There is a WWDC session about this cool instrument to detect hangs on-device: https://developer.apple.com/videos/play/wwdc2022/10082/ I very like this tool; it's handy and gives useful stack traces, but the threshold of 250 ms is practically too high to use in a testing environment. It would be better if there was an option like 100 ms or something like that. I think most of the people can see the scrolling hang with a duration of 100-250 ms, and it would be cool to detect such hangs with this instrument. Is there a way to set a lower threshold, or can Apple consider adding such a threshold? Thank you!

Hello, I've upgraded both of my Apple TVs to tvOS 18. Since then, my app developed with SwiftUI has become almost unusable due to severe lag, particularly when scrolling in a LazyVStack. On the A1625 (Apple TV HD), the lag can last up to 20 seconds, while on the A2843 (Apple TV 4K, 3rd generation, Wi-Fi + Ethernet), it’s about one second. I can consistently reproduce the issue with this minimal example: @main struct MyApp: App { var body: some Scene { WindowGroup { ScrollView { LazyVStack { ForEach(0..<1000) { nb in Button("Item \(nb)") {} } } } } } } Using Instruments, I found that the hang is related to this call: 389.00 ms 71,4 % 6.00 ms +[_UIFocusRegionEvaluator __regionsByEvaluatingOcclusionsForBaseRegions:occludingRegions:baseRegionsCanOccludeEachOther:inSnapshot:] Unfortunately, I can't attach the Instruments trace directly here, but you can download it from this link: https://drive.google.com/file/d/1sEIwXhr7_ajjRHZevCIW6jNOlPjaeU6L/view?usp=sharing Important notes: The same screen, when written in UIKit, runs smoothly on both devices. After performing a factory reset on the older device, the performance issue disappeared. However, as you can imagine, I’m already receiving complaints from users who are understandably unwilling to reset their devices. Does anyone know of a workaround until this is addressed by Apple?

Hello, I'm trying to use the itmstransporter installer (iTMSTransporter_installer_linux_aarch64_3.3.0.8.sh ) I downloaded from my Mac using the following command: iTMSTransporter -m downloadInstaller -arch aarch64 -os Linux -destination ~/Downloads when I move it on the Linux machine and I run it I receive the terms to be approved, I write Yes and return, then it asks "Continue? [yes or no] " and again I write yes and return, but immediately the command quit without any output. Any idea what's happening?

Hi everyone, I'm developing a visionOS app using SwiftUI and RealityKit, and I'm encountering an issue with the pivot points of primitive shapes created in Reality Composer Pro. Scenario: When I use Reality Composer Pro within Xcode to add primitive shapes (such as cubes, capsules, etc.) to my scene, the pivot points for these objects seem to be set incorrectly. The pivot is located far from the actual object, which affects transformations and positioning. Question: Is there a way to correct or adjust the pivot point for primitive shapes created in Reality Composer Pro? Additional Information: I’ve attached a screenshot illustrating the issue with the pivot point being misaligned. Any guidance on how to resolve this would be greatly appreciated. Thanks in advance for your help! Best, Siddharth

Trying to examine performance issues in Xcode Instruments using the Animation Hitches instrument in Xcode 16.0 beta 6 (16A5230g). When connected to my iPhone 15 Pro Max and I try to start a run with my app, it has an error “Failed to split user provided arguments: working directory doesn't exist” with timestamp “(Before Run Started)”. When running the app on an iOS simulator, the instrument runs fine—but I want to profile on a real device.
 Instruments > Settings, Recording Location set to Default and that directory does exist.

Hello! Is it possible to make App Thinning Size Report for app store distribution with command "xcodebuild -exportArchive -archivePath iOSApp.xcarchive -exportPath Release/MyApp -exportOptionsPlist ExportOptions.plist" ? https://developer.apple.com/documentation/xcode/reducing-your-app-s-size#Automate-the-generation-of-the-app-size-report I tried to do this by specifying "method": "app-store" in ExportOptions.plist, but it doesn't work. I get an empty app-thinning.plist as output. But when I specify "method": "enterprise", it works correctly. Is it true that App Thinning Size Reports are only generated when the archive is exported for Ad Hoc or Enterprise distribution (not for App Store) ?

