Text filtering: behavior of current message is affected by behavior of past message from same origin
If there is this situation: A text message is sent from a sender and gets classified as junk (by a text filtering extension) with the result that it gets send to the spam folder as expected. A text message with different content is sent from the same sender and gets classified as allowed, however it also gets sent to the spam folder. If the above is repeated but after step 1 the message is deleted, then in step 2 the message doesn't get sent to the spam folder. So the presence of the message from step 1 being in the spam folder is having an effect on the behavior of step 2. Expected beahavour (if so, why?), or a defect?

Unable to download iOS simulator runtime 26.x on Xcode
Hi everyone, I'm experiencing a persistent issue for months now where I'm unable to download the iOS 26 simulator Runtime. I've tried reinstalling Xcode and also Xcode Beta but same issue. iOS 26 Simulator is also not on developers download page, so manual installation is impossible. And sadly I can't compile any code without having iOS 26 simulator installed. Anyone able to get passed this? Hardware: M1 Pro OS: Tahoe 26.1 Heres the error Download failed. Domain: DVTDownloadableErrorDomain Code: 41 User Info: { DVTErrorCreationDateKey = "2026-01-07 11:35:35 +0000"; } -- Download failed.

Activating a Container App from a Custom Keyboard Extension to Enable Continuous Voice Input While Preserving the Original Typing Context
Project Background: I am developing a third-party custom keyboard for iOS whose primary feature is real-time voice input. In my current design, responsibilities are split as follows: 1. The container (main) app is responsible for: Audio recording Speech recognition (ASR) 2. The keyboard extension is responsible for: Providing the keyboard UI Initiating the voice input workflow Receiving transcription results via an App Group Inserting recognized text into the active text field using textDocumentProxy.insertText(_:) Intended User Flow The intended workflow is: The user is typing in a third-party app (for example, WeChat) using my custom keyboard. The user taps a “Voice Input” button in the keyboard extension. The keyboard extension activates the container app so that audio recording and ASR can begin. After recording has started, control returns to the original app where the user was typing. The container app continues running in the background, maintaining active audio recording and ASR. Recognized text is continuously streamed back to the keyboard extension and inserted into the current cursor position in real time. Observed Industry Behavior Some popular third-party keyboards on iOS, such as WeChat Keyboard and Doubao Keyboard, appear to provide a similar user experience in which: Voice input can be initiated directly from the keyboard while typing in another app. The user remains (or returns) in the original typing context after voice input starts. Speech recognition continues and text is streamed into the active text field without interrupting the typing experience. I would like to better understand how this type of workflow aligns with iOS platform capabilities and supported APIs. My Questions Is it supported by iOS public APIs for a custom keyboard extension to activate its container app to start audio recording and ASR, then return to the original host app while the container app continues recording and performing ASR in the background? If this workflow is not supported, are there any Apple-recommended or supported alternative architectures for achieving a similar user experience, especially when audio recording and ASR logic are currently implemented in the container app rather than in the keyboard extension? Goal My goal is to design a solution that is fully compliant with iOS public APIs and platform constraints, while providing a real-time voice input experience comparable to existing third-party keyboards on the platform. Any guidance on supported APIs, recommended architectures, or relevant documentation would be greatly appreciated.

App rejection because of __SwiftValue
Hi, Our Flutter + Swift iOS app was rejected under Guideline 2.5.1 citing usage of a non-public API: Runner Classes: __SwiftValue From our analysis, __SwiftValue appears to be an internal Swift runtime type automatically generated by the Swift compiler for Swift–Objective-C bridging. It is not referenced in our source code or by any third-party frameworks and only appears in the compiled Runner binary. Has anyone encountered this rejection before? Is __SwiftValue considered a private API by App Review, or is this a known false positive? Are there any recommended build settings or mitigations to avoid this flag?

