SwiftUI preview hangs on "Preparing iPhone Simulator for Previews". Also simulator hangs when trying to build and run. This occurred after I installed iOS 17 simulator. I tried reverting back to an iOS 16 version of the simulator, but haven't figured out how to do that. Build and run to an iPhone device works fine. Any ideas would be appreciated. Thanks.

The new console in Xcode 15 is so terrible bad. Is it possible to get back the old console ?

I reinstalled the macOs from macOS recovery, Then installed the new Xcode 15, Everything worked fine but when I tried to commit my code the commit button does not showing. The image from my Xcode app:

Attempting to launch a widget in Debug mode on Sonoma from Xcode 15 is failing with the following message: attach failed (Not allowed to attach to process. Look in the console messages (Console.app), near the debugserver entries, when the attach failed. The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.) Looking in console I see this message: macOSTaskPolicy: (com.apple.debugserver) may not get the task control port of (MacGalleryWidget) (pid: 1851): (MacGalleryWidget) is hardened, (MacGalleryWidget) doesn't have get-task-allow, (com.apple.debugserver) is a declared debugger(com.apple.debugserver) is not a declared read-only debugger What Xcode settings should I be looking at to rectify this? I suspect I may have something that's out of whack.

I'm trying to copy some files from the Finder on macOS 14 to several Simulator instances running iOS 16 and 17. When I right-click the file in the Finder, I can select Share > Simulator, then a share dialog pops up where I select the relevant Simulator and click on Send. According to this official help topic, the Files app should open allowing me to choose the destination, but instead nothing happens and the shared file is nothing to be seen. What's the issue?

I am suddenly unable to connect to my iPhone (running iOS 17.0) in Xcode (either 15 or the last 15 beta). I get this error: The developer disk image could not be mounted on this device.. Error mounting image: 0xe8000115 (kAMDMobileImageMounterDevicePropertyQueryFailure: Failed to query device property.) I am able to see the disk image iOS_DDI.dmg in the Finder by opening /Users/cmonsour/Library/Developer/DeveloperDiskImages/ I have restarted both computer and iPhone, re-enabled Developer Mode, cleared Derived Data. I am not running a VPN. I am running the latest Xcode. I upgraded from Ventura to Sonoma with no improvement. Any help appreciated.

Hi, I'm trying to use the appIcon command of devicectl. I'm connecting to an iPhone 14 Pro running iOS 17.0.2. xcrun devicectl device info appIcon --help OVERVIEW: Request app icon generation from this device. This command searches for an app installed on this device and requests for its icon to be generated. USAGE: devicectl device info appIcon [<options>] --device <uuid|ecid|udid|name> --allow-placeholder <allow placeholder> --width <width> --height <height> --scale <scale> DEVICE OPTIONS: -d, --device <uuid|ecid|udid|name> The identifier, ECID, UDID, or name of the device. COMMAND OPTIONS: --app-bundle-id <app bundle identifier> Look for app icon information with the given application bundle identifier on device. Note: If both app-bundle-id and app-path are provided, only app-path will be used. --app-path <app path> Look for app icon information at the given application path on device. Note: If both app-bundle-id and app-path are provided, only app-path will be used. --allow-placeholder <allow placeholder> Allow placeholder icons to be generated. Note: Passing `true` will allow placeholder icons to be returned. Allowing placeholder icons will ensure no I/O is done on device. If you want to make sure you get the icon most accurate to your request -- which could use more resources on the device -- set this to `false`. --width <width> Request app icon generation with the specified width. --height <height> Request app icon generation with the specified height. --scale <scale> Request app icon generation with the specified scale. --destination <destination> Write the image (in png format) to the provided file on the host device. OUTPUT OPTIONS: -v, --verbose If given, provide more logging output than normal. -q, --quiet If given, output will include only errors. -t, --timeout <seconds> The overall command timeout in seconds. If this limit is exceeded the command is abandoned as a failure. -j, --json-output <path> An optional path to write a JSON file with command results. Note: JSON output to a user-provided file on disk is the ONLY supported interface for scripts/programs to consume command output. -l, --log-output <path> An optional path to write all logging otherwise passed to stdout/stderr. OPTIONS: --version Show the version. -h, --help Show help information.

Setting CFBundleVersion in a Run Script Build Phase (using PlistBuddy or agvtool) no longer works since Info.plist is being auto-generated for newly created Xcode projects. So what is the recommended way to achieve this now?

