reporting this same problem here in the forums.

PDFKit Sizes increases
Hey there, I have a slight problem which is also known on the web, but I couldn't find any answers... My iOS App is working with documents like pdf and images. It is made to handle invoices and upload them to an external service. The app's job is to compress those pdfs and images. Sadly the PDFKit's PDFDocument increases its size just after importing it with pdfDocument = PDFDocument(url: url) and later exporting it to an pdf file again with data = pdf.dataRepresentation() without ever modifying it. It increases by server KB after each export. Do you have any alternatives to the renderer dataRepresentation() or a general PDFKit alternative Thanks

Xcode 16.2 App Crashes Due to Missing NSMotionUsageDescription Key in Info.plist
There is a crash while running the project in Xcode 16.2. The project has been using CMPedometer and CoreMotion since 2020. I wonder: I did not have the NSMotionUsageDescription key added, why is it mandatory to add this key now? “This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSMotionUsageDescription key with a string value explaining to the user how the app uses this data.”

Access resource in swift package from xcframework
I have an iOS app that includes a local Swift package. This Swift package contains some .plist files added as resources. The package also depends on an XCFramework. I want to read these .plist files from within the XCFramework. What I’d like to know is: Is this a common or recommended approach—having resources in a Swift package and accessing them from an XCFramework? Previously, I had the .plist files added directly to the main app target, and accessing them from the XCFramework felt straightforward. With the new setup, I’m trying to determine whether this method (placing resources in a Swift package and accessing them from an XCFramework) is considered good practice. For context: I am currently able to read the .plist files from the XCFramework by passing Bundle.module through one of the APIs exposed by the XCFramework.

About AppShortcuts limit
I developed a shortcut feature for my app using the AppIntents framework, which can display a maximum of 10 shortcuts in the Shortcuts app. However, I've noticed that apps like Tesla and Porsche have a significantly larger number of shortcuts, far exceeding 10. After searching online, I found that they might be using Intent Extensions and the SiriKit framework. I customized an Intent through SiriKit, checked the option for "Intent is user-configurable in the Shortcuts app" and "Add to Siri." I can find this shortcut when I search for it, but it does not appear on the homepage or under the app category. Is there any way to resolve this?

The menu can't be shown in background process in MacOS 26(beta)
After I upgraded to MacOS 26(beta), my program caused the system to pop up a window as shown in the following picture. My application is a process with only a tray icon. I found that my tray icon is not displayed in the current version, even though I clicked the "Always Allow" button. Here are my questions: 1.Will this related feature remain consistent in the official release? 2.How can I create a cmd process that only displays a system tray icon (no main window) like Alfred?

TipKit popover Issues...
I have been trying to use TipKit popovers in my App. They all behave as expected in the simulator but on a real device I am seeing some strange behaviors. I have a couple of instances of where the tip is displaying an entire sheet instead of just the popover. In another case I cannot dismiss the Tip. Has anyone seen these behaviors and are there known issues/workarounds for this? I am reluctant to use something that works perfectly in the simulator but gives unpredictable results on a device. Not a good user experience in my opinion.

Updating Advanced App Clip Experience in Apple Store Connect Not Working
When updating an existing advanced app clip experience, the change doesn't actually apply. It shows the correct image in the UI, but when you use the app clip it shows the old image. Looking into it more, the status has "UPDATE_SUBMITTED". Seems related to this issue (https://developer.apple.com/forums/thread/810544) and this issue (https://developer.apple.com/forums/thread/810351).

iOS 26 fails to automatically switch to [system settings - personal hotspot ] directly from application ]
The API we used: NSURL *url = [NSURL URLWithString:@"App-Prefs:INTERNET_TETHERING"]; The link provided by Apple engineer: https://developer.apple.com/forums/thread/761314 I did not find any URL in the link that leads to the secondary menu of system settings. Does this suggest that iOS 26 does not support this functionality? Moreover, is it possible that versions of iOS 18 and earlier may also not support this behavior in the future?

CallKit blocked call remains Missed Calls
I’m currently developing a spam number blocking app using CallKit. I’ve confirmed that up to iOS 26 beta 5, there is a bug where number blocking doesn’t work. In my current tests, the ringtone doesn’t sound and the blocking works fine, but the call still appears in the missed calls list, which is bothersome. If the bug is fixed in future versions (as it was in previous versions), is there a way to block the number so that it also does not appear in missed calls?
