Xcode 16 warning about missing symbols of static framework
I work on an SDK, and one of the ways we distribute it is as a pre-compiled static XCFramework. As far as I know, it’s the nature of a static framework to not contain symbols since the framework will be embedded in the final app binary, and the symbols should then be generated. However, when testing the "Validate" function of the Xcode 16 deployment process, our users are receiving a warning that says the framework does not contain symbols. Is my assumption about static frameworks and symbols incorrect? Could this be a bug in Xcode 16? Should we modify something in our framework to inform Xcode that symbols are not needed?

Posting a Crash Report
If you need help investigating a crash, please include a crash report in your post. To smooth things along, follow these guidelines: For information on how to get a crash report, see Acquiring crash reports and diagnostic logs. Include the whole crash report as a text attachment (click the paperclip icon and then choose Add File). This avoids clogging up the timeline while also preserving the wealth of information in the crash report. If you’re not able to post your crash report as an attachment, see Can’t Post Crash Report as Attachment below. If you want to highlight a section of the report, include it in the main body of your post. Put the snippet in a code block so that it renders nicely. To create a code block, add a delimiter line containing triple backquotes before and after the block, or just click the Code Block button. If possible, post an Apple crash report. Third-party crash reporters are often missing critical information and have general reliability problems (for an explanation as to why, see Implementing Your Own Crash Reporter). Symbolicate your crash report before posting it. For information on how to do this, see Adding identifiable symbol names to a crash report. If you need to redact the crash report, do so consistently. Imagine you’re building the WaffleVarnish app whose bundle ID is com.example.wafflevarnish but you want to keep your new waffle varnishing technology secret. Replace WaffleVarnish with WwwwwwVvvvvvv and com.example.wafflevarnish with com.eeeeeee.wwwwwwvvvvvvv. This keeps the text in the crash report aligned while making it possible to distinguish the human-readible name of the app (WaffleVarnish) from the bundle ID (com.example.wafflevarnish). Finally, for information on how to use a crash report to debug your own problems, see Diagnosing issues using crash reports and device logs. Can’t Post Crash Report as Attachment Crash reports have two common extensions: .crash and .ips. If you have an .ips file, please post that [1]. DevForums lets you attach a .crash file but not an .ips file (r. 117468172). To work around this, change the extension to .txt. If DevForums complains that your crash report “contains sensitive language”, leave it out of your initial post and attach it to a reply. That often avoids this roadblock. If you still can’t post your crash report, upload it to a file sharing service and include the URL in your post. Post the URL in the clear, per tip 14 in Quinn’s Top Ten DevForums Tips. Getting a Crash Report from the Xcode Organiser The Xcode organiser shows crash reports from customers. If you’re investigating such a crash and want to post a crash report: Navigate to the crash in the Xcode organiser. Note If you can’t see the right crash, check the filter popups at the top. In the list of crashes, secondary click on your crash and choose Show in Finder. That reveals the Xcode crashpoint document (.xccrashpoint) in the Finder. Secondary click on that and choose Show Package Contents. In the resulting Finder window, find a crash report (.crash) that accurately represents the crash you’re investigating and attach that to your forums post. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" [1] Because it’s easy to go from an .ips file to a .crash file. I usually do this by choosing File > Quick Look in the Finder. For more info about these file formats, see this post. Revision History: 2025-08-29 Added the Getting a Crash Report from the Xcode Organiser section. 2024-11-21 Added a recommendation to post the .ips format if possible. 2024-05-21 Added some advice regarding the “contains sensitive language” message. 2023-10-25 Added the Can’t Post Crash Report as Attachment section. Made other minor editorial changes. 2021-08-26 First posted.