I regularly talk to developers debugging hard-to-reproduce problems. I have some general advice on that topic. I’ve posted this to DevForums before, and also sent similar info to folks who’ve opened a DTS incident, but I figured I should write it down properly. If you have questions or comments, put them in a new thread here on DevForums. Put it in the Developer Tools & Services > General topic area and tag it with Debugging. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Using a Sysdiagnose Log to Debug a Hard-to-Reproduce Problem Some problems are hard to reproduce in your office. These usually fall into one of two categories: Environment specific — This is where some of your users can easily reproduce the problem, but you can’t reproduce it in your environment. Intermittent — In this case the problem could affect any user, but it’s hard to predict when a given user will see the problem. A key tool in debugging such problems is the sysdiagnose log. This post explains how to make this technology work for you. IMPORTANT A sysdiagnose log might contain private information. If you ask a user to send you a log, make sure they understand the privacy impact of that. If you want to see how Apple handles this, run the sysdiagnose command on a fresh Mac and read through it’s initial prompt. Sysdiagnose Logs All Apple platforms can generate sysdiagnose logs. For instructions on how to do this, see our Bug Reporting > Profiles and Logs page. The resulting log is a .tar.gz file. Unpacking that reveals a bunch of files. The most critical of these is system_logs.logarchive, which is a snapshot of the system log. For more information about the system log, including links to the documentation, see Your Friend the System Log. This log snapshot includes many thousands of log entries (I just took a log snapshot on my Mac and it had 22.8 million log entries!). That can be rather daunting. To avoid chasing your tail, it pays to do some preparation. Preparation The goal here is to create a set of instructions that you can give to your user to capture an actionable sysdiagnose log. That takes some preparation. To help orient yourself in the log, add log points to your code to highlight the problem. For example, if you’re trying to track down a keychain problem where SecItemCopyMatching intermittently fails with errSecMissingEntitlement ( -34018 ), add a log point like this: import os.log let log = Logger(subsystem: "com.example.waffle-varnish", category: "keychain") func … { let err = SecItemCopyMatching(…) log.log("SecItemCopyMatching failed, err: \(err)") } When you look through a log, find this specific failure by searching for SecItemCopyMatching failed, err: -34018. You might also add log points at the start and end of an operation, which helps establish a time range of interest. Log points like this have a very low overhead and it’s fine to leave them enabled in your released product. However, in some cases you might want to make more extensive changes, creating a debug build specifically to help investigate your problem. Think about how you’re going to get that debug build to the affected users. You might, for example, set up a special TestFlight group for folks who’ve encountered this issue. Go to Bug Reporting > Profiles and Logs and look for debug profiles that might help your investigation. For example, if you’re investigating a Network Extension issue, the VPN (Network Extension) debug profile will enable useful debug logging. Now craft your instructions for your user. Include things like: Your take on the privacy impact on this Instructions on how to get the necessary build of your product If there’s a debug profile, instructions on how to install that Instructions on how to trigger the sysdiagnose log And on how to send it to you IMPORTANT Make sure to stress how important it is that the user triggers the sysdiagnose immediately after seeing the problem. Finally, test your steps. Do an initial test in your office, to make sure that the log captures the info you need. Then do an end-to-end test with someone who’s about as technically savvy as your users, to make sure that your instructions make sense to Real People™. Prompting for a Sysdiagnose Log In some cases it might not be obvious to the user when to trigger a sysdiagnose log. Imagine you’re hunting the above-mentioned errSecMissingEntitlement error and it only crops up when your product is performing some task in the background. The user doesn’t see that failure, they’re not even running your app!, so they don’t know that action is required. A good option here is to add code to actively monitor for the failure and post a local notification requesting that the user trigger a sysdiagnose log. Continuing the above example, you might write code like this: func … { let err = SecItemCopyMatching(…) log.log("SecItemCopyMatching failed, err: \(err)") if err == errSecMissingEntitlement { … post a local notification … } } Obviously this is quite intrusive so, depending on the market for your product, you might not want to deploy this to all users. Perhaps you can restrict it to your internal testers, or your external beta testers, or a particularly savvy set of customers. You can use the applefeedback URL scheme to make it easy for users to run Feedback Assistant. For more info about that, see Developer > Bug Reporting. Looking at the System Log Once you have your sysdiagnose log, unpack it and open the system log snapshot (system_logs.logarchive) in Console. The hardest part is knowing where to start. That’s why adding your own log entries, as discussed in Preparation, is so important. A good general process is: Search for log entries from your subsystem. An easy way to initiate that search is to paste the text subsystem:SSS, where SSS is your subsystem, into the Search field. Continuing the above example, find that log entry by pasting in subsystem:com.example.waffle-varnish. Identify the log entry that indicates the problem and select it. Then remove your search and work backwards through the log looking for system log entries related to your issue. The relevant log entries might not be within the time range shown by Console. Customise that by selecting values from the Showing popup in the pane divider. Once you have a rough idea of the timeframe involved, select Custom from that popup to focus on that range. If the log is showing stuff that’s not relevant to your problem, Console has some great facilities for filtering those out. For the details, choose Help > Console Help. Talk to Apple A key benefit of this approach is that, if your investigation suggests that this is a system bug, you can file a bug report and attach this sysdiagnose log to it. The setup described above is exactly the sort of info needed to analyse the bug. Likewise, if you start a thread here on DevForums about your issue, your friendly neighbourhood DTS engineer will find that sysdiagnose log very handy.

