“missing package product”

I'm currently reviewing the various DCError cases defined in Apple’s DeviceCheck framework (reference: https://developer.apple.com/documentation/devicecheck/dcerror-swift.struct). To better understand how to handle these in production, I’m looking for a clear breakdown of: Which specific DCError values can occur during service.generateKey, service.attestKey, and service.generateAssertion The realworld scenarios or conditions that typically cause each error for each method. If anyone has insight on how these errors arise and what conditions trigger them, I’d appreciate your input.

This is my first time submitting an app to the App Store. I uploaded a build through Xcode a few days ago, but no build is visible in my app record on App Store Connect (nor are any builds listed in the TestFlight tab). I haven't submitted the app for review yet, because I assumed it needs a build attached first. Did I miss a step in uploading the build?

Hi, I want to create a ControlWidget button that acts as a shortcut in the control center open a specific view within my app to show a badge. Problem: I can‘t get it to open my host app. I tried a custom myapp:// protocol - did not work, I tied AppIntent with the openAppWhenRun set to true - did not work and the strange thing is the debugger breakpoint in perform will only get triggered if this is set to false. OpenIntent did not work either even if I use a dummy swift app as host to try it out. What is the current supported way (iOS 18 and 26) to open your app when a static ControlWidget button is clicked, what could I have done wrong / am missing?

I've been hitting a weird SwiftUI bug with navigation and state loss and I've managed to reproduce in a very tiny sample project. I've submitted a Feedback FB21681608 but thought it was worth posting here incase any SwiftUI experts can see something obviously wrong. The bug With deeper levels of navigation hierarchy SwiftUI will dismiss views when backgrounding the app. Any work around would be appreciated. This happens in a real app where we have to navigate to a settings screen modally and then a complex flow with other sheets. Sample code Happens in the simulator and on device. import SwiftUI struct ContentView: View { @State private var isPresented = false var body: some View { Button(Show first sheet) { isPresented = true } .sheet(isPresented: $isPresented) { SheetView(count: 1) } } } struct SheetView: View { private enum Path: Hashable { case somePath } @State private var isPresented = false var count: Int var body: some View { NavigationStack { VStack { Text(Sheet (count)) .font(.largeTitle) /

Summary Since macOS 26, our Core ML / MPS inference pipeline produces incorrect results on Mac mini M1 (Macmini9,1, A14-class SoC). The same model and code runs correctly on M2 and newer (A15-class and up). The regression appears to be in the Scaled Dot-Product Attention (SDPA) kernel path in the MPS backend. Environment Affected Mac mini M1 — Macmini9,1 (A14-class) Not affected M2 and newer (A15-class and up) Last known good macOS Sequoia First broken macOS 26 (Tahoe) ? Confirmed broken on macOS 26.3.1 Framework Core ML + MPS backend Language C++ (via CoreML C++ API) Description We ship an audio processing application (VoiceAssist by NoiseWorks) that runs a deep learning model (based on Demucs architecture) via Core ML with the MPS compute unit. On macOS Sequoia this works correctly on all Apple Silicon Macs including M1. After updating to macOS 26 (Tahoe), inference on M1 Macs fails — either producing garbage output or crashing. The same binary, same .mlpackage, same inputs work correctly on M2+. O

Hi, I do have a strange behavior in my development environment on a Mac mini (M4) running 26.2 and Xcode 26.3. Everything was working as expected. My project had a stable state and I wanted to enable iCloud support. As result I could not run the app any more because code signing failed with the message that my profile does not include the above entitlement. On my notebook (M2) with XCode 26.3 everything is working. Im am using GIT and both computers have identical code. The code compiling and running on my notebook will not run any more on my Max mini. Any help to find what might have broken the code signing and how it could be fixed? Thanks in advance.

