Why voice processing enabled on AVAudioInputNode makes output audio noticable lower than without it and how to overcome it using voice processing enabled

My queries are failing in an unusual way. I can query 4 out of 5 Record Types. The 5th fails from the app (CKQueryOperation) and, surprisingly, also from the CloudKit Dashboard. It returns only 100-300 records when it should return over 4000. Tapping "Query Records" returns an additional 100-300 records. Apple Developer Technical Support has suggested that the issue involves the index of the container and wrote that only the CloudKit Team can fix it. So my question is - How do I get the CloudKit Team to fix it????

Subject: Technical Inquiry: Interfacing the Push to Talk Framework with External RF Hardware Modules (CB / Amateur Radio Bands) Dear Apple Engineering Team, We are writing to inquire about the architectural flexibility of the Push to Talk (PTT) framework when integrating iOS and iPadOS devices with external, custom RF hardware accessories. Uart. We are developing a specialized communication system that uses an external transceiver module connected via a secure, wired MFi USB-C connection. Our objective is to utilize the native system UI elements provided by the PTT framework (such as the Lock Screen controls and Dynamic Island overlays) to manage transmissions that are broadcast and received over external analog frequencies—specifically Citizens Band (CB) or licensed Amateur (Ham) Radio bands—rather than a standard cellular IP network. Could you please provide guidance on the following framework capabilities and integration boundaries: 1 Routing Audio to External Hardware Pipelines: Can a ⁠PTChannelManager⁠ instance be configured to pipe its outbound audio buffer stream directly to an external USB-C Core Audio accessory for RF modulation, rather than routing it through an internet-bound network socket? 2 Mapping Hardware Interrupts to ⁠PTChannelTransmitRequestSource⁠: When a user presses a physical push-to-talk button on an external microphone or module connected via USB-C, what is the recommended method to map that hardware interrupt so it registers natively as a system-level transmission request? 3 Handling Unsynchronized Incoming Signals: Traditional VoIP PTT apps rely on an incoming Apple Push Notification (APNs) token to wake the app via ⁠PTPushResult⁠ when someone speaks. In an air-gapped RF environment where an external hardware squelch breaks on an analog frequency, how can the external module signal the iOS device to instantly wake the background thread and initialize a receiving audio session without an internet connection? 4 Compliance and Metadata Constraints: Are there any restrictions within the ⁠PTChannelDescriptor⁠ or ⁠PTParticipant⁠ metadata structures that would prevent us from displaying analog channel frequencies, squelch codes, or Amateur Radio callsigns in place of traditional digital usernames? Thank you for your guidance on how we can best bridge Apple’s modern PTT framework with external radio hardware ecosystems. Best regards, Ken Zakreski co Founder, lead developer

Throughout the years I've done a few integrations at my company with an iOS Application and an identity provider. I've implemented samples with UIWebView, WKWebview, Certificate based authentication through custom URLSession implementations and lastly through ASWebAuthentication. Also I gave the SSO Extension a try, but got stuck at some point (also Apple Forum didn't give me some solution -> https://developer.apple.com/forums/thread/117747) I'm having troubles digging through the Apple resources to find the best approach for big enterprises. We make use of a MDM solution, so I was hoping to find means to 'exploit it' and don't implement any custom authenticationframework anymore. Also, granting SSO between Apps and websites is what my ideal goal would be. Could you point me to some resources that can help me or give me some guidance on which of the frameworks/SDKs to use?

What's the recommended pattern for sharing a complex SpriteKit game scene (and basic game code) between iOS and watchOS targets without code duplication, given the platform differences in input and rendering?

We are deploying Platform SSO using the Secure Enclave authentication method. However, users are still being prompted for their username and password during registration. This undermines our goal of going passwordless and is causing deployment friction with customers. Once the Secure Enclave method is deployed and initialized, is there a way to suppress or skip this password dialog so users only authenticate via hardware/biometrics?

Hello, I created an app using the latest version of Xcode (16.2), and I'm having a problem testing this app on my iPhones. I created this app just like all the others I've made for my clients, including one on (03/24/25), but when I went to upload another App to App Store Connect on (03/26/25) I couldn't test it on my phone. Points to consider: The app runs perfectly on the Emulator. All my terms and agreements with Apple are up to date. I tried to download the apps through Testflight on 2 different devices, iPhone 7 Plus (iOS 15.8.1) and iPhone 15 Pro Max (iOS 18.3.2), and I was unsuccessful in neither attempt. I can send my app to the internal testers, but when I click download, the following message appears: Could not install [APP NAME]. The requested App is not available or doesn't exist. I imagine this problem is with Apple itself, I have already contacted support, but I need to resolve this urgently for my customers. Has anyone experienced this and resolved it?

