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.

when i use command of xctrace to record allocations data , the xctrace save crash . command like this : 'xctrace record --template Leaks xxxxxxxxx" The problem has been going on for a long time。 The following is the xctrace exception information： Starting recording with the Leaks template.

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

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:

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?

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. Building for simulators fail because of arm64. Phone is my only option. When using `react-native run-ios --device' it fails with sh -c '/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -find instruments 2> /dev/null' failed with exit code 17664: (null) (errno=No such file or directory) xcrun: error: unable to find utility "instruments", not a developer tool or in PATH.

I wanted to try the new Object Tracking. So I captured an object and uploaded it in Create ML in an Object Tracking project. I added my used file and set the viewing angle to "upright". Afterwards, I startet the training. After some time (around 2%), it stops and I receive following error message: "There isn't enough space. at "1921.blob". I tried it multiple times.

We are getting crash issue in our WKWebkit based Cordova application due to memory issues. However, for debugging the memory issue we are trying to use JavaScript allocations in the memory profiler of instruments. and while using it, the profiler automatically closes within few seconds, and we are not able to debug the underlaying memory issue in the WKWebKit. I

I saved a trace from the Leaks tool. However when I try to open the saved file, I get an error that says, "The document 'Generations.trace' could not be opened. Trace is malformed - run data is missing." This happens every time I try to save from Instruments. I'm using Instruments 15.3. Any ideas?

I'm working on this Mac Safari extension https://apps.apple.com/app/id6464076425 The installation of the app via Testflight stops without any success (only for me) As well as the installation via AppStore. This happens only to me. I tried it on another computer, and it installed successfully. Here are some videos: This makes the development and release process impossible until I solve this problem. I tried all the methods I could find online, such as: Deleting the currently installed app Restarting Safari Restarting my Mac Is there anything else I can do to fix this problem?

I'm currently supporting an app where one of the dependencies we use had an update. The app is an iPad only app that is meant to be run as a kiosk (guided access, single app mode). After the dependency update for the casing of the tablet / kiosk, we noticed an uptick in errors that may or may not have been associated with the recent 3rd party software update. I wanted to verify if the update had an impact on our production kiosks. To get a good idea of whether or not the update for casework's library had a negative impact, though, I would need to run instruments on a tablet while it's in the case. There's only one power cable to the iPad and the cable that would be used to connect directly to a Mac / Xcode is the same cable that connects to the casework. Is it possible to run instruments, and then retrieve data, from an app that's not directly connected to Xcode? Or is it possible for Xcode to somehow connect via a running instance of an app remotely?

I ran it (Leaks) on a process for about 2 hours. It collected 68gytes of data. It cannot open the folder -- can't find a file (which is there as a .zip archive) or if I expand it, just an error about missing an index. Filing a bug about this is difficult, since it's 68gbyets of data.

I'm on VisionOS 1.2 beta and Instruments will capture everything but RealityKit information. RealityKit frames and RealityKit metrics captures no data. This used to work though I'm not sure what version it did. Unbelievably frustrating.

Users have reported unusually high data usage with my app. So to investigate I have profiled in instruments. My app as expected in using minimal data. However in instruments I see an "Unknown" process. Which sends around 1mb of data every 2 seconds. Can anyone explain what unknown process is? Sorry my question is vague but I'm at the beginning of understanding the instruments outputs so your help is so very much appreciated.

Hi! I allready have started a product page optimization tests in the past, but now I want to test different versions of my icon. But I can't see the option to change the icons, how can I do that?

Hi! I watched WWDC 2019 Optimizing App Launch video and can't see the Lifecycle phases when I Profile my App. I'm using Xcode 15.2 with Instruments 15.2, and SwiftUI as UI framework. Here is a screenshot of what I get. It's there another tool or another way to get this information? Thanks! Alfonso.
