Overview

I have a single multiplatform application that I use NSPersistentCloudKitContainer on. This works great, except I noticed when I open two instances of the same process (not windows) on the same computer, which share the same store, data duplication and "Metadata Inconsistency" errors start appearing. This answer (https://stackoverflow.com/a/67243833) says this is not supported with NSPersistentCloudKitContainer. Is this indeed true? If it isn't allowed, is the only solution to disable multiple instances of the process via a lock file? I was thinking one could somehow coordinate a single "leader" process that syncs to the cloud, with the others using NSPersistentContainer, but this would be complicated when the "leader" process terminates. Currently, it seems iPad split views are new windows, not processes -- but overall I'm still curious :0 Thank you!

Hi, I am running build on ios 26.2 device, connected with cable (not wifi) and it crashes because files are not loaded or something. But when i turn off Debug Exetuble, it works just fine. Also, tried to run on ios 18.2 device, with Debug executable On - everything is ok, and breakpoints work. My guess, App crashes on reading and loading Assets and others app files like certificates. XCode run logs shows: **"Too many file errors". ** sample.txt xcode_run_logs.txt Also, exectued image list on lldb console, could not attach here, if needed i can add it with some url here.

Hello, We are developing an iAP2 accessory and encountering an issue during the Identification phase. Issue: Authentication: ✅ Successful Identification: ❌ IdentificationInformation rejected (0x1D03) Product Plan Status: "Submitted" (in MFi Portal) What we've verified: ProductPlanUID matches MFi Portal All required parameters per R43 Table 101-9 are included Parameters are in ascending order by ID Message format appears correct Observation: iPhone accepts the message format but still rejects IdentificationInformation, suggesting the issue may be related to Product Plan configuration or status rather than parameter format. Questions: Can a Product Plan with status "Submitted" complete iAP2 identification, or does it need to be "Approved"? Are there any Product Plan configuration requirements that might not be visible in MFi Portal? Should we configure "Control Message Lists" in Product Plan? (We don't see this option in Portal) We can provide additional technical details through secure channels if needed. Thank you for your assistance.

Hello everyone, I’m experiencing a visual issue when dismissing a sheet on iOS 26. I’m using the same implementation shown in the official Apple documentation. While testing, I noticed that some apps do not exhibit this behavior. However, when running this code on iOS 26, the issue consistently occurs. Issue description: The sheet dismisses abruptly A white screen briefly appears for a few milliseconds and then disappears This results in a noticeable visual glitch and a poor user experience I tested the exact same code on iOS 18, where the sheet dismisses smoothly and behaves as expected, without any visual artifacts. Has anyone else encountered this issue on iOS 26? Is this a known bug, or is there a recommended workaround? Any insights would be greatly appreciated. Thank you.

My iOS app uses CloudKit key-value storage. I have not updated the app in a few years but it works fine. Since it was last updated, I transferred the app from an old organization to my personal developer account. Now that I'm working on the app again I get an error: Provisioning profile "iOS Team Provisioning Profile: com.company.app" doesn't match the entitlements file's value for the com.apple.developer.ubiquity-kvstore-identifier entitlement. In the entitlement file, it has $(TeamIdentifierPrefix)$(CFBundleIdentifier) as the value for iCloud Key-Value Store. I've verified the variables resolve as expected. When I parse the provisioning profile there is no entitlement value for key-value storage. What am I getting wrong?

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; }

I’m writing to report a serious usability regression in the iOS 26 Photos app. Folders can still be created and albums can still be assigned to them, but folders can no longer be opened to view the albums they contain. A container that cannot be opened is not a container, and this breaks a fundamental information architecture model that has existed in Photos for well over a decade. This change disproportionately harms users who maintain large, intentional photo libraries—travel archives, projects, professional work, or long-term personal documentation—where hierarchy and ordering are essential. Search and automated surfacing are not substitutes for deliberate structure. Removing the ability to browse folder → album hierarchy on iOS strips users of control while still exposing the UI for folder creation, which is internally inconsistent. If this behavior is intentional, it should be clearly documented and the folder UI removed to avoid misleading users. If it is not intentional, it needs urgent correction. At minimum, iOS should retain parity with macOS Photos for basic navigation of folders and albums. This is not a niche request; it is a regression in core functionality.