Hi, I'm sorry if my question is Hello, I apologize if my question seems worthless to you. I'm just starting out, it's my first day as an apprentice learning this programming language, and I don't have any community or mentor to help me. I searched for my answer in the Forum but couldn't find a solution, so I'm asking my question here. How can I, at the start of a project, choose an emulator device that includes other iPhones besides the 15 and 13? I'm looking for the iPhone 14. I'm currently using Xcode version 15.4. Thank you for your attention to my question. Have a great day.

Hi, Trying to convert the lsaw.csstoredump file in a sysdiagnose directory in to a human readable format. The readme file in sysdiagnose indicates ".csstoredump files: sysdiagnose generates the output of lregister/lsaw in a binary form. To convert these .csstoredump files to text files, use the following command: lsaw dump --file "PATH TO DUMP FILE" > lsaw.txt These files can also be opened in CSStore Viewer." But no such command lsaw exists, at least not on macOS 14. No CSStore viewer either. Any ideas where I can find this utility or convert the file? I know it's in .gz format so have also tried just decompressing it but it is still in a binary format. Also tried running strings on it but not useful. Thanks!

I want to test app launch performance in my project. Therefore I tried to use performance test with measure func and XCTApplicationLaunchMetric. But after test completion there is no any result with average time. Here is a test example: func testLaunchPerformance() throws {         if #available(macOS 10.15, iOS 13.0, tvOS 13.0, watchOS 7.0, *) {             // This measures how long it takes to launch your application.             measure(metrics: [XCTApplicationLaunchMetric()]) {                 XCUIApplication().launch()             }         }     } But when I create a new empty project and add the same performance test – it works and shows app launch results. 1st image is a real project test – there is no test result. and the 2nd image is a demo empty project test – it has performance result diagram. I am running test on MacBook with M1 Pro chip. However, when my colleague is running the same performance test on our real project with Intel based MacBook Pro – all is fine, it shows app launch results correctly as my demo project. I have no idea how it can be fixed, because it seems that it depends on M1 chip 🤷🏻‍♂️. May be somebody have a solution?

I have been able to get rid of reported memory leaks in Instruments not by fixing a leak but by adding some lines (like releasing a previous nil object) that convinced Instruments it is not a leak. But I am stuck are some I cannot stop Instruments from reporting. It reports a leak in this code if(expr.length&gt;0) { // add previous Atomic Atomic *atom = [[Atomic alloc] initWithString:[string substringWithRange:expr] isNumber:aNum]; [exprTokens addObject:atom]; [atom release]; } } and it underlines the substringWithRange method. I changed code to explicitly release atom and I assumed substringWithRange would return an autoreleased new string. I am aware Instruments tells you where the leaked object is created and not where it is leak, but only things created here are atom and a sub string and atom is released immediately. The initWithString method might do it, but I don't find anything there. Also, while running instruments, this code is 8542 times (I am pretty sure always in the same context) and Instruments says it only leaks 61 times. I don't now if there is misunderstanding are a code problem?

