Issue After upgrading to Tahoe 26.2, print queues monitored by PaperCut no longer work. The print queue gets paused, and the jobs fail to print. This issue was discovered during our internal testing prior to the Tahoe 26.2 public release, and a growing number of our mutual customers have also reported it since then. Root cause This appears to be due to changes in the behavior of CUPS Sandbox restrictions, which prevent the backend (and filter) from reading/writing to the PaperCut install folder.

Hi everyone, In the simple app below, I have a QueryView that has LazyVStack containing 100k TextField's that edit the item's content. The items are fetched with a @Query. On launch, the app will generate 100k items. Once created, when I press any of the TextField's , a severe hang happens, and every time I type a single character, it will cause another hang over and over again. I looked at it in Instruments and it shows that the main thread is busy during the duration of the hang (2.31 seconds) updating QueryView. From the cause and effect graph, the update is caused by @Observable QueryController .(Bool). Why does it take too long to recalculate the view, given that it's in a LazyVStack? (In other words, why is the hang duration directly proportional to the number of items?) How to fix the performance of this app? I thought adding LazyVStack was all I need to handle the large dataset, but maybe I need to add a custom pagination with .fetchLimit on top of that? (I understand that ModelActor would be

Hi everyone, I'm having a frustrating issue with in-app purchases on 2 of my apps, and despite following all the steps correctly, they're getting rejected during App Store review because the products screen doesn't load for reviewers. I could really use some help figuring out what I'm missing. What I've Done (Following Apple's Documentation) Created products in App Store Connect: Added each in-app purchase individually with correct Product IDs These IDs match exactly the ones in my .storekit file Filled out all required information: translations, pricing, descriptions Everything was filled correctly Submitted products for review: Each product went through the separate review process All products were approved individually Linked the approved products to my app build App submission: Uploaded new build with in-app purchases implemented Products are properly configured in the app code Used StoreKit for testing (products load correctly in sandbox) The Problem Even after all products are approved and linked to the

When using UITraitBridgedEnvironmentKey to pass a trait value to the swift environment, it causes a crash when trying to access the value from the environment. The issue seems to be related to how swift uses the UITraitBridgedEnvironmentKey protocol since the crash occurs in swift::_getWitnessTable () from lazy protocol witness table accessor…. It can occur when calling any function that is generic using the UITraitBridgedEnvironmentKey type. I originally encountered the issue when trying to use a UITraitBridgedEnvironmentKey in SwiftUI, but have been able to reproduce the issue with any function with a similar signature. https://developer.apple.com/documentation/swiftui/environmentvalues/subscript(_:)-9zku Steps to Reproduce Requirements for the issue to occur Project with a minimum iOS version of iOS 16 Build the project with Xcode 26 Run on iOS 18 Add the following code to a project and call foo(key: MyCustomTraitKey.self) from anywhere. @available(iOS 17.0, *) func foo(key: K.Type) where K: UITra

Dear Apple, please make sure this bug gets delivered to whoever is responsible. That's all I ask. Please don't let it sit for months unassigned. This is, by far, the worst bug I've ever found with the macOS wallpaper system. FB21532401 If you own a 13 2020 or newer MacBook pro model, set to the default resolution, and are running macOS Tahoe, macOS will significantly degrade the quality of any image set as wallpaper. When a still image is set as the wallpaper on macOS Tahoe, on some display configurations, the systems downscales the image to an incorrect size, resulting in pixelated wallpaper. The problem is exacerbated by the fact that macOS Wallpaper Agent appears to be using a less than ideal downscaling algorithm, which results in Super Mario Bros’ type pixelation (nearest neighbor) as opposed to any other reasonable modern method (like bicubic.) The issue does not repro on macOS Sequoia. Every model MacBook we’ve tested offers some resolutions with some form of this problem, but the 13” is the o