Canvas keeps resizing to 50/50 width in Xcode
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:

Files app in iOS 18 beta simulator is read-only
The Files app in the iOS 18 beta simulator appears to be read-only. I am unable to: create folders copy files into it by dragging them from macOS safe files from safari I have been unsuccessful at finding a way to popular any file or folder in the Files app which is preventing me from testing some scenarios in my app where I import files using the files sheet. The earliest I tried was beta 3 and it still persists in beta 7. The iOS 17 simulator works fine in comparison. My mac is a 2019 macbook pro running Sonoma 14.5. To reproduce: New folder Launch Files app in iOS simulator Tap into "On my phone" From the top menu tap "New Folder" (nothing happens) Download a file Launch safari Find a file like a PDF to download Tap on the down arrow in the toolbar Files opens up with the filename in the textfield at the bottom The "Save" button is grayed out. Copy from macOS Open the Files app in iOS and browse to a local folder drag a file from the macbook onto the simulator the sheet appears with the filename in the text field The "Save" button is grayed out

Error reporting test coverage in Xcode 14.3.1

Predictive code completion is not working for existing project.
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.

Xcode 16 | xcodebuild fails when providing -destination 'platform=iOS Simulator,name=iPhone 16,arch=x86_64'
Hello. In the Xcode 15 we were using this command in the terminal to run our tests on the Rosetta Simulator: xcodebuild -workspace CoreLibraries.xcworkspace -scheme CoreLibraries -destination 'platform=iOS Simulator,name=iPhone 15,arch=x86_64' test` In the Xcode 16 the same command doesn't work anymore. It produces the error: xcodebuild: error: Unable to find a device matching the provided destination specifier: { platform:iOS Simulator, arch:x86_64, OS:latest, name:iPhone 16 } Unsupported device specifier option. The device “iPhone 16” does not support the following options: arch Please supply only supported device specifier options. Running test directly from the Xcode UI using iPhone 16 (Rosetta) still works fine. Does anyone know how to modify the xcodebuild command to make it work again?

Standard Memory Debugging Tools
In many cases I’ll be talking to folks with a memory management problem and I’ll say “You should investigate this with the standard memory debugging tools.” They then turn around and ask me “What are those tools?” Well, this is what I mean: Zombies — This lets you quickly detect when an object is used after it’s been deallocated. Learn more about it in the Finding zombies section of the Instruments Help and in Investigating crashes for zombie objects. There was also an excellent WWDC video about this, namely, WWDC 2010 Session 311 Advanced Memory Analysis with Instruments. This is no longer available in the video archive but if you can find a copy it’s well worth a watch. Address Sanitizer — This is a lower-level tool that finds a variety of common memory management issues, including use after free and buffer overruns. Learn more about this in Diagnosing memory, thread, and crash issues early and the various articles it links to. There’s also a good discussion of this tool, and other Xcode runtime diagnostic tools, in WWDC 2017 Session 406 Finding Bugs Using Xcode Runtime Tools (also no longer available from Apple). Hardware memory tagging — If you have access to a device with hardware memory tagging — starting with the A19 or M5 processors — consider enabling Memory Integrity Enforcement (MIE). For the details, see Enabling enhanced security for your app or watch Secure your app with Memory Integrity Enforcement. Even if you don’t want to do that for your production app, enable it just for development by checking Hardware Memory Tagging in the Options tab of Xcode’s scheme editor. Older tools — There are a variety of older tools that might be useful in some specific circumstances. See the Enabling the Malloc Debugging Features section of the Memory Usage Performance Guidelines for more information about these. Of specific interest is libgmalloc, which is documented in a UNIX man page. For some practical examples of how to identity a memory management crash report and then investigate that crash with these tools, take a look at WWDC 2018 Session 414 Understanding Crashes and Crash Logs. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Revision History: 2026-03-02 Added a discussion of hardware memory tagging. 2023-05-09 Added a link to Investigating crashes for zombie objects. 2023-03-22 Removed another WWDC session video link. Made minor editorial changes. 2020-10-23 Fixed some formatting errors. 2019-10-30 Removed the link to WWDC 2010 Session 311 Advanced Memory Analysis with Instruments because it’s not long available in the archive. Refreshed all the other links. 2019-01-22 Fixed the link to libgmalloc. 2018-11-02 Updated to include a reference to WWDC 2018 Session 414 Understanding Crashes and Crash Logs. 2017-11-16 First posted.