Too large clock size on iOS 26 Lock Screen.
The clock on the lock screen is too big. This is very noticeable on the serif font, the maximum size goes beyond the frame, and rests on the frame of the phone display. (Screenshot 1 & Screenshot 3) This is especially evident if you use the enlarged interface (using the Large Text function), here the time goes completely out of the frame and conflicts with the frame of the phone screen. (Screenshot 2 & Screenshot 4)

Is it technically possible to force-update ASM/MDM-distributed App Store apps via a custom update server?
Hello, I’d like to clarify the technical limitations around app updates in an Apple School Manager (ASM) + MDM environment. Environment • iOS/iPadOS devices supervised and managed via Apple School Manager • Apps are distributed via ASM (VPP / Custom App) and managed by MDM • Apps are App Store–signed (not Enterprise/In-House) • Some apps include NetworkExtension (VPN) functionality • Automatic app updates are enabled in MDM Question From a technical and platform-design perspective, is it possible to: Deploy app updates for ASM/MDM-distributed App Store apps via a separate/custom update server, and trigger updates simultaneously across all managed devices, bypassing or supplementing the App Store update mechanism? In other words: • Can an organization operate its own update server to push a new app version to all devices at once? • Or is App Store + iOS always the sole execution path for installing updated app binaries? ⸻ My current understanding (please correct if wrong) Based on Apple documentation, it seems that: 1. App Store–distributed apps cannot self-update • Apps cannot download and install new binaries or replace themselves. • All executable code must be Apple-signed and installed by the system. 2. MDM can manage distribution and enable auto-update, but: • MDM cannot reliably trigger an immediate update for App Store apps. • Actual download/install timing is decided by iOS (device locked, charging, Wi-Fi, etc.). 3. Custom update servers • May be used for policy decisions (minimum allowed version, feature blocking), • But cannot be used to distribute or install updated app binaries on iOS. 4. For ASM-managed devices: • The only supported update execution path is: App Store → iOS → Managed App Update • Any “forced update” behavior must be implemented at the app logic level, not the installation level. ⸻ What I’m trying to confirm • Is there any supported MDM command, API, or mechanism that allows: • Centralized, immediate, one-shot updates of App Store apps across all ASM-managed devices? • Or is the above limitation fundamental by design, meaning: • Organizations must rely on iOS’s periodic auto-update behavior • And enforce version compliance only via app-side logic? ⸻ Why this matters In large school deployments, delayed updates (due to device conditions or OS scheduling) can cause: • Version fragmentation • Inconsistent behavior across classrooms • Operational issues for VPN / security-related apps Understanding whether this limitation is absolute or if there is a recommended Apple-supported workaround would be extremely helpful. Thanks in advance for any clarification

Shortcuts: How to add text to a file name
Hi there, Does anyone know how to modify this Image compressor Shortcut https://www.icloud.com/shortcuts/e13d8013598f4f33830386a956a163dd so that the image it creates has the original file name + “-pressed”? Eg “Image_123” becomes “Image_123-pressed” I know of the action ‘Rename file’ but can’t make it work. The shortcut does batch processing of images if that makes any difference. Any help much appreciated:)

iOS Safari Rendering Issue: Sticky Header Sometimes Fails to Update After DOM Changes
I’m encountering an issue on iOS when rendering a list using React. Each list item uses the array index as the React key and consists of two parts: a header section that uses position: sticky for dynamic sticking behavior, and a body section whose height is automatically adjusted based on its content. When the list data is updated, I sometimes observe that the sticky header content does not update visually in time, even though the underlying data and DOM have changed. // demo.jsx import React, { useState } from 'react'; import { Button } from '@iftide/mobile'; import './style2.less'; // import data1 from './data1.json'; // import data2 from './data2.json'; const prefixCls = 'im-detaillist'; const data1 = [ { sectionTitle: '2025年05月' }, { sectionTitle: '2025年04月' }, { sectionTitle: '2025年03月' } ]; const data2 = [ { sectionTitle: '2023年08月' }, { sectionTitle: '2023年07月' }, { sectionTitle: '2023年06月' }, { sectionTitle: '2023年05月' } ]; export default function App() { const [list, setList] = useState(data1); const [toggle, setToggle] = useState(true); return ( <div> <Button title="更新2" onClick={() => { setToggle(!toggle); setList(data2); }} /> <div className={`${prefixCls}-container2`} style={{ height: `700px` }}> {list.map((section: any, sectionIdx: number) => { return ( <div className={`${prefixCls}`} key={String(sectionIdx)} // id={section.sectionTitle} > <div className={`${prefixCls}-section-title`} role="text"> {section.sectionTitle} </div> <div style={{ background: 'green', height: `${Math.ceil(400 * Math.random()) + 50}px` }} > 省略 </div> </div> ); })} </div> </div> ); } .@{prefixCls}-section-title { position: sticky; position: -webkit-sticky; will-change: transform; top: 0; z-index: 1; padding-left: 11px; width: 100%; height: 30px; font-size: var(--font-size-s); font-weight: 400; line-height: 30px; color: #000000; background-color: #F4F5F7; letter-spacing: 0; }

