So I have a MacOS application that was working just fine before Xcode 16. The Widgets are not working anymore. The main application and the widgets share a file in a common App Group. The widget app now get a permission error when accessing the file. Also, the Widget Kit simulator keeps crashing. I also try to start a new project in Xcode, add a target with a Widget extension with an App Intent and run it, and it also crashes. Sometimes, it doesn't crash but just display the error: "Failed to load widget. The operation couldn't be completed. (WidgetKit_Simulator.WidgetDocument.Error error 2.). Edited to attach WidgetKit error log widgetKitError.txt

Any Apple Engineers out there who wrote this error message? DeviceLinkListener.c:_copyMobileDeviceValue| ERROR: Attempt to copy a value from an unpaired device. Cowardly refusing to do so ERROR: .... Cowardly refusing to do so Any thoughts? I click on 'trust this computer' (on the iPhone) and the error is triggered.

I recently upgraded my Mac to Sequoia 15.0 (24A335) so I had to upgrade Xcode & command line tools to 16. I need command line tools 15 also on the mac due to some of the legacy projects depending on it. I want to install command line tools 15 and choose it in the Settings-->Location, but Xcode doesn't display "Command line tools 15" although i download & install from https://developer.apple.com/download/all/

I’d like to migrate my watchOS app (bundled with an iOS app) from a dual-target to a single-target setup. I remember Xcode used to have a menu item (Editor -> Validate Settings) that would prompt you to initiate the migration process. However, I can’t seem to find a ‘Validate Settings’ option in the latest Xcode 16. Has "Validate Settings" been removed in xcode16 ? Thanks!

When my mac is upgraded to 13.7, some shortcuts to Xcode are not available, such as command + left, command + right, command + Backspace

Why won't XCode 16 run without iOS 18 installment?

In the latest version of Xcode, breakpoints are not displaying correctly, making it difficult to track code behavior. Previously, Xcode allowed you to step through each function, showing clear execution steps and allowing interaction to debug effectively. However, now it only shows memory addresses without providing meaningful insights, limiting the ability to interact with or test the code as it's being developed. Is anyone else experiencing this issue, or does anyone know of a workaround?

Since its update to iOS 18.0, I have not been able to use the Simulator in Xcode at all. It is stuck loading for a very long time, and then it crashes. I managed to get it to start once, but it used up all of my system's memory immediately. I have not had any problems with the Simulator before the iOS 18.0 update. Additionally, after the Simulator crashing, the StoryBoard usually stops working as well, until I restart Xcode. (I use an M1 MacBook Air with 8GB of RAM)

When I try to run my app on my iPhone, from Xcode, I get a popup that says Unable to Install "AppName". There is some text in the popup. Here's the first part of it. (I replaced the real app's name with "AppName".) Anyone know how to fix this?

I was granted permissions for family controls distribution for the main target of my app. Do I also need to request permission for the other targets like ShieldConfiguration, ShieldActionExtension, etc.? If no, how can i add the distribution capabilities to those targets?

hey all today for some reason im getting Unsupported SDK or Xcode version valdation failure when uploading to app store connect. I haven't changed anything and i was able to upload jsut a few days ago with same version of xcode. Its xcode 16.0 anyone else getting this? Maybe its a server side issue?

I have been working on Task Management app for macOS (currently using maOS 15.0 on a M1 MacBook Pro) for a while. Nothing fancy, it uses SwiftUI and Core Data. My problem: I make changes to the app, then run it in the simulator and see if everything works as expected. This works fine for maybe three weeks, until at one point it suddenly stops working – I make a minor change, click "Run" in Xcode (this happens in Xcode 15.x and now Xcode 16), the app icon bounces in the dock, but then no window opens. The app is built and I can see in the console that there are the usual notifications, but I cannot use the simulator anymore. I tried cleaning the Build Folder, resetting the Computer, reinstalling Xcode – nothing helps. What occasionally helps is renaming the Bundle Identifier, but now I only got it to run the simulator once more, then it stopped working. The only solution I have is to manually rebuild the whole app under a new name – that is, recreating the Core Data model and all files, which I have done three times. And now it stopped working again. Does anyone know why this could be? I think Xcode 16 gives me a notification I did not get from Xcode 15: "NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed" I could not find anything on this. Any ideas are greatly appreciated.

While I am able to use #Preview to preview a Widget, it seems to be not possible to easily preview a Widget placeholder. With a "classic" preview I can use .redacted(reason: .placeholder), but this has limitation e.g. it will ignore .contentMarginsDisabled() struct MyWidget_Previews: PreviewProvider { static var previews: some View { Group { MyWidgetView(entry: SimpleEntry(date: .now, emoji: "😀")) MyWidgetView(entry: SimpleEntry(date: .now, emoji: "😀")) .redacted(reason: .placeholder) } .previewContext(WidgetPreviewContext(family: .systemMedium)) .containerBackground(.white, for: .widget) } } If I use #Preview, the .redacted modifier won't work, and I seem to have to put it in the MyWidget implementation. #Preview(as: .systemMedium) { MyWidget() } timeline: { SimpleEntry(date: .now, emoji: "😀") SimpleEntry(date: .now, emoji: "🤩") } Am I missing something?

