Reply to What are the *.symbols file in the ipa?
There's no information anywhere about this .symbols files and the information that they contain. Can they be used to symbolicate a crash (if DSYMs are not available)? what format do these files have? Using strings over a .symbols file, I can see that they do contain symbol names, but the file is not supported by any of the usual tools (dwarfdump, otool...)

Reply to Xcode 26 increase in dSYM size
Thank you for sharing your post. Please be advised that Xcode 26 is currently in beta testing. Could you please provide the beta and build number you are using, as well as the version of macOS you are running? To ensure the comprehensiveness of your report, please include the build number at which you initially encountered the issue, as well as any relevant screenshots, recordings, and dSYM file. Additionally, creating a test project can be a helpful way to demonstrate the issue to this problem. Before submitting a bug report, please provide additional information, including the nature of the project you are working on and any specific details that would be crucial for reproducing the issue. If you have a sample project showing this issue I can test with, please share. Do you get the same results with just the relevant code in a small test project? If so, please share a link to your test project. That'll help us better understand what's going on. If you're not familiar with preparing a test project,

Where is the download dSYM option in Testflight? Its not in Metadata
If I upload a build to Testflight using Xcode 14 that offers the option to upload the app symbols. Xcode 15 doesn't offer this option, so presumably it does so automatically. However I've got several builds in TF, built with both Xcode 14 and 15 but the option to download dSYMs isn't available in the Metadata section. There defiantly are dSYMs though - they are present in the archive. How can I download them for apps in Testflight and in the AppStore if the option isn't appearing in the Metadata section?

Reply to have .symbols files in Symbols folder but no .dSYM
Are you actually missing a dSYM in the .xcarchive, or are you saying that it's missing only in the .ipa you upload? Xcode won't include the dSYM in the upload when bitcode is enabled, because it has no use. The bitcode compilation process will create a new dSYM for you as a byproduct of any compilation, which you download later in the Xcode Organizer, and it is this new dSYM that helps you debug crashes coming in from customers who download your app from the App Store.

Reply to Symbolicating Crashes for Applications Submitted with Bitcode
My crash logs are also not symbolicating correctly. I am opted into bitcode and including symbols. System library symbols symbolicate fine, but symbols from my app do not. I was able to grab one of the crash logs directly off the device and I found that the UUID in that log doesn't match the UUIDs of the dsyms that are in my archive.I tried clicking the Download dsyms button in the Organizer window, but that gives me a response that no dsyms are available. However, if I go into iTunes connect, I can see that there are dsyms available for these builds, and I can even download them. Is there any way to get those manually downloaded dsyms into Xcode so I can resymbolicate the crash logs?

UUID of bitcode enabled app does not have dSYM available for download
I submitted MyApp with bitcode enabled app to TestFlight. I received a crash report where the binary UUID does match the UUIDs listed in the MyApp.app/MyApp or MyApp.app.dSYM that was built on my machine. I tried using the Download dSYMs... option in Xcode but still there is no dSYM downloaded that matches the UUID of the binary in the crash report. All other dSYMs are downloaded, however.Why isn't the dSYM for the binary that Apple built available?dwarfdump --uuid MyApp.app/MyAppUUID: 0BDA6D6F-3C0D-339E-842F-C2CB04199E10 (armv7) MyApp.app/MyAppUUID: B2A69BEC-DF5E-33EA-A9E0-490EBF03074C (arm64) MyApp.app/MyAppdwarfdump --uuid MyApp.app.dSYMUUID: 0BDA6D6F-3C0D-339E-842F-C2CB04199E10 (armv7) MyApp.app.dSYM/Contents/Resources/DWARF/MyAppUUID: B2A69BEC-DF5E-33EA-A9E0-490EBF03074C (arm64) MyApp.app.dSYM/Contents/Resources/DWARF/MyApp# Why is the the dSYM for this binary not being downloaded?0x100054000 - 0x1000fffff myapp arm64 <3715db2438743cf5aac1742d9a214c2c> /

Reply to Trying to symbolicate crash logs without dSym
Getting useful results from a crash log within a .dSYM is… well… tricky. You should be able to get the .dSYM you need from one of two places: If you submitted a native binary, you can use the .dSYM from the .xcarchive that you submitted from.If you submitted bitcode, you should be able to download the .dSYM from iTunes Connect.Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail = eskimo + 1 + @apple.com