I have a project that has a number of plugins in it. They are compiled and placed in the correct location and the build runs fine in the Debug / Release schemes. If I archive the build with Xcode 15 the resulting build generates a number of errors symbol not found in flat namespace '_OBJC_CLASS_$_XXXX for various classes that are part of the main application including the AppDelegate and other classes. This does not occur with Xcode 14.3.1 or previous versions. It still occurs in Xcode 15.1 beta 1. This happens regardless if I notarize the build with Apple or not. Has anyone seen anything like this? Any ideas how to resolve it? My current workaround is to use xcodebuild to compile a Release build and notarize that build.

I just finished my first mobile app using .Net Maui. I have created all of the required certificatee, identifier, and profile in my Apple developer account and downloaded them to my MacAir. On my Windows machine I connect to my MacAir in VS2022 and build my release. Then I go to publish and I get this error: Cannot create an IOS archive 'AgentManagerMobile'. Process cannot be executed on XMA server. MessagingRemoteException: An error occurred on client Build1647067 while executing a reply for topic xvs/build/16.4.7067/execute-task/{AppName}/399e8ad002fWriteAppManifest ArgumentNullException: Value cannot be null. Parameter name: path2 What is parameter path2? Can anyone help with solving this? Thanks, Phill

This is really a disgusting function and I can't turn it off. Because the check box is grey, no way to turn it off. Even I connect my device via cables. Debug becomes slow. Although I connect my device via cable. And I'm developing a VPN application, it's rediculous that once I connect VPN from my device, Xcode will disconnect from my device. I can't stand this function any m ore. Does anyone know how to turn it off?

Problem: iOS 16.4 runtime targets are not available for selection, however the 16.4 simulator shows as installed under "Manage run destinations" Config: Xcode 15.0, Sonoma 14.0, M1 Mac-Mini Background: I write and maintain apps for my business unit. A co-worker dropped a phone on my desk and said 'The app doesn't work anymore, can you fix it'. Well, it turns out the phone is running iOS 16.6. The OS had been upgraded. This sent me down the path of upgrading Xcode on a development Mac, which also forced a MacOs upgrade on me. The end result is I now have XCode 15 on Sonoma, but have an iOS 16.6 device that I'm trying to target. Since I don't have any iOS 17 devices I didn't install the 17.0 runtime. To install the "16.6 runtime" I went to: "Xcode - Settings - Platforms" and hit the + in the lower left and under "Previously released simulators" I selected iOS. I selected iOS 16.4 as it was the closest I could see to 16.6 so I'm assuming it still works with 16.6. It took a few attempts to download correctly, but it now shows up in my platforms as "iOS 16.4 Simulator 6.18 GB on disk". If I select "Product - Destination - Manage Run Destinations" I can see simulators for 10 different iOS devices (from iPad 10th gen to iPhone SE) all running iOS 16.4. Great! I must be ready to develop and test for 16.6. Right? Nope. In the dropdown beside my App name the only option that is shown to me is "iOS 17" and the "Get" button beside it. I was expecting to my iOS 16.4 simulators as available target destinations, but there's nothing other than "iOS 17 - Get". This is an old App that I'm maintaining so its deployment target is not new. Selecting a different iOS Deployment target doesn't have an effect. I tried going into Manage Run Destinations and selected my iPhone 14 simulator on iOS 16.4 as "show run destination always". - no change Older iOS version do not show as destinations. Anyone else encounter this? Did you figure it out? Help? Thx

Hi, I am creating a custom NSSecureUnarchiveFromDataTransformer in order to handle attributes of entities of type NSDateComponents. It all works and I did not see any warnings in the "Issue navigator" inside Xcode but with Xcode 15 I started seeing this warning: /Users/.../CustomNSSecureUnarchiveFromDataTransformer/CoreData:1:1 no NSValueTransformer with class name 'CustomSecureUnarchiveFromDataTransformer' was found for attribute 'testDate' on entity 'Item' My use case is very simple, I have this custom transformer: @objc(CustomSecureUnarchiveFromDataTransformer) final class CustomSecureUnarchiveFromDataTransformer: NSSecureUnarchiveFromDataTransformer { override class var allowedTopLevelClasses: [AnyClass] { return [NSDateComponents.self] } static let name = NSValueTransformerName(rawValue: String(describing: CustomSecureUnarchiveFromDataTransformer.self)) public static func register() { let transformer = CustomSecureUnarchiveFromDataTransformer() ValueTransformer.setValueTransformer(transformer, forName: name) } } which is set to the Core data entity's "Transformer": which leads to the warning in Xcode 15. App works just fine and there are no problems during run time, but this warning is shown and I want to fix it. Here is a simple test project https://github.com/VladimirAmiorkov/CustomNSSecureUnarchiveFromDataTransformer

