I just updated to Tahoe 26 and Xcode 26, and now a SwiftUI project that was working just fine, simply shows a blank canvas. I closed Xcode and reopened, but get the same results. Note that there is no error message and the project builds and displays normally. Steps to blank canvas: Open Xcode I see Canvas Paused Click on the circle The Form opens with a blank screen Build the project The Form opens with all controls showing Jim

I'm developing a watchOS companion app for my iOS app in Xcode 26.0.1 on macOS Sequoia. The watch app uses a simple ObservableObject class with @Published properties for state management, which compiles fine for iOS but fails for the watchOS target. Error: Initializer 'init(wrappedValue:)' is not available due to missing import of defining module 'Combine' Code: swiftimport SwiftUI import WatchConnectivity import Combine // Added explicitly class WatchConnectivityProvider: NSObject, ObservableObject { @Published var distance: Double = 0 @Published var isActive: Bool = false // Additional @Published properties... } Environment: Xcode 26.0.1 (17A400) macOS Sequoia watchOS deployment target: 11.0 Apple Watch Series 11 running watchOS 11.6.1 What I've tried: Adding import Combine explicitly Cleaning build folder Verifying target membership This same code pattern works in the iOS target Is @Published / Combine supported differently in watchOS under Xcode 26? This code worked in previous Xcode versions. Wh

I am currently struggling with resolving what appear to be competing design issues, and (while I may be just demonstrating my own ignorance) I would like to share my thoughts in the hope that you may have useful insights. For purposes of discussion, consider a large and complex data entry screen with multiple sections for input. For all of the usual reasons (such as reuse, performance management, etc) each of these sections is implemented as its own, separately-compiled View. The screen is, then, composed of a sequence of reusable components. However, each of these components has internal structure and may contain multiple focusable elements (and internal use of .onKeyPress(.tab) {...} to navigate internally). And the logic of each component is such that it has an internal @FocusState variable defined with its own unique type. So, obviously what I want is on the one hand, to provide a tab-based navigation scheme for the screen as a whole, where focus moves smoothly from one component's internals to the next c

I have a SwiftUI Mac Catalyst app that shows a video player using a UIViewControllerRepresentable AVPlayerViewController. When I tap the full screen button on the native playback control, the app crashes. The app crashes only when built with Xcode 26. When I build with Xcode 16, this does not cause a crash. Here is some of the crash log: 0 CoreFoundation 0x000000019a5cc770 __exceptionPreprocess + 176 1 libobjc.A.dylib 0x000000019a0aa418 objc_exception_throw + 88 2 CoreFoundation 0x000000019a69b7fc -[NSException initWithCoder:] + 0 3 AppKit 0x000000019eeee1d0 -[NSBezierPath(NSBezierPathDevicePrimitives) _deviceMoveToPoint:] + 104 4 AppKit 0x000000019eeec930 -[NSBezierPath appendBezierPathWithRoundedRect:xRadius:yRadius:] + 200 5 AppKit 0x000000019eeea238 +[NSBezierPath bezierPathWithRoundedRect:xRadius:yRadius:] + 88 6 AVKitMacHelper 0x0000000247d73cc4 -[AVScrubberSliderCell drawBarInside:flipped:] + 1264 7 AppKit 0x000000019f35cf7c -[NSSliderCell drawInteriorWithFrame:inView:] + 680 8 AppKit 0x000000

Hello everyone, I am migrating a legacy KEXT to a DriverKit (DEXT) architecture. While the DEXT itself is working correctly, I am completely blocked by a code signing issue when trying to establish the UserClient connection from our SwiftUI management app. Project Goal & Status: Our DEXT (com.accusys.Acxxx.driver) activates successfully (systemextensionsctl list confirms [activated enabled]). The core functionality is working (diskutil list shows the corresponding disk device node). The Core Problem: The userclient-access Signing Error To allow the app to connect to the DEXT, the com.apple.developer.driverkit.userclient-access entitlement is required in the app's .entitlements file. However, as soon as this entitlement is added, the build fails. Both automatic and manual signing fail with the same error: `Provisioning profile ... doesn't match the entitlements file's value for the ... userclient-access entitlement.` This build failure prevents the generation of an .app bundle, making it impossibl

When I migrate to swift6.2, the photopicker always giving the warning like below: Call to main actor-isolated initializer 'xxxfunction' in a synchronous nonisolated context it's so weird，because no matter it's a viewbuilder or a struct view，it can't fix the warning.

I made a custom SwiftUI control with two sliders trying to mimic the appearance of the new sliders in version 26 OSs. I was able to get something close to the way Apple's single slider looks and works. This is how it normally looks: And this is how it looks when one of the sliders is being dragged: This isn't perfect but I could live with it. Except that I want to use that control in a SwiftUI List, and by placing it in the list it doesn't have the same appearance though it functions the same. When the thumbs aren't being dragged it looks like this: Same as before which is great. But when one of the thumbs is being dragged it looks like this: Something about dropping the control into a List broke the transparency effect. All these screenshots were taken using the Xcode simulator for iOS. I achieved the transparency effect using .glassEffect(.clear.interactive(true)) on the thumb, along with a second capsule drawn on top when the thumb isn't being dragged. I needed the second capsule, if I me

Hi, I’m running into a persistent error while implementing StoreKit 2 renewable subscriptions in my SwiftUI app. Context I have a two-screen flow: Screen 1: user selects a subscription plan (monthly / yearly). Screen 2: user fills out personal information and taps Subscribe that triggers the purchase function. On first launch or the first couple of purchases (on both Storekit's local and Sandbox testing), everything works fine. The App Store popup appears, the purchase goes through, and I get the transaction result. But after a few runs (3rd or 4th purchase attempt onward), my app crashes the moment the App Store purchase popup appears. Error Logs When the crash happens, the console shows: `unable to close due to unfinalized statements or unfinished backups BUG IN CLIENT OF libsqlite3.dylib: database integrity compromised by API violation: vnode unlinked while in use: /private/var/mobile/Containers/Data/Application/D8D97A11-DF06-4EF2-AC55-138C4739A167/Library/d6d2e85a60f0480c4c17834eeb827a14_MPDB.sql
