Reply to Xcode 26 fails to load SPM packages
Chiming in again with some findings. Reverting to Xcode 26.1 solved the package issue for me I'm using Tahoe 26.3.1 - I have a coworker with same project and Xcode 26.3.1, but using Tahoe 26.1 that does not have the problem. Using Is_kevin's approach using xcodebuild -resolvePackageDependencies, albeit with cleaning the package cache first worked for me on Xcode 26.3.1 too, but is cumbersome

Reply to RealityKit crashes when rendering SpriteKit scene with SKShapeNode in postProcess callback
This reminds of an error I got while setting up SKRenderer for this project: SKRenderer Demo. See code and comment in SKOfflineRenderer.swift: // If I dont use a depth/stencil texture, rendering crashes on simulator, device, and Mac // Without it, rendering only works on Xcode Live Preview let depthStencilDesc = MTLTextureDescriptor() depthStencilDesc.pixelFormat = .depth32Float_stencil8 depthStencilDesc.width = pixelWidth depthStencilDesc.height = pixelHeight depthStencilDesc.usage = .renderTarget depthStencilDesc.storageMode = .private The code is inside the init, check how the depthStencilTexture is setup for SKRenderer, it may help you.

[FB22167174] PDFKit: `buttonWidgetState = .onState` ignored for non-first radio button annotations on `dataRepresentation()`
I've run into what appears to be a bug in PDFKit's radio button serialization. When creating a radio button group with PDFAnnotation, only the first annotation added via page.addAnnotation() gets a correct /AS entry in the written PDF — all other annotations always get /AS /Off, regardless of buttonWidgetState. Minimal reproduction func makeRadioButton(optionId: String, isSelected: Bool) -> PDFAnnotation { let ann = PDFAnnotation(bounds: CGRect(x: 0, y: 0, width: 20, height: 20), forType: .widget, withProperties: nil) ann.widgetFieldType = .button ann.widgetControlType = .radioButtonControl ann.fieldName = Choice ann.buttonWidgetStateString = optionId ann.buttonWidgetState = isSelected ? .onState : .offState return ann } let pdf = PDFDocument() let page = PDFPage() pdf.insert(page, at: 0) // Intend to select B page.addAnnotation(makeRadioButton(optionId: A, isSelected: false)) page.addAnnotation(makeRadioButton(optionId: B, isSelected: true)) page.addAnnotation(makeRadioButton(optionId: C, isSelec

Reply to Active Membership but Xcode shows "Red X" at Certificates, Identifiers & Profiles
I have the same problem I've upgraded to a new Macbook recently, just when I was setting up my Xcode, I realized I there is a this red X showing up next to my development team as I was signing in to my account I have checked my permission on App Store Connect, everything seemed fine. I have also deleted my old Apple development certificate and requested for another one. Nothing worked.

Reply to Two errors in debug: com.apple.modelcatalog.catalog sync and nw_protocol_instance_set_output_handler
Based on the error messages you're encountering in Xcode, it seems like there are two main issues to address: nwprotocolinstancesetoutputhandler Not calling removeinput_handler: This error typically indicates a problem with how network connections are being managed using Apple's Network framework. Specifically, it suggests that an output handler was set on a network protocol instance without a corresponding removal of the input handler, which could lead to resource leaks or crashes. Steps to Resolve: Ensure that every call to nw_protocol_instance_set_output_handler is matched with a call to nw_protocol_instance_remove_input_handler when you're done with the connection or when the connection is closed. Review the lifecycle of your network connections to ensure handlers are properly managed, especially in asynchronous or error-prone paths. Check if there are any closures or network operations that might inadvertently leave handlers dangling. com.apple.modelcatalog.catalog sync: connection error: This e

RequestReview API does not trigger the review sheet in Xcode testing iPadOS 26.4 beta 3
Hello DTS team, the request review from StoreKit is not working in iOS 26.4 beta 3. I have filed a feedback (FB22157147). Sample code: import SwiftUI import StoreKit struct ContentView: View { @Environment(.requestReview) private var requestReview @State private var count = 0 var body: some View { VStack { Button(Increase Count) { count += 1 } Text(count, format: .number) .font(.largeTitle) } .onChange(of: count) { if count == 3 { Task { try await Task.sleep(for: .seconds(2)) requestReview() print(Request Review triggered!) // On iPadOS 26.4 beta 2 & 3, requestReview() does not trigger any review system sheet when testing in Xcode 26.3 // Works on iOS 26.3.1 } } } } }

Reply to Swiftui Map Leagal Text is transformed when rotationEffect is applied to Map
Hi, To provide some context on how this view fits into the overall layout: the map is displayed inside an info box that can be swiped away. When no swipe gesture is in progress, the map should remain interactive and allow zoom gestures. While the info box is being swiped, interaction with the map should be disabled. The map always displays at least one marker. You can find a more complete code example and a screenshot here: import MapKit struct ContentView: View { @State private var offset = CGSize.zero let position = CLLocationCoordinate2D(latitude: 51.5074, longitude: -0.1278) let span = MKCoordinateSpan(latitudeDelta: 5.0, longitudeDelta: 5.0) var body: some View { ZStack { let drag = DragGesture() .onChanged { g in offset.width = g.translation.width offset.height = g.translation.height } .onEnded{ _ in withAnimation { offset = .zero } } VStack(spacing: 0){ Map(initialPosition: .region(MKCoordinateRegion(center: position, span: span)), interactionModes: [.zoom]){ Marker(London, coordinate: positio

Reply to Xcode 26.3 RC - Claude Agent returns "Your request couldn't be completed"
The Prompt stream failed: Agent has been closed error can occur when your project is in a macOS privacy-protected directory like ~/Desktop, ~/Documents, or ~/Downloads. macOS should prompt you to grant Claude access to these locations, but if the prompt doesn't appear or was previously denied, the agent can fail with this error. Workaround: Move your project to a non-protected directory such as ~/src, then reopen it in Xcode.

Reply to Questions about VoIP Push compliance rules and CallKit handling
We do not use CallKit. The call is handled entirely using a custom in-app call UI. This is a bad idea. It's going to significantly complicate your app’s audio logic and, most practically, it means that ANY other incoming call from ANY CallKit app will IMMEDIATELY interrupt your app’s audio. It's also going to allow a variety of other odd edge cases which will be similarly disruptive (for example, now playing activity can interrupt your calls). The PRIMARY reason CallKit was originally created was so the system could properly arbitrate and manage the audio of VoIP apps, preventing all those edge cases. However, the exact rules and thresholds for these violations are not clearly documented, so I’d like to ask a few questions to better understand the expected behavior. The basic policy rule is that your app is not required to report a call if it either: Is already on a call. Is in the foreground. However, in practice, both of those criteria are much harder to implement than they seem. The problem here is that yo

Xcode 26.4 Beta 2 - Missing Capability, Family Controls App & Website Usage
Hi One of the new Family Control API's requires the new Family Controls App & Website Usage capability but it appears to be missing in the latest Xcode beta (26.4 B2). MacOS and iOS all running 26.4 Beta 3. Does anyone know if we have to wait for Xcode 26.4 Beta 3 and it's associated SDK's for this one to become available?

Reply to Confirmation Items Regarding the Mandatory UIScene Lifecycle Support in iOS 27
Thank you for your post. If I’m not mistaken this means that at the time when Xcode 27 becomes mandatory, the app’s deployment target must be iOS 13 or higher since the UIScene class and Info.plist keys are iOS 13.