I'm working on dext project (c++), Base SDK and Supported Platforms are set to DriverKit. #include causes errors: error "The iostreams library is not supported since libc++ has been configured without support for localization." error "<locale.h> is not supported since libc++ has been configured without support for localization." Also it's not possible to define custom log object: undeclared identifier 'os_log_create'. <os/log.h> included and os_log function is compiled correct. macOS as additional SDK did not help. Thanks a lot for any hint.

It would be nice for Apple to integrate chatgpt, Open AI, and create their own artificial intelligence. Siri is not equipped to answer questions that AI can. With increasing AI prevalence and usability, Apple is behind. Message to Apple: PLEASE UTILIZE AI TO MAKE APPLE THE BEST PLATFORM.

I received the MOBSF security check result PDF, where I found some "High" severity issues. 1.Binary makes use of insecure API(s) with high CWE: CWE-676: Use of Potentially Dangerous Function OWASP Top 10: M7: Client Code Quality OWASP MASVS: MSTG-CODE-8. The binary may contain the following insecure API(s): _sscanf, _memcpy, _fopen. 2.Binary makes use of the malloc function with high CWE: CWE-789: Uncontrolled Memory Allocation OWASP Top 10: M7: Client Code Quality OWASP MASVS: MSTG-CODE-8. The binary may use the _malloc function instead of calloc. I have utilized a static analyzer, but I am unable to identify the APIs such as _sscanf and others in my codebase. This issue is not being shown in Xcode IDE either. I have attempted static analysis in Xcode using the approach: Product -> Analyze, but I am still unable to identify the mentioned issues. Can anyone please help me overcome this scenario and successfully pass the MOBSF test? Thanks in Advance

Hi community: I found that after Xcode update from 14.3.1 to 15.0.1, my UITests fail only on the CI (Apple Xcode Cloud) because the use of boundElementsByIndex. Seems that the use of this property stale the main thread: Failed to resolve query: Unable to perform work on main run loop, process main thread busy for 30.0s Is it a known issue? Thanks

From time to time while I'm editing code, Xcode 15.0.1 says "The file 'project.xcworkspace' has been modified by another application" asking me "Keep Xcode Version" or "Use Version on Disk". I didn't see this before 15.0.1 (or 14.1.1). Who changed the file? What should my answer be? Thanks.

I'm trying to run my app on my iPhone and XCode is unable to detect it. Versions (as of time of writing, these are all the latest versions) XCode: 15.0.1 iOS: 17.1.2 macOS: Sonoma 14.1.2 What I've tried Updating all hardware to the latest versions. Restarting all hardware. Clearing cache/derived data. Using different USBC ports/cables. Using the XCode 15.1-Beta 3 (the latest beta) Clearing trusted computers and re-trusting Disabling Multipath Networking (solution for someone else on the dev forums) Creating a brand new xcode project. Disabling all wifi/bluetooth and reconnecting Using different wifi networks Calling mac support (they directed me back here) Scouring forums What happens I start by disconnecting my phone from my computer, clear trusted computers, restart xcode, and start (basically) from a completely blank slate. First I open XCode to my project. Then I connect my iPhone via USBC. I see that XCode says "iPhone not eligible while pairing in progress" (or something like that). I see on my phone that I must trust this computer, I hit trust, I enter my phone's passcode, then that disappears on my phone, and in XCode the message about eligibility disappears. I then click on the device selector to choose between either a simulator or a hardware device and under hardware I only see a message that says "No eligible devices connected to my mac". If I open the "Manage Run Destinations" organizer I see all the simulators there in the simulators tab, but when I go to the Devices tab, I see nothing. Sometimes when I go through this process, I can get a banner to appear up top, but still no device shows up on the left. The banner will show me that it is indeed my iPhone, but it will be missing information like "Serial Number" or "Capacity". Here's a screenshot of what I see. Keep in mind, this banner up top does not always show up when I go through this process. iPhone CAN be detected on my other laptop When I do this exact same thing on my other laptop, everything works just fine. Here are the specs I'm running on that laptop. (using the same cable/wifi network/etc) XCode 15.0.1 macOS: Ventura 13.6.1 iPhone 17.1.2 (I'm using the same iPhone) The only difference here being the macOS version. However, the problem started on my "broken" computer while I was running a previous major macOS version. This problem is actually what prompted my to do a system update to Sonoma. Please for the love of god, halp!!!