Hi, I'm using LanguageModelSession and giving it two different tools to query data from a local database. I'm wondering how I can have the session generate structured content as the response that includes data one or both tools (or no tool at all). Here is an example of what I'm trying to do: Let's say the app has access to a database that contains information about exercise and sleep data (this is just an analogy). There are two tools, GetExerciseData() and GetSleepData(). The user may then prompt something like, "how well did I sleep in November". I have this working so that it calls through to the right tool, which would return a SleepSummary. However, I can't figure out how to have the session return the right structured data. I can do this and get back good text data: let response = session.respond(to: userInput), but I believe I want to do something like: let response = session.respond(to: trimmed, generating: <SomeStructure?>) Sometimes the model I run one tool or the other, or both tools, or no tool at all. Any help of what the right way to go about this would be much appreciated. Most of the example I found have to do with 1 tool.

I changed the AppIcon in Images.xcassets,and distribute a new version on appstore;The icon have changed on the desktop, but elsewhere, such as when switching between apps, the top left corner shows the old version of the icon.When I restart my phone,the top left corner show the new version of the icon;My phone is iPhone 13 Pro Max,iOS 18.4.1;Is there other ways to resolve the problem without restart the phone?

I have a SwiftUI-based universal app which creates a file that it stores in documentsDirectory. On iOS/iPadOS, this file is stored in the application's Documents directory and is accessible via the Files app. On MacCatalyst, this operation does the same thing — it creates the file and stores it in ~/Library/Containers/<app directory>/Data/Documents. However what I want is for the document to be stored in ~/Documents, so that it is easily accessible to the user. How can I do that? I'd like it to occur without (for example) having to show a SaveFile panel...

Please kindly improve the Safari browser side bar implementation further along with what The Browser Company has done with their Arc browser. Arc is about to retire soon too and they're willing to sell their SwiftUI code perhaps too for a decent pile of dollars, not the Jony Ive piles at least it should not. The toggle for side bar is nice and works perfect though!

I've been playing around with iPad PRO M5 13" as part of my goal to implement some music relating SPH particle simulation effects on it - and this involves utilizing tap events also from the incredible looking fresh screen the device has. See more information from here, all should be overreactively implemented but the ideas remain (with almost zero cost copy fragment shader) : `https://youtu.be/ci-GSgQ0wlM` This attached image shows the tap effects implementation brought just bit a little further than in the video.

My project requires the on-device apple intelligence models (FoundationModels) which are only available for iPad on iPad Pro M1 and later, iPad Air M1 and later, iPad mini A17 Pro. If they don't judge on one of these devices, my project might not work properly as FoundationModels is a pretty big part of my project. For this reason I really need to know what devices the Swift Student Challenge will be judged on.

I've been playing around with the recently published iPad PRO M5 13" and it's awesome in most ways I've been able to think of. But this video capture of the app I'm developing, for example, lacks it the app icon "should" be just slightly translucent as I see it. https://youtube.com/CAukICBrVzw However I'm not and UI/X person and this is primarily my personal preference only for an option to allow for devs.

Is there any way for an iOS app to get a log of all Airdrop transfers originating in all apps on the iOS device e.g. from the last week?

Hello, I hope you are doing well. I recently submitted my app for review, and it was rejected. However, I am still unsure about the exact reason for this decision. I carefully reviewed the feedback provided, but some points remain unclear to me. Could you please clarify which specific guidelines were not met, or which parts of the app need to be changed or improved? My goal is to fully understand the issue so I can fix it properly and ensure that the app complies with all App Store Review Guidelines in the future. Thank you in advance for your time and support.

I want to help contribute a feature in a virtual-machine app in macOS that supports PCIe device passthrough over thunderbolt. I have a question about the entitlements. Since I do not represent the GPU vendors, would I be allowed to get a driver signed that matches GPU vendor IDs? Is there such a thing as wildcard entitlement for PCIDriverKit? I don't want end-users to have to disable SIP to be able to use this. Any suggestions/leads? Thank you.

Hello guys, recently I integrated a third-party library into my code to handle blur effects (Glur). This library leverages Metal's compute capabilities and appears to automatically depend on the Metal toolchain during the build process. When using Xcode Cloud, the archive step consistently fails with a "CompileMetalFile Failed" error. However, when I manually archive the project in Xcode locally, everything works fine without any issues. I’ve confirmed that the macOS and Xcode versions specified in my Xcode Cloud workflow are correct. Reply if you know how to fix it or it will be fixed future, thanks. I'm using Xcode 26.2(17C52) and macOS(15.7.1 (24G231))