I'm developing an app where users can select items to add to a screen, similar to creating a Canva presentation or choosing blocks in Minecraft. However, I'm encountering an issue with energy usage. When users click the arrows to browse different items, the energy use spikes significantly. Although it returns to normal after a while, continuous clicking causes the energy use to skyrocket. The images I'm using are 500x500 pixels. Ideally, I would like to avoid caching all the images, as the app might have up to 500 items and caching them all would consume too much memory. I have tried numerous way to avoid this but I just can’t seem to make it work. Would anyone know how to avoid such problem? I have included a picture of the energy use when just opened, and one after like 10 seconds of continuously clicking on an arrow to see more items. Also a picture of how the app looks. struct ContentView: View { struct babyBackground { var littleImage = "" } @State var firstSet: [babyBackground] = [ babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape"), babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape") ] @State var secondSet: [babyBackground] = [ babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape"), babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), babyBackground(littleImage: "anotherShape"), babyBackground(littleImage: "circle") ] @State var thirdSet: [babyBackground] = [ babyBackground(littleImage: "circle"), babyBackground(littleImage: "square"), babyBackground(littleImage: "triangle"), ] let columns: [GridItem] = Array(repeating: .init(.flexible()), count: 4) func createBackgroundGridView(for backgrounds: [babyBackground], columns: [GridItem] ) -> some View { LazyVGrid(columns: columns, spacing: 10) { ForEach(0..<backgrounds.count, id: \.self) { index in Button(action: { }, label: { if let path = Bundle.main.path(forResource: backgrounds[index].littleImage, ofType: "png"), let uiImage = UIImage(contentsOfFile: path) { Image(uiImage: uiImage) .resizable() .frame(width: 126, height: 96) } }) } } .padding() } @State var indexOn = 0 var body: some View { HStack{ Button(action: { indexOn = (indexOn == 0) ? 2 : indexOn - 1 }) { Label("", systemImage: "arrowtriangle.left.fill") .font(.system(size: 50)) } Spacer() ScrollView { switch indexOn { case 0: createBackgroundGridView(for: firstSet, columns: columns) case 1: createBackgroundGridView(for: secondSet, columns: columns) case 2: createBackgroundGridView(for: thirdSet, columns: columns) case 3: createBackgroundGridView(for: thirdSet, columns: columns) default: createBackgroundGridView(for: firstSet, columns: columns) } } .frame(maxWidth: .infinity, maxHeight: .infinity) Spacer() Button(action: { indexOn = (indexOn == 2) ? 0 : indexOn + 1 }) { Label("", systemImage: "arrowtriangle.right.fill") .font(.system(size: 50)) } } } } Energy Use when app starts: Energy use after clicking for about 10 seconds: App UI:

Hello, I see the Instruments app has gotten a nice upgrade for Xcode 16. There is one issue left that has been bothering me though. If my app is installed inside the "Application" folder, and I then try to launch Instruments for a new build of the same app from within XCode, Instruments will run the app installed in "Applications" instead of running the app I just built. The problem with this, is that it's very easy to accidentally profile an old version of your app, and come to the wrong conclusions. I've created a video showing this issue: https://youtu.be/IloFsQQFgSw

When using instruments leaks to record a trace, and then using the xctrace symbolicate command to symbolize it, it will prompt that the symbol file cannot be found. record command like this: ‘ xctrace record --instrument Leaks XXXXXXXX"， only use --instrument parameter nor --template parameter. symbolicate commadn like this: 'xctrace symbolicate --input xx.trace --output ddd. trace --dsym /Users/xxxx/Downloads/dSYM' Below is the symbol translation error message： Gathering trace symbols info [2/2] Succeeded: 2/2 [Error] Cannot resymbolicate this trace: No dSYMs were found or relevant to this trace.

Hello, anyone deal with an issue in the App Store Connect (trends section)? Few hours ago I logged in and checked the trends page, but it does not load. It takes a while and then the error: "An unexpected error occurred. Try reloading the page. If the problem persists ..." is being shown I guess it's an Apple issue or am I the only one experiencing this problem? Best, Jackson

what could be the reason? i open my app in xcode 16. build completes successfully. i am only given the options to simulate in iOS 17, 17.2 or 17.5. none of the devices show the option to run in iOS 18. but i am able to go into the simulator and through file and open the iOS 18 simulator. just not able to run my app in there. my app is set in xcode to run with a minimum of iOS 16. any ideas?

I am building an old app with very old dependencies on the new xcode. Download xcode 14.2 or below looks like a solution. I am not sure if that's possible.
