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.

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 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.

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?

Hi! Is there a reason why trace's *-profile tables (time-profile, cpu-profile, counters-profile) always use an instruction pointer value that is 1 byte larger than what should be a true instruction pointer value? Odd valued IPs on Apple M2 are definitely incorrect as instructions have to be word-aligned. It's also worth mentioning that addresses in "source" tables ("time-sample" for "time-profile", "kdebug-counters-with-pmi-sample" for "cpu-profile" and "counters-profile") are correct (or, at least, are correctly aligned aligned). Here's an example: % xctrace version xctrace version 15.2 (15C500b) # run recording % xctrace record --template "Time Profile" --output TP.trace --launch /bin/dd if=/dev/random of=/dev/null bs=1024 count=1048576 # extract "source" table % xctrace export --input TP.trace --xpath='/trace-toc/run[1]/data/table[@schema="time-sample"]' > tp.time-sample.xml # extract "derived" table % xctrace export --input TP.trace --xpath='/trace-toc/run[1]/data/table[@schema="time-profile"]' > tp.time-profile.xml % xmllint --xpath '//row[1]' tp.time-sample.xml <row><sample-time id="1" fmt="00:00.040.502">40502000</sample-time><thread id="2" fmt="Main Thread 0x37c2d0a (dd, pid: 32471)"><tid id="3" fmt="0x37c2d0a">58469642</tid><process id="4" fmt="dd (32471)"><pid id="5" fmt="32471">32471</pid><device-session id="6" fmt="TODO">TODO</device-session></process></thread><core id="7" fmt="CPU 4 (P Core)">4</core><thread-state id="8" fmt="Running">Running</thread-state><sentinel/><kperf-bt id="9" fmt="PC:0x1863149fc, 3 frames, 1 regs, pid: 32471"><text-addresses id="10" fmt="frag 1717">6546645708 6546360308 0</text-addresses><text-address id="11" fmt="0x1863149fc">6546344444</text-address><process ref="4"/><register-content id="12" fmt="0x2e4c00018635e2cc">3336041430521340620</register-content></kperf-bt><time-sample-kind id="13" fmt="Timer Fired">0</time-sample-kind></row> % xmllint --xpath '//row[1]' tp.time-profile.xml <row><sample-time id="1" fmt="00:00.040.502">40502000</sample-time><thread id="2" fmt="Main Thread 0x37c2d0a (dd, pid: 32471)"><tid id="3" fmt="0x37c2d0a">58469642</tid><process id="4" fmt="dd (32471)"><pid id="5" fmt="32471">32471</pid><device-session id="6" fmt="TODO">TODO</device-session></process></thread><process ref="4"/><core id="7" fmt="CPU 4 (P Core)">4</core><thread-state id="8" fmt="Running">Running</thread-state><weight id="9" fmt="1.00 ms">1000000</weight><backtrace id="10"><frame id="11" name="0x1863149fd" addr="0x1863149fd"><binary id="12" name="dyld" UUID="324E4AD9-E01F-3183-B09F-3E20B326643A" arch="arm64e" load-addr="0x186313000" path="/usr/lib/dyld"/></frame><frame id="13" name="0x18635e2cc" addr="0x18635e2cc"><binary ref="12"/></frame><frame id="14" name="start" addr="0x1863187f4"><binary ref="12"/></frame></backtrace></row> As you can see, <kperf-bt id="9" fmt="PC:0x1863149fc, 3 frames, 1 regs, pid: 32471"> refers to a properly aligned address, but the address from <backtrace id="10"><frame id="11" name="0x1863149fd" addr="0x1863149fd">... is off by one. It seems like only an address from the top frame is incorrect, as others are aligned properly. The same issue exists for "CPU Profile" and "CPU Counters" instruments and could be reproduced on macOs running on both x86-64 and Apple-Silicon CPUs.

I have an iOS app that uses os_signpost API for instrumentation. When I profile it from Xcode on real iOS device, it works as expected. When I profile its macCatalyst variant (using the identical code) on the same Mac where Xcode is running, the os_signpost Instrument does not show anything, not even the Apple provided signposts that are otherwise visible on the iOS. How do I make it work?

The Points of Interest Instrument is not recording any data when profiling my application on Sonoma. The same code is producing signposts when profiling on a computer running Sonoma. Here's what how the instruments screen looks: Note that there are no Points of Interest being recorded. I created a new project for this test and added code to emit signposts whenever the application becomes active or goes into the background. This is the code I'm using for the test (copied from forum post from a year ago). import os.signpost @main class AppDelegate: NSObject, NSApplicationDelegate { var window: NSWindow? var blackWindow: NSWindow? var alertWindow: NSWindow? static var originalAppDelegate: AppDelegate! var signposter: OSSignposter var signpostInterval: OSSignpostIntervalState? func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool { return true } override init() { signposter = OSSignposter(subsystem: Bundle.main.bundleIdentifier ?? "unknown", category: .pointsOfInterest) super.init() assert(signposter.isEnabled) signposter.emitEvent(#function) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } func applicationWillResignActive(_ notifiction: Notification) { guard let interval = signpostInterval else { assertionFailure("no interval") return } print("backgrounding, ending active state") signposter.endInterval("active", interval) } func applicationDidBecomeActive(_ notification: Notification) { print("begin active state") signpostInterval = signposter.beginInterval("active") } } Is anyone else having this problem? I tested this on my development machine (Retina 5K, 27-inch, 2019) running Sonoma 14.2.1. The problem occurs even with a clean install of Sonoma onto an external boot disk. The same code produces this screenshot when running in Ventura 13.6.1.

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?

Instruments in XCode 14 used to support CPU counters in A16 with iOS 16.x, but after I upgrade iOS to 17.1 and also XCode to 15.0.1, In "CPU Counters", it says "CPU Name: Unsupported" and thus I cannot choose "Sample by" events etc. Found some link on this:https://stackoverflow.com/questions/77344529/is-latest-instruments-not-support-a17-pro-for-cpu-counters Please help to confirm this is some known issue, and if so, how to fix it. Thanks!

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, Machine: M1 sonoma 14.1.1 At my test I am using macOS shipped lib of curl, and its default LibreSSL, that is: curl 8.1.2 (x86_64-apple-darwin23.0) libcurl/8.1.2 (SecureTransport) LibreSSL/3.3.6 zlib/1.2.12 nghttp2/1.55.1 I am getting memory leaks while running the following test: void CallCurl() { CURL *hnd; hnd = curl_easy_init(); curl_easy_setopt(hnd, CURLOPT_URL, "https://www.google.com"); curl_easy_perform(hnd); curl_easy_cleanup(hnd); } I track the leaks with macOS instruments, and I see that all leaks are from libcrypto. The leaks are measured after curl_easy_cleanup.

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.

I am trying to profile my app for 'Data Persistence', but I am not getting any data in the Instruments. I tried restarting Xcode and Mac, still no progress. It is showing blank graph for faults, fetches and saves

I am interested in adding signposts to an existing large application that was written in .NET compiled in VisualStudio for MacOS so that I can isolate portions of the application in instruments. It seems like it's straightforward to do this in C++ but I couldn't figure out how to do it, perhaps there is a way via dll invoke? Appreciate any suggestions.