Send notification to Reality Composer Pro from iOS project
I am creating an Augmented Reality iOS (Not VisionOS) app using scenes created in Reality Composer Pro. I'd like my code to send a notification to a RCP scene that plays a timeline. The RCP interface has the option to set up a behaviour for this purpose: This Forum thread https://developer.apple.com/forums/thread/756978 suggests the code I need for sending a notification is: name: NSNotification.Name("RealityKit.NotificationTrigger"), object: nil, userInfo: [ "RealityKit.NotificationTrigger.Scene": scene, "RealityKit.NotificationTrigger.Identifier": "HideCharacter" ] ) but the 'scene' var needs to point to the relevant RCP scene, which is loaded within a UIViewRepresentable ARView (because even in iOS26 it seems RealityKit/RealityViews aren't quite ready for AR use) and I can't work out how to correctly access it. Examples in the link above are for working with RealityKit and VisionOS only. Code for loading the scene is as follows. How can I get the notification code above to be situated in a separate SwiftUI View and send the notification to the RCP scene? typealias UIViewType = ARView func makeUIView(context: Context) -> ARView { // Create an ARView let arView = ARView(frame: .zero) // Configure it let arConfiguration = ARWorldTrackingConfiguration() arConfiguration.planeDetection = [.horizontal] arView.session.run(arConfiguration) // Load in Reality Composer Pro scene let scene = try! Entity.load(named:"myScene)", in: realityKitContentBundle) // Create a horizontal plane anchor let anchor = AnchorEntity(.plane(.horizontal, classification: .any, minimumBounds: SIMD2<Float>(0.2, 0.2))) // Append the scene to the anchor anchor.children.append(scene) // Append the anchor to the ARView arView.scene.anchors.append(anchor) return arView } func updateUIView(_ uiView: ARView, context: Context) { } }

Misleading iOS prompt claims developers "will receive" user data
When a user enables an SMS filtering extension via iOS Settings → Messages → Text Message Filtering and selects an app, the following prompt appears: "The developer of [App Name] will receive the text, attachments and sender information in text messages from senders not in your Contacts. Messages may include personal or sensitive information like bank verification codes." This message cannot be modified by developers, and we're receiving complaints and negative reviews from users who are alarmed by it, despite our app not collecting any data. iOS should allow developers to customize this message or reword this message to not make false claims about data collection. We've opened a feedback assistant report here: FB21445903

App rejected for using non-public API __SwiftValue in Runner – Swift runtime false positive?
Hello, Our iOS app (Flutter + Swift) was rejected under Guideline 2.5.1 with the following message: The app uses or references the following non-public or deprecated APIs: Runner Classes: __SwiftValue From our investigation, __SwiftValue appears to be an internal Swift runtime class automatically generated by the Swift compiler for Swift–Objective-C bridging. It is not imported, referenced, or used directly in our source code. We verified that: The symbol exists only in the compiled Runner binary It is not referenced by any third-party framework explicitly It appears in standard Swift runtime behavior We previously removed a legitimate private API (PGHostedWindow) from a dependency and resubmitted, after which this new rejection appeared. Questions: Is __SwiftValue considered a private API usage by App Review, or is this a false positive? Are there recommended build settings or mitigations to prevent this symbol from being flagged? Should this be escalated for manual review? Any guidance from Apple engineers or developers who encountered similar rejections would be greatly appreciated. Thank you.