When tapping on "password" in the accessory view above the keyboard, no password manger is opened. The keyboard just closes and re-opens. I have made sure a password exists and is available to be used. I have replicated this within my own app, but also from within the Settings app on the simulator (see attached gif) so I am confident it is not a coding issue on my side. I have replicated it on both iOS 17 and iOS 18 I am using Xcode Version 16.0 (16A242d) I am running macOS Sonoma Version 14.7 (23H124) I am fairly confident I have not experienced this when working on another clients app. I was using Xcode 15 for that so not sure if this is something introduced with Xcode 16.

Hello, I’ve been experiencing repeated errors when trying to install my app via flutter run --release on iOS devices using Xcode 16.1 (build 16B5014f) on macOS 15.1. When running the app in debug mode, it sometimes works but takes a long time to install. However, the installation in release mode fails consistently. This issue occurs on both my iPhone and iPad, both running iOS 18.1 and iPadOS 18, respectively. The errors keep rotating between three variations: Error 1: CoreDeviceError 3002 Error executing devicectl: ProcessException: Process exited abnormally with exit code 1: ERROR: Failed to install the app on the device. (com.apple.dt.CoreDeviceError error 3002 (0xBBA)) Connection with the remote side was unexpectedly closed : "XPCErrorDescription" => "Connection interrupted" Error 2: CoreDeviceError 12010 Error executing devicectl: ProcessException: Process exited abnormally with exit code 1: ERROR: The developer disk image could not be unmounted on this device. (com.apple.dt.CoreDeviceError error 12010 (0x2EEA)) Could not read from the device. (com.apple.dt.CoreDeviceError error -402653180 (0xE8000004)) Error 3: CoreDeviceError 1000 Error executing devicectl: ProcessException: Process exited abnormally with exit code 1: ERROR: The specified device was not found. (com.apple.dt.CoreDeviceError error 1000 (0x3E8)) What I've Tried So Far: Reinstalled Xcode, cleaned the build folder, and cleared DerivedData. Tried using both an iPhone and an iPad running iOS 18.1 and iPadOS 18.0. Ensured that Developer Mode is enabled on both devices. Disabled VPNs (Bitdefender) and firewall settings. Manually mounted the developer disk image via Xcode. Restarted the Mac, Xcode, and devices multiple times. Despite these steps, the errors persist, and I’m unable to install the app on either device. I would appreciate any guidance or suggestions on how to resolve this issue. System Information: macOS Version: 15.1 (Build 24B5055e) Xcode Version: 16.1 (Build 16B5014f) Devices: iPhone 14 running iOS 18.1, iPad running iPadOS 18.0 Thank you in advance!

I've upgrade my macbook m3 pro to macOS 15, I have 2 iPhones (12 Pro and 16 Pro) - both on iOS 18 and have 3 versions of Xcode installed (15.4, 16.0, 16.1-2 beta) For the past week I'm unable to develop on my physical device and checked all the threads in this forum for a workaround to disable the "Connect via Network". If I'm not connected to VPN on any of my devices, I get the process attached via network after ~20 minutes, but if I try to do it while on VPN it takes forever (not even sure, can't spend 1 hour waiting to be attached or not) What can I do to disable the "Connect via Network" and why is enabled by default and greyed out?

Hi there, In a project that I am working on, whenever I try running instruments for allocations to see the memory allocations that are happening under the hood, I see the statistics, and the traces updating, however the chart never updates. I have made new projects on the machine, and I have tried different Xcode versions, and they all show the chart just fine. I have tried running the project on other machines with no success. I have double checked the arguments and options on the active schema I am trying to profile with the schema of a new project and they are identical. Here is a picture of how it looks: My questions are as follows: What properties and settings can disable the chart from showing up? What diagnostic steps recommended that I should take? I can not share a reproducible as this is the only project I have with this problem and it is not mine, but please tell me if there is anything else I can provide in order to debug this. All the best Parsa

I'm running Xcode 16 on Sequoia 15.0 with a M1 Max Pro. The download completes, but every now and then (I've counted 3 times so far), after logging in to my computer and launching Xcode (not necessarily from a restart , the Predictive Code Completion Model starts downloading again. Any solution? Thanks.

I have an issue with web ads not working in Safari versions earlier than 16.4. While debugging Safari Web Ads I found out that I don't get postbacks from versions 16.4 or below from Safari, although there are no technical limitations and the documentation says that web ads should work starting from versions 16.1 https://developer.apple.com/documentation/storekit/skadnetwork/skadnetwork_release_notes/skadnetwork_4_release_notes For ads that appear in an app, the app is built with iOS 16.1 SDK or later. For web ads, the ad appears in Safari 16.1 or later.`` Maybe I missed something and Apple didn't update the documentation, is that normal? Maybe it's related to this release and there was a technical problem with Apple? https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-16_4-release-notes/#SKAdNetwork Has anyone encountered the same problem and how did you fix it? Thanks!