Are there any mechanisms to troubleshoot or test SiwA server-to-server notifications? I am not seeing any traffic from Apple for user account changes (e.g., revoking authorization for an app), but the URL that I have configured in my account matches my endpoint, it is available from the public internet, and other SiwA functions are working correctly. Any guidance will be appreciated.

Future of Behavioral Authentication on Apple PlatformsWith the rapid advancement of on-device AI and Apple Intelligence, does Apple see a future where user identity can be continuously verified through behavioral patterns and contextual signals rather than relying solely on discrete authentication events such as Face ID, Touch ID, or passcodes? If so, what privacy and security challenges would need to be solved before such an approach could become practical on Apple platforms?

Is there any way to get notified in macOS when the iCloud Drive becomes online/offline so that I can update the UI in my app to reflect that state? Thanks!

Hello, I'm facing an unusual App Store Search issue and would appreciate guidance from Apple staff or developers who have experienced something similar. App Details App Name: Logistos – Logistics Platform Apple ID: 6759841195 Category: Business Availability: Available in all supported storefronts, including India Publicly available for: More than 2 months Latest version: Released and live for more than 5 days Issue The app is accessible through its direct App Store URL and is indexed by Google Search. However, it does not appear in App Store Search results. I have tested the following search terms on multiple devices and storefronts: Logistos Logistos – Logistics Platform Logistos Logistics Platform 6759841195 (Apple ID) In all cases, the app does not appear in the search results. Additional Information The app name contains "Logistos". The subtitle is "Logistics & Shipment Tracking". The keywords include "logistos". Metadata changes have already been released and enough time has passed for propagation. App Store Analytics shows the app is receiving impressions, product page views, and downloads. Direct App Store links work normally. I have already opened a support case with Apple Developer Support. Case ID: 102908696756 Has anyone encountered a similar App Store Search indexing issue? Could this indicate that the app requires manual reindexing by Apple? Any guidance would be greatly appreciated. Thank you.

In the past I ran into issues where the CloudKit client SDK was not attributing network usage in MetricKit. Since MetricKit got a major update this year I’d like to make sure usage goes here agains the app. I would expect transfer metrics to also count for CKSyncEngine, or the CloudKit config for core/swift data too. Is this assumption correct?

We have a managed iOS app, distributed to managed iPhones through Apple Business Manager, and we are offering a TestFlight version. When users install a TestFlight Version, it is relatively quickly replaced by the current release. Is there a way to prevent this?

do you see a future where devices continuously verify a user’s identity through behavioral signals rather than discrete login events?

Hello Albert! I am experiencing some strange bugs around DeviceActivityEvents (part of the DeviceActivity framework) on iOS 26 / iOS 26.1 / iOS 26.2 beta: When creating a DeviceActivityEvent we can assign a threshold and applicationTokens. The idea is, that after the user has spent said threshold on said apps, eventDidReachThreshold() is called. The property includesPastActivity is set to false. On iOS 26 however, it happens (quite reliably after updating to a new beta seed) quite often that eventDidReachThreshold() is called immediately (after a couple of seconds) instead of waiting for the threshold to be met. Is anyone else seeing similar issues on iOS 26 / iOS 26.1 / iOS 26.2 beta? Only workaround I have found is to ask users to revoke and re-grant Screen Time permissions. This only holds for about two weeks though or at most until the next iOS 26 beta update is installed, so it is not a permanent solution unfortunately. Feedback (incl. sysdiagnoses and sample project) is filed under: FB18061981 FB18927456 One of our users has filed their own feedback request as well: FB20817853 Thanks a lot for any help on this!

This is the first notarisation activity on a newly enrolled Developer Program account. Every submission has been stuck "In Progress" with no terminal status and no log available. Oldest stuck request: UUID: bfb5a0e3-31a2-4dcd-a1c6-2f26ce6e62dd Created: 2026-05-29T13:43:22Z Team ID: ZH3S4VZT33 It has now been more than 7 days. I understand first-time submissions can be held for in-depth analysis, which is why I waited a full week before posting. Evidence this is account/team-level rather than specific to one app: A second submission the same day (e42fb5f4-8fc7-4eec-9eef-9764e756b444) and a separate throwaway probe app submitted 2026-06-01 (0333a989-3a9f-44b1-98e6-69f9ee4028e4) are all stuck "In Progress" too. xcrun notarytool log <id> returns "Submission log is not yet available" for all of them. No rejection email at the Apple ID address. Apple System Status shows Developer ID Notary Service as Available. Could someone from the notary service team check the queue for Team ID ZH3S4VZT33 and advise whether these are in the in-depth-analysis path? Happy to provide codesign output or additional UUIDs.