-Xlinker -reproducible flag breaks debug symbols for static library which object files has same name
Hi! For example i have library with structure like ModuleA/test.cpp, ModuleB/test.cpp, then i build it like: #Building library clang++ -c ModuleA/test.cpp -o ModuleA/test.o clang++ -c ModuleB/test.cpp -o ModuleB/test.o libtool -o module.a ModuleA/test.o ModuleB/test.o #Now reproducing build steps from Xcode #Compiling... clang++ -c main.cpp -o main.o #Linking... clang++ -Xlinker -reproducible -o main main.o module.a Now if we launch lldb main, we cant set breakpoint in file ModuleB/test.cpp, only in ModuleA/test.cpp, if link without -Xlinker -reproducible, both breakpoints working as expected. Also dsymutil completely delete symbols for "duplicate" library if link with reproducible flag. It's just example, in real static library i can't change behavior of building process, and can't change names of producing object files. Xcode always set -Xlinker -reproducible flag, and i don't know how to disable it, and my debugging process partially broken. ENV: macos: 15.4.1 Xcode: 16.2

Xcode 15 not finding iOS 17 devices
I have a brand new iPhone 15 with iOS 17, paired with a watch on WatchOS10. In devices and simulators, the iPhone 15 and Watch 10 device show up as disconnected (with the globe icon I think is what it is?) and if I click on either of them, that icon changes to a spinner, and the main window says "Xcode will continue when the operation completes", but it NEVER completes. This makes the device not usable for development. In addition, I have updated my iPad to iOS17, and it doesn't even show up at all in the devices and simulator list, even though it is enabled for developer mode. I have toggled developer mode off and on (thus rebooting). I have quit and restarted Xcode. I have even rebooted the Mac. Nothing helps. This is incredibly frustrating.

TestFlight version of Mac Multiplatform is on the wrong AppStore, but not the iOS TestFlight build
Hello, I'm sure I've probably missed a checkbox somewhere.. I have a mulitiplatform app, when building from Xcode, and not using the testing config, both iOS and macOS show the correct App Store currency.. When I distribute a build through TestFlight, my Mac version shows a different country/currency price (the US one). I can't find anywhere to change this. My Mac is signed into the same sandbox account as my iOS device. Can anyone help?

[Help] Xcode device debugging of iOS 18.4 / 18.5 is very slow, and it is suspected to be stuck in the stage of loading dynamic libraries in debugserver
Environment Xcode version: Xcode 16.0 iOS device system version: iOS 18.4 / 18.5 Problem description When debugging iOS 18.4/18.5 on a real device, the App starts very slowly after clicking Run, usually taking 2-3 minutes, which is much slower than iOS 18.3. It manifests as Xcode staying in the Launch stage for a long time, and the application stuck in the opening screen interface. Start the APP first, then attach the process, and this problem will not exist Location process Use lldb to enable logs log enable gdb-remote packets After observing the logs, it was found that: The jam mainly occurs when processing two data packets: jGetLoadedDynamicLibrariesInfos and qProcessInfo These two commands involve dynamic library loading information and process meta information, and the response time is much higher than the normal level, far exceeding other gdb-remote instructions Use Instruments / Profiler to analyze: The CPU peak of the real machine debugserver is concentrated in the dynamic library information loading process of _dyld_process_info_create Is there a way to deploy a modified debugserver on the real machine to further locate the problem How to enable and view the debugsever log to further locate the problem

There’s also a good discussion of this tool, and other Xcode runtime diagnostic tools, in WWDC 2017 Session 406 Finding Bugs Using Xcode Runtime Tools (also no longer available from Apple). Hardware memory tagging — If you have access to a device with hardware memory tagging — starting with the A19 or M5 processors — consider enabling Memory Integrity Enforcement (MIE). For the details, see Enabling enhanced security for your app or watch Secure your app with Memory Integrity Enforcement. Even if you don’t want to do that for your production app, enable it just for development by checking Hardware Memory Tagging in the Options tab of Xcode’s scheme editor. Older tools — There are a variety of older tools that might be useful in some specific circumstances. See the Enabling the Malloc Debugging Features section of the Memory Usage Performance Guidelines for more information about these. Of specific interest is libgmalloc, which is documented in a UNIX man page. For some practical examples of how to identity a memory management crash report and then investigate that crash with these tools, take a look at WWDC 2018 Session 414 Understanding Crashes and Crash Logs.

