I am using a Mac computer running macOS 15.5 with Xcode version 16.3 (16E140) and an iPhone XS Max on iOS 18.5. When debugging my app on the real device using Xcode, the app gets stuck on the launch screen and fails to proceed to the main interface. There is no output in the Xcode console, and the top of the window continuously shows "attaching to [app name] on [iPhone name]". Here are the details: The same issue occurred when the phone was running iOS 18.4.1. When I tested on another real device running iOS 17, the app launched and ran normally. I’ve tried clearing the cache, but it didn’t help. I deleted the ~/Library/Developer/Xcode/iOS DeviceSupport folder, let it re-download the necessary files, and ran the app again, but the issue persists. I’m currently out of ideas and would appreciate any assistance.

I am encountering an issue while running my CarPlay app in the simulator using CPListTemplate. On app launch, when I tap on the first item in the list and then tap on the second item, both items remain selected instead of only the latest tapped item. This behavior does not align with the expected single-item selection functionality. Has anyone else faced this issue? Is there a workaround or a known resolution for this behavior?

Hi! I am having trouble getting my app to build successfully or archive since an xcode update a few months ago. Below is the error that shows in the log. Thank you in advance for any help! Run custom shell script 'Run Script' Failed to package [project folder]. Command PhaseScriptExecution failed with a nonzero exit code

Hi! A couple of months ago my app was archiving just fine. Since an xcode update the build fails. Here is what shows at the end of the log. Thank you in advance for any help!

I am trying to setup a unversal linking for my new developing app. but it look like not function well. did any one have some examples or demo domains suggest to use? In fact finally my app is just internal using, user will not suppose connect to internet , how can I using the universal linking without a website ? Thanks

When referencing WebKit’s function callAsyncJavaScript, any iOS app crashes immediately on startup when running in simulator. On device, it does not crash. The error message is: dyld[9892]: Symbol not found: _$sSo9WKWebViewC6WebKitE19callAsyncJavaScript_9arguments2inAF17completionHandlerySS_SDySSypGSo11WKFrameInfoCSgSo14WKContentWorldCys6ResultOyyps5Error_pGcSgtF Furthermore, this only happens for some simulators. With Xcode 16.3, it’s simulators 18.0 and prior. With Xcode 16.4 RC1 it includes simulators iOS 18.5 and 18.4 but works correctly on earlier versions of simulator. The reproduction path is easy. Example file attached. This used to work about 3 weeks or a month ago, which is perplexing. As a workaround I replaced the function with evaluateJavaScript which does not crash, but that is not the desired method to use for us. The attached file can reproduce it easily - just refernece this view from the default ContentView in a new project. TestWebView.swift

I have a ContentView in my app which includes the line of code FileUploadProgressAttributes. this struct is defined in a file included in the target FileUploadProgressExtension. and it is an ActivityAttributes. in ContentView I imported FileUploadProgressExtension, and the xcode is able to find the FileUploadProgressAttributes during prebuild. but during build, it gives me Undefined symbols for architecture arm64: "FileUploadProgressExtension.FileUploadProgressAttributes.init(filename: Swift.String) -> FileUploadProgressExtension.FileUploadProgressAttributes the workaround i found is to add the file with the FileUploadProgressAttributes to my app's target, but I'm not sure if this is the right thing to do. When Xcode created the extension for me, it added the extension target as a target dependency of my app. so obviously if i added this file to my app target it makes the extension target pointless. First time working with widgets so I'm not sure if I'm missing something.

Hello, I'm trying to use devicectl to observe Darwin Notifications on my iPhone. Instructions: OVERVIEW: Observe a Darwin notification on a device. Note that this command will wait for 300 seconds by default before exiting. You can override this by providing a different --timeout value. USAGE: devicectl device notification observe --device <uuid|ecid|udid|name> --name <name> ... [--verbose] [--quiet] [--timeout <seconds>] [--json-output <path>] [--log-output <path>] DEVICE OPTIONS: -d, --device <uuid|ecid|udid|name> The identifier, ECID, UDID, or name of the device. COMMAND OPTIONS: --name <name> The name of the Darwin notification. This can be passed multiple times to observe multiple Darwin notifications. 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. Executed command: xcrun devicectl device notification observe --device XXX --name com.example.Notification Result: Darwin notification observation started. 300.0 seconds remaining: On iOS, I'm posting a Darwin notification using: CFNotificationCenterPostNotification(center, CFNotificationName("com.example.Notification" as CFString), nil, nil, true) My CFNotificationCenterAddObserver on iOS does receive this notification. But the devicectl does not. Also no results when I remove the observer on iOS. How can I send a notification in such a way that it is picked up by the devicectl observer?

