Hello Apple Team, We’re building a CloudKit-enabled Core Data app and would like clarification on the behavior and performance characteristics of Binary Data attributes with “Allows External Storage” enabled when used with NSPersistentCloudKitContainer. Initially, we tried storing image files manually on disk and only saving the metadata (file URLs, dimensions, etc.) in Core Data. While this approach reduced the size of the Core Data store, it introduced instability after app updates and broke sync between devices. We would prefer to use the official Apple-recommended method and have Core Data manage image storage and CloudKit syncing natively. Specifically, we’d appreciate guidance on the following: When a Binary Data attribute is marked as “Allows External Storage”, large image files are stored as separate files on device rather than inline in the SQLite store. How effective is this mechanism in keeping the Core Data store size small on device? Are there any recommended size thresholds or known limits for h

Hi, Is it possible for a macOS (or iOS/ipadOS) app to communicate with a CCID-compliant reader using the CCID interface (i.e., directly sending the PC_TO_RDR_* messages) instead of using the CryptoTokenKit API? Apple's CCID driver (/System/Library/CryptoTokenKit/usbsmartcardreaderd.slotd) seems to support all the PC_TO_RDR and RDR_TO_PC messages: https://blog.apdu.fr/posts/2023/11/apple-own-ccid-driver-in-sonoma/#enable-my-ccid-driver The background for this question is that we develop smartcard products and we'd like to use the finer grained settings provided by the CCID specification for testing/demo purposes. Thank you.

hello i am new to apple ecosystem and development i have some coding experience with c# now i like to develop my game for iphone 16 and up(due to ability to run ai models) but i am having hard time figuring out what to use there is a lot of resources for scene-kit but on its doc page it says its deprecated so i look at the reality-kit docs and tutorials and its strictly tells how to develop for visionos and i am really confused about this since there is no tutorials that shows how to develop a game for ios with reality-kit that does not focus visionos. i just want to develop for iphone 16 and up but i cant find resources focuses at that.

I watched this year WWDC25 Read Documents using the Vision framework. At the end of video there is mention of new DetectHandPoseRequest model for hand pose detection in Vision API. I looked Apple documentation and I don't see new revision. Moreover probably typo in video because there is only DetectHumanPoseRequst (swift based) and VNDetectHumanHandPoseRequest (obj-c based) (notice lack of Human prefix in WWDC video) First one have revision only added in iOS 18+: https://developer.apple.com/documentation/vision/detecthumanhandposerequest/revision-swift.enum/revision1 Second one have revision only added in iOS14+: https://developer.apple.com/documentation/vision/vndetecthumanhandposerequestrevision1 I don't see any new revision targeting iOS26+

Hi, My app uses the NetworkExtension framework to connect to an access point. For some reason, my app occasionally fails to find and/or connect to my AP (which I know is online and beaconing on a given frequency). This roughly happens 1/10 times. I am using an iPhone 17, running iOS 26.0.1. I am connecting to a WPA2-Personal network. In the iPhone system logs, I see the following: Oct 10 10:34:10 wifid(WiFiPolicy)[54] : Dequeuing command type: Scan pending commands: 0 Oct 10 10:34:10 wifid(WiFiPolicy)[54] : __WiFiDeviceCopyPreparedScanResults: network records count: 0 Oct 10 10:34:10 kernel()[0] : wlan0:com.apple.p2p: WiFi infra associated, NAN DISABLED, , DFS state Off, IR INACTIVE, llwLink ACTIVE, RTM-DP 0, allowing scans Oct 10 10:34:10 kernel()[0] : wlan0:com.apple.p2p: isScanDisallowedByAwdl[1148] : InfraScanAllowed 1 (RTModeScan 0 NonSteering 0 assistDisc 0 HTMode 0 RTModeNeeded 0 Immin 0 ScanType 1 Flags 0 ScanOn2GOnly 0 DevAllows2G 1) Oct 10 10:34:10 kernel()[0] : wlan0:com.apple.p2p: IO80211

Hi everyone, I recently acquired an app through an acquisition transaction. The process involved sending funds to an escrow service, ... unfortunately, the day I did that, the seller received an app transfer filter (apparently due to a spike in refund requests). As a result, I now own the codebase and Android version of the app, but I do not have access to the iOS version under the original developer account. My Questions: 1. Feasibility: Is it possible to take down or disable the existing iOS app (which has active subscribers) and republish it under my own Apple Developer account? If so, what are the steps and potential pitfalls? 2. Subscriptions: How would this transition affect active subscribers? Can I migrate them to a new app, or would they need to resubscribe? 3. Best Practices: Is this approach advisable, or are there better ways to handle this situation (e.g., negotiating with the seller, contacting Apple Support, etc.)? Additional Context: I have full access to the codebase and bac

Hi everyone, I’ve been exploring the process of building a food delivery app for iOS — something similar in concept to Uber Eats or DoorDash — and I wanted to get insights from this community on how to make it scalable, efficient, and user-friendly from a technical standpoint. I recently went through a really detailed guide on Food Delivery App Development that covers architecture, features, and cost estimation. It got me thinking about a few Apple-specific development challenges and opportunities: Optimizing real-time order tracking using MapKit + Core Location — how are developers here handling live driver updates efficiently without draining battery or hitting API rate limits? Push notifications & dynamic updates — what’s the best way to design these using Apple Push Notification service (APNs) to ensure timely delivery and minimal latency? Data synchronization across user roles (customer, restaurant, driver) — would CloudKit be a viable option for lightweight sync, or should we rely on a cust