Duplicate apps launched when debugging in Xcode?
I’ve noticed a strange bug in Xcode 16 and Swift. When a preview is rendering and hasn’t finished yet and you run an app to debug, Xcode is launching two instances of the app. Has anyone else noticed this issue? If you let the preview finish rendering before running the app, this doesn’t happen. Very odd.

-Xlinker -reproducible flag breaks debug symbols for static library which object files has same name
Hi! For example i have library with structure like ModuleA/test.cpp, ModuleB/test.cpp, then i build it like: #Building library clang++ -c ModuleA/test.cpp -o ModuleA/test.o clang++ -c ModuleB/test.cpp -o ModuleB/test.o libtool -o module.a ModuleA/test.o ModuleB/test.o #Now reproducing build steps from Xcode #Compiling... clang++ -c main.cpp -o main.o #Linking... clang++ -Xlinker -reproducible -o main main.o module.a Now if we launch lldb main, we cant set breakpoint in file ModuleB/test.cpp, only in ModuleA/test.cpp, if link without -Xlinker -reproducible, both breakpoints working as expected. Also dsymutil completely delete symbols for "duplicate" library if link with reproducible flag. It's just example, in real static library i can't change behavior of building process, and can't change names of producing object files. Xcode always set -Xlinker -reproducible flag, and i don't know how to disable it, and my debugging process partially broken. ENV: macos: 15.4.1 Xcode: 16.2

Xcode 15 not finding iOS 17 devices
I have a brand new iPhone 15 with iOS 17, paired with a watch on WatchOS10. In devices and simulators, the iPhone 15 and Watch 10 device show up as disconnected (with the globe icon I think is what it is?) and if I click on either of them, that icon changes to a spinner, and the main window says "Xcode will continue when the operation completes", but it NEVER completes. This makes the device not usable for development. In addition, I have updated my iPad to iOS17, and it doesn't even show up at all in the devices and simulator list, even though it is enabled for developer mode. I have toggled developer mode off and on (thus rebooting). I have quit and restarted Xcode. I have even rebooted the Mac. Nothing helps. This is incredibly frustrating.

TestFlight version of Mac Multiplatform is on the wrong AppStore, but not the iOS TestFlight build
Hello, I'm sure I've probably missed a checkbox somewhere.. I have a mulitiplatform app, when building from Xcode, and not using the testing config, both iOS and macOS show the correct App Store currency.. When I distribute a build through TestFlight, my Mac version shows a different country/currency price (the US one). I can't find anywhere to change this. My Mac is signed into the same sandbox account as my iOS device. Can anyone help?

[Help] Xcode device debugging of iOS 18.4 / 18.5 is very slow, and it is suspected to be stuck in the stage of loading dynamic libraries in debugserver
Environment Xcode version: Xcode 16.0 iOS device system version: iOS 18.4 / 18.5 Problem description When debugging iOS 18.4/18.5 on a real device, the App starts very slowly after clicking Run, usually taking 2-3 minutes, which is much slower than iOS 18.3. It manifests as Xcode staying in the Launch stage for a long time, and the application stuck in the opening screen interface. Start the APP first, then attach the process, and this problem will not exist Location process Use lldb to enable logs log enable gdb-remote packets After observing the logs, it was found that: The jam mainly occurs when processing two data packets: jGetLoadedDynamicLibrariesInfos and qProcessInfo These two commands involve dynamic library loading information and process meta information, and the response time is much higher than the normal level, far exceeding other gdb-remote instructions Use Instruments / Profiler to analyze: The CPU peak of the real machine debugserver is concentrated in the dynamic library information loading process of _dyld_process_info_create Is there a way to deploy a modified debugserver on the real machine to further locate the problem How to enable and view the debugsever log to further locate the problem
