Apple Maps Guides

Hello, Recently we got a question about the keyboard sensor data collection in our research project: For the typing statistics, was any typing included or only messaging and notes? E.g., typing in the browser, phone search, calendar, etc? While I believe it should be any typing included, I was not able to find a document explicitly stating that. Could you help to confirm it or guide me to any documentation explaining it? Thanks!

I am implementing In App Purchase and integrating App Store Server Notifications version 2. I am able to receive the JWSSignedPayload from Apple. The payload is Base64 encoded and contains header, payload, and signature. The documentation clearly explains how to decode the payload and extract claims such as notificationType and data. What is unclear is how to verify the JWS signature itself. I could not find concrete documentation that explains: Which Apple public key or certificate should be used for verification How to retrieve or rotate the key used to sign the payload The exact steps required to validate the JWS signature before trusting the payload Signature verification is critical for security, and simply decoding the claims without validation is not sufficient. I am looking for official guidance or a recommended approach to verify the JWSSignedPayload signature for App Store Server Notifications v2.

Greetings my fellow engineers, I use SwiftData in my iOS app. The schema is unversioned and consists of a single model. I've been modifying the model for almost two years now and relying on automatic database migrations. I had no problems for all that time, but now trying to add a property to the model or even remove a property from the model results in an error which seems like SwiftData is no longer capable of performing an automatic migration. The log console has things like the following: CoreData: error: NSUnderlyingError : Error Domain=NSCocoaErrorDomain Code=134190 (null) UserInfo={reason=Each property must have a unique renaming identifier} CoreData: error: reason : Can't find or automatically infer mapping model for migration CoreData: error: storeType: SQLite CoreData: error: configuration: default CoreData: annotation: options: CoreData: annotation: NSMigratePersistentStoresAutomaticallyOption : 1 CoreData: annotation: NSInferMappingModelAutomaticallyOption : 1 CoreData: annotation: NSPers

During Apple Pay in-app provisioning (EV_ECC_v2), our iOS app successfully obtains the issuer provisioning certificates and generates cryptographic material. The flow fails when Apple posts the card blob to Apple’s broker (card creation step), returning HTTP 500 from .../broker/v4/devices/{SEID}/cards. Steps: Call issuerProvisioningCertificates?encryptionVersion=EV_ECC_v2 → 200 OK; returns ECC leaf + Apple Root CA chain; nonce=2a831be4. 2. Build {encryptedCardData, activationData, ephemeralPublicKey} 3. POST /broker/v4/devices/{SEID}/cards Expected: 200 OK on /broker/v4/devices/{SEID}/cards, or 5xx with a descriptive error if payload/cryptography is invalid. Observed: 500 Internal Server Error from Apple broker on /cards (labeled “eligibility” in PassKit logs), causing a terminal failure in Wallet UI.

I am developing an Augmented Reality (AR) navigation application for the iPad, utilizing the ARCL library to place Points of Interest (POIs) in the real world. The application's behavior varies significantly based on the device's networking configuration: Cellular Network (Expected Behavior): On an iPad with a cellular modem, when using the cellular network, all POIs are placed accurately with correct orientation. Wi-Fi Only (Expected Behavior): On a Wi-Fi-only model (no GPS chip), POI placement is inaccurate, confirming the need for an external GPS receiver for that hardware configuration. Cellular + Wi-Fi (Anomalous Behavior): The iPad is a cellular model (equipped with GNSS/GPS). The device is connected to a Wi-Fi network (enforced via an MDM profile, preventing the user from disabling Wi-Fi). When actively connected to this specific Wi-Fi network, the AR POIs consistently display with an incorrect orientation and placement, even though the device hardware has a dedicated GPS chip. The placement error stro

I am developing a simple watch app and I use my personal watch for development with Xcode. Personal watch is series 10 gps only. I have two other watches that I want to use for testing the app, but not needing them to be connected to Xcode. The test watches have cellular option, and I need a cell plan per watch because the watches need to be standalone, not counting initial setup. To get the standalone cell plan the watches need to be configured using AWFK. Here is what I have tried/current issues. I switch between all three watches on my phone using the watch app. Originally tried to put test watches in developer mode, thinking I would connect to Xcode, developer mode is not available when watch is setup using AWFK. Pushed the watch app to apple connect, setup TestFlight group, added the test users and my phone user, accepted invites TestFlight is installed on my phone, I see the testflight setup for the watch app I set a test watch using watch app on the phone, run install for the test app from Tes

I'm encountering a strange behavior with one of my home's on Home app while I'm off network. When I launch the app it indicates that the hub is not responding and all of my devices are unavailable. However, on the menu bar at the bottom if I switch to Automation and back to Home the pop-up goes away and my devices are accessible again (sometimes this take a few attempts). Siri is also able to consistently control my devices without an issue. The same behavior occurs with Home app on other devices (e.g. Mac) and with other members that have access to the household. 3rd party HomeKit app like Controller does not have an issue. This issue began with iOS 26 and I haven't had much luck resolving the issue. I already tried rebooting everything, including removing and re-adding an Apple TV (home hub). I have other homes shared with me in Home App with similar network/environment that are still working. The home I'm having issues has the most number of devices though (over 100+).

Apple sent a final reminder asking developers to complete the updated age rating questions in App Store Connect. Final reminder: Answer the updated age ratings questions. We’re reaching out because you have not provided responses to the updated age ratings questions in the App Information section of your app in App Store Connect. If you don’t answer these questions by January 31, 2026, you won’t be able to submit app updates in App Store Connect. The email says that if the age rating questions are not answered by 31 January 2026, you will not be able to submit app updates. What is not clear is what actually happens after that date. Many of us are in the middle of development and may not be ready to submit a new build before the deadline. The email does not explain whether this means: A) You can still submit updates after 31 January 2026, as long as you complete the age rating questionnaire before submitting, or B) The app becomes locked and cannot be updated at all once the deadline passes This is no
