Hello Apple Developer Technical Support Team, I’m working on an iOS banking/security SDK and we’re trying to match an Android feature that reads payment cards via NFC (EMV). On Android, this is implemented using an NFC scanning screen (e.g., “NfcScanActivity”) that can read EMV data from contactless credit/debit cards. Could you please clarify the current iOS capabilities and App Store policy around this? On iOS, is it currently possible for a third-party App Store app to read contactless credit/debit cards using Core NFC (i.e., accessing EMV application data/AIDs from payment cards)? If this is possible, what are the supported APIs/frameworks and any entitlement requirements (if applicable)? If this is not possible for App Store apps, could you recommend the closest acceptable alternatives for achieving a similar user outcome? For example: Using Apple Pay / PassKit flows for payment-related experiences Card scanning alternatives (camera-based OCR) for capturing card details (if allowed) Using an external cer

Hi, I’m looking for clarification on what concurrency and consistency guarantees Apple provides when multiple targets (main app + Widget extensions) access shared storage. Specifically: 1. UserDefaults (App Group / suiteName:) • If multiple processes (app + multiple widget instances) read and write the same shared UserDefaults, what guarantees are provided? • Is access serialized internally to prevent corruption? • Are read–modify–write operations safe across processes, or can lost updates occur? 2. Core Data (shared SQLite store in App Group container) • Is it officially supported for multiple processes to open and write to the same Core Data SQLite store? • Are there recommended configurations (e.g. WAL mode) for safe multi-process access? • Is Apple’s recommendation to have a single writer process? 3. FileManager (shared container files) • If two processes write to the same file in an App Group container, what guarantees are provided by the system? • Is atomic replaceItemAt the r

Hi, I’m trying to better understand how AVAssetDownloadConfiguration selects video variants when downloading HLS content for offline playback. Suppose I have an HLS master playlist (.m3u8) that contains several video variants defined with #EXT-X-STREAM-INF. For example, the master playlist may contain multiple video streams like this: Same resolution, different BANDWIDTH Or different resolutions (for example 720p, 1080p, etc.) My question is: How many video variants are actually downloaded when using AVAssetDownloadConfiguration without specifying any variantQualifiers? In other words: If the master playlist contains multiple video variants, will the download task fetch only one variant, or multiple variants? Does the behavior differ depending on whether the variants differ only by BANDWIDTH or also by RESOLUTION? What I observed in testing In my tests, I always end up with only one video variant downloaded, specifically the one with the highest BANDWIDTH parameter. In the m3u8 files I tested, all video varia

I'm building an app that uses the Family Controls / Screen Time APIs (FamilyControls, ManagedSettings). My app has three targets, each with a distinct Bundle ID: Main App Shield Configuration Extension ShieldAction Extension All three have com.apple.developer.family-controls in their entitlements files, and they share an App Group. My question is about the distribution entitlement request form at developer.apple.com/contact/request/family-controls-distribution: does the form need to be submitted once per Bundle ID, or is a single submission for the main app sufficient to then enable Family Controls (Distribution) for the extension Bundle IDs in the developer portal as well? I've seen conflicting reports in other forum threads — some developers say one submission covers all targets, others say separate submissions are needed per Bundle ID. I've already submitted the main app, but now I am wondering whether I should submit one for each Shield extension. Thanks!

Of all the reasons I thought I might be rejected, I never thought this might be a possibility! The usefulness of the app is limited by the minimal functionality it currently provides. My app lets you track where you are in TV shows - you can add a show, tag shows (which appear as tabs), expand a show's seasons, mark an episode as watched, tap an episode to view its summary, and (if you have It installed) open the episode in Callsheet. You can also get a notification when a new season of a show drops. **Does anyone have experience with dealing with this kind of rejection? ** I'm wondering if they are dealing with an onslaught of vibe coded apps and are being more liberal with this rejection (this is not vibe coded!). The whole point of this app is that I didn't want a cluttered app with recommendations and other nonsense - I specifically wanted a simple, clean UI. https://tvnext.app Thanks, Damian App Id: 6757971087

Have a peculiar problem I'm not able to solve. Working on an app with a mapview in the max zoomed out globe level. For some reason this morning Xcode froze/crashed when I was working and I had to force quit to get it back up. Then a new issue of graphical artifacts on the space section of the Mapview showed up. This Tuesday has now been spent in full on trying to solve this to no avail. I created a new project for iOS/iPadOS and added a similar map implementation. It works fine. I used Claude to help me after a few reinstalls of Xcode with this. I asked claude to summarize - this is what has been done: Claude generative AI summary starts here---------- Here's a complete summary of everything attempted: The Problem SwiftUI tvOS app with MapKit globe view showing severe rendering artifacts — corrupted pixels surrounding the globe. Started after Xcode crashed while the tvOS simulator was actively running. iOS simulator, macOS Maps app, and all native apps work perfectly. Only tvOS simulator Map

Hi, I am submitting auto-renewable subscriptions for the first time for a brand new iOS app (never approved before). Setup: App ID has In-App Purchase capability enabled Subscriptions created under a subscription group All metadata (pricing, localization, availability) completed Subscriptions currently show In Review Testing via TestFlight build Bundle ID matches App Store Connect Using react-native-iap (StoreKit under the hood) When calling: await getSubscriptions({ skus }) I consistently get: products fetched: 0 ProductsUnavailableError Also, the app version page does not show the “In-App Purchases and Subscriptions” section. Question: For a brand new app, will StoreKit return empty products while the first subscriptions are in review? Do the first subscriptions need to be approved and/or attached to a new app version before they become available in TestFlight sandbox? Thanks for any clarification.

I can see the user’s real daily Screen Time perfectly inside a DeviceActivityReport extension on a physical device. It’s right there. But the moment I try to use that exact total inside my main app (for today’s log and a leaderboard), it dosnt work. I’ve tried, App Groups, Shared UserDefaults, Writing to a shared container file, CFPreferences Nothing makes it across. The report displays fine, but the containing app never receives the total. If this is sandboxed by design, I’d love confirmation. Thanks a lot

Context: I am building an iOS productivity app using EAS Build. The project has 4 targets: the main app and 3 extensions (ShieldAction, ShieldConfiguration, ActivityMonitorExtension). The Issue: I have officially received approval from Apple for the Family Controls (Distribution) entitlement for my main Bundle ID. However, the build still fails during the Xcode phase. The Errors: Xcode reports that the generated provisioning profiles do not include the com.apple.developer.family-controls entitlement. For example: Provisioning profile *[expo] com.*.** AdHoc 177247892.... doesn't support the Family Controls capability. All 3 extensions are failing with the exact same error. What I've done: Confirmed approval from Apple for com.*.**. Enabled Family Controls and App Groups on the Apple Developer Portal for all 4 Identifiers. Cleared EAS local and remote cache using eas build --clear-cache. Deleted existing profiles on both Expo.dev and Apple Portal to force regeneration. The Question: Even with official