Hello everyone. We have an app that has been on the App Store for several years, originally distributed for iOS and iPadOS only. Recently, we enabled Mac (Designed for iPad) and started distributing macOS-compatible builds. Current situation: The app is available and downloadable from the macOS App Store and runs correctly on Apple Silicon Macs. The same app/build appears in TestFlight on macOS, but cannot be installed. TestFlight shows the message: “This app can only be tested on an iOS device.” This suggests the app itself is Mac-compatible, but TestFlight is treating the build as iOS-only. Environment and checks performed: Mac is Apple Silicon. App Store Connect app-level availability for Mac (Designed for iPad) is enabled. The app is not Mac Catalyst; it is a UIKit iOS/iPadOS app. Distribution is done via GitLab CI. CI uploads use an App Store provisioning profile (Apple Distribution), not development or ad-hoc. iPhone and iPad TestFlight installs work as expected. Info.plist verification: UIRequiredDevic

Hi Guys, Hope you're well! I am consistently encountering a build warning in Xcode 26 that prevents proper symbolication of crash logs. The warning states: warning: (arm64) /Users/mickey/Library/Developer/Xcode/DerivedData/CalendarSync-bjuvwxojzofqzzcmzzpdozbujrge/Build/Products/Debug-iphoneos/CalendarSync.app/CalendarSync empty dSYM file detected, dSYM was created with an executable with no debug info. Steps to Reproduce: Open the project in Xcode 26. Build the project for a physical iOS device (arm64) or Archive the project. The warning appears during the Generate dSYM phase of the build process. Troubleshooting Steps Already Taken (Issue Persists): Set 'Enable Debug Dylib Support' to No. Verified 'Debug Information Format' is set to 'DWARF with dSYM File'. Verified 'Generate Debug Symbols' is set to Yes. Set 'Strip Debug Symbols During Copy' and 'Strip Linked Product' to No. Performed 'Clean Build Folder' and manually deleted the DerivedData folder. The issue persists regardless of these

I’m seeing what looks like a compiler / macro-expansion / build-pipeline issue. Environment: Xcode 26.4 RC (17E192, latest); I believe it is also reproducible on earlier versions. github source code I reduced this to a very small macOS/iOS app plus a local macro package. The app logic is trivial, but app exits immediately on launch with code 138 Important observations: If I inline everything into a single file, the problem disappears. I also see an error like this during investigation: The file path does not exist on the file system: /var/folders/.../swift-generated-sources/@__swiftmacro_18MacroFeedbackRepro20MountActivationState17PreservedRawValuefMm_.swift That makes me suspect this is not an application logic issue, but something in macro expansion / generated source handling / compiler pipeline.

I'm distributing a macOS .pkg installer signed with Developer ID Installer and notarized via notarytool. On macOS 26.3 (Tahoe, Build 25D125), the package is rejected by Gatekeeper when downloaded from the internet. What works: pkgutil --check-signature → signed, Developer ID Installer, full chain (G2 intermediate + Apple Root CA) xcrun stapler validate → The validate action worked! xcrun notarytool info → status: Accepted The .app inside the .pkg passes spctl -a -vvv → accepted, source=Notarized Developer ID What fails: spctl -a -vvv --type install mypackage.pkg → rejected, origin=Developer ID Installer Raw assessment: assessment:remote = true, assessment:verdict = false Double-clicking the downloaded .pkg shows only Move to Trash / Done (no Open option) syspolicyd log: meetsDeveloperIDLegacyAllowedPolicy = 0 (expected, since the cert is new), but no notarized match is logged Certificate details: Developer ID Installer, issued Feb 28, 2026, valid until 2031 OID 1.2.840.113

Some SF Symbols (wifi for example) render fine with the variable. But many, mostly ones with the circle being variable, do not seem to work. The SF Symbols app shows them rendering with a variable fine. But in code it doesn't work. Am I missing something or is there a reason? var body: some View { HStack { Image(systemName: 01.circle, variableValue: 0.5) Image(systemName: figure.wave.circle, variableValue: 0.5) Image(systemName: wifi, variableValue: 0.5) }.font(.largeTitle) } }