MultiPeer Connectivity: Device discovery succeeds but handshake fails when off-network
Hi, I am building an app that depends on multiple iOS devices connecting to a designated "coordinator" iOS device. I am using MPC, and it works great when the devices are connected to the same WiFi AP, with virtually 100% connection success. My definition of success is a near instant detection of available devices, >95% connection success rate, and a stable ongoing connection with no unexpected disconnects. The issue arises when the devices are not connected to the same WiFi network (or connected to no network with WiFi and bluetooth still on). Devices detect each other immediately, but when initiating a connection, both devices initiate a handshake, but the connection is not successful. In the few times where the connection succeeds, the connection quality is high, stable, and doesn't drop. Is this a known limitation of the framework? Could I be doing something wrong in my implementation?

There are still preview uploads in progress.
Hello everyone, I’m stuck with an App Store Connect issue and would really appreciate any insight from the community. I am unable to submit my app for review due to the following persistent error: “Unable to Add for Review – There are still preview uploads in progress.” What makes this particularly confusing is that there are no previews currently uploading. Here is everything I have already tried: Deleted all App Preview videos and all screenshots Confirmed Media Manager shows no active uploads Re-uploaded App Preview videos fully compliant with Apple specs: H.264 AAC stereo audio Constant 30 FPS Correct resolution Uploaded a new build with a higher build number (Build 3) Waited more than 24 hours after upload Logged out / logged in, refreshed, tried multiple browsers and sessions Confirmed TestFlight build upload completed successfully Despite all of this, the error persists and also prevents: Adding the app for review Creating a new app version (the “Add Version” button does not appear) Apple Developer Support has suggested submitting a higher build number, which I have done, but the issue remains. At this point, it seems like a stuck / ghost App Preview upload job on the App Store Connect backend. Has anyone experienced a similar issue? If so: How was it resolved? Did Apple need to manually clear or reset something on their side? Any advice would be greatly appreciated. Thank you in advance.

Question: How to support landscape-only on iPad app after 'Support for all orientations will soon be required' warning
Dear Apple Customer Support, I’m developing a new Swift iPadOS app and I want the app to run in landscape only (portrait disabled). In Xcode, under Target &gt; General &gt; Deployment Info &gt; Device Orientation, if I select only Landscape Left and Landscape Right, the app builds successfully, but during upload/validation I receive this message and the upload is blocked: “Update the Info.plist: Support for all orientations will soon be required.” Could you please advise what the correct/recommended way is to keep an iPad app locked to landscape only while complying with the current App Store upload requirements? Is there a specific Info.plist configuration (e.g., UISupportedInterfaceOrientations~ipad) or another setting that should be used? Thank you,

isEligibleForAgeFeatures: wrong minimum OS version
Dear Apple, while implementing Declared Age Range API in my app, I've noticed a mistake in documentation: the isEligibleForAgeFeatures property is marked 26.0+ in documentation, but 26.2+ in Xcode, which ultimately leads to inability to use it with OS below 26.2. Moreover, I'm thoroughly confused by this quote from documentation: This flag returns true on iOS and iPadOS based on a person’s eligibility and always returns false on macOS. It leads me to two questions: Is it possible to use Declared Age Range API for macOS apps? Will it be possible to use it in future? Will there be any changes regarding this matter in a meantime (especially after Jan 1st)? If yes - when should we expect these changes? If no - why this API declares macOS 26+ support alongside iOS/iPadOS, if it simply doesn't work for macOS now? As of now, my iOS app works flawlessly with given API (on iOS 26.2) while macOS app returns isEligibleForAgeFeatures = false and requestAgeRange request always throws AgeRangeService.Error.notAvailable. Also, does it mean that one should not use isEligibleForAgeFeatures boolean while implementing Declared Age Range API for apps below iOS 26.2 (I mean 26.0+)? Or implementing given API for iOS 26.2+ is a sufficient way to go? So shouldn't the whole API be marked as 26.2+? The minimum iOS version in my app is 16.0 and minimum macOS version is 13.0 anyway, so the significant part of users is left out of these updates, but the main goal here is legal compliance.

Age verification again: What does "applicable region" mean wrt isEligibleForAgeFeatures
The documentation for isEligibleForAgeFeatures states: Use this property to determine whether a person using your app is in an applicable region that requires additional age-related obligations for when you distribute apps on the App Store. But what does "region" mean? Is this going to return true if the user has downloaded the app from the US App Store? Or will it go further and geolocate the user and identify them as being within a particular relevant state within the US?