Test Coverage shows "No Coverage Data" on Xcode 16.3. Code Coverage is checked in my scheme. The same configurations worked on Xcode 16.2 but don't work on Xcode 16.3. any update on when it will be fixed?

Ever since updating to Xcode 16.3, auto-completing variable names in lldb does not work. Is this a known bug? Is there a workaround to get it do auto-complete again?

I've recently upgraded to Sequoia and Xcode 16.3 (now 16.4RC) and a significant change I've noticed vs 16.2 is that the height of UINavigationBar components in storyboards and XIBs is incorrect. Xcode 16.2: Xcode 16.4: This only affects simulated metrics in storyboard / XIB files. I have been unable to find any discussion of this issue anywhere online. Is this actually an Xcode bug that has gone unnoticed / unfixed or is there some underlying intentional change here that I'm unaware of?

When you try to reset settings through the Apple Vision Pro simulator (VisionOS 2.4) you get an error "Preferences quit unexpectedly". Bug report: FB17666053

Is anybody able to save the autocreated testplan successfully with Xcode 16.3? I get a crash no matter what (different filenames, locations, machines, ...). Now created a template project: same thing. Xcode Version 16.3 (16E140) on macOS 15.5 (24F74) Known issue, or am I holding it wrong?

I know there has been issues with SFSpeechRecognizer in iOS 17+ inside the simulator. Running into issues with speech not being recognised inside the visionOS 2.4 simulator as well (likely because it borrows from iOS frameworks). Just wondering if anyone has any work arounds or advice for this simulator issue. I can't test on device because I don't have an Apple Vision Pro. Using Swift 6 on Xcode 16.3.

I am on MacOs 15.4.1 which is being deployed with an old version of Ruby ruby 2.6.10 and bundler version 1.17.2. I ran pod install after generating the pods with these versions and during the application compilation there have been several issues reported against pods code.

I have an iOS app and that has CarPlay enabled. I have Siri capability and the feature has been tested in Car. The voice commands are working perfectly fine. However, I am facing a weird issue as described below, The key NSSiriUsageDescription, is set to custom text in info.plist. After generating archive, I exported and checked the package contents, in which the the key NSSiriUsageDescription was reset to default text(Describe why your app needs Siri access) in the info.plist. I do not have any dynamic build process that's writing to the info.plist. Only the Siri key is being reset, rest of keys like camera/location permissions are intact. Kindly suggest what needs to be done at my end

Hello, Xcode seems to reset the canvas preview every time I open a file that does not have a preview. This is extremely annoying when working with two editor tabs. The resize happened before only after restarting Xcode since a few weeks it happens always when opening another file. The preview phone does not even take advantage of the resize. Is there a way to fix this? When I work with the file: After opening a file without preview and going back:

My project was created on a Mac with an Intel processor. Predictive code completion is enabled in Safari settings. The predictive model is loaded. However, the predictive typing does not work. For new projects it works. I took the following steps to fix this problem: 1. Ensure Indexing is Enabled and Up-to-Date: Enable Indexing: In Terminal, run the command defaults write com.apple.dt.XCode IDEIndexDisable 0. Clean and Rebuild: Go to "Product" > "Clean Build Folder" in Xcode. Then, rebuild your project. Check Derived Data: Xcode uses a "DerivedData" folder to store build artifacts. Try clearing this folder by navigating to ~/Library/Developer/Xcode/DerivedData and deleting its contents (you can use the command rm -rfv * in Terminal). 2. Verify Xcode Settings: Enable Predictive Code Completion: Go to Xcode > Settings > Text Editing > Editing and ensure "Predictive code completion" is checked. Check for Predictive Code Completion Model: In Xcode, go to Settings > Components. Ensure the "Predictive Code Completion Model" is downloaded and installed. If it's not, try downloading it by clicking the "+" button and selecting it. Disable and Re-enable: Try disabling predictive code completion in Xcode's settings and then re-enabling it. But this not help. I use latest macOS and Xcode.
