“Xcode”

Based on the above I tried reproducing this with a test project. And lo! it’s trivial to reproduce: I started with Xcode 26.3 without the Metal Toolchain 26.3 component installed. I created a new project from the iOS > App template. In the General tab of the target editor, I removed the Mac (Designed for iPad) destination. And added the Mac (Mac Catalyst) destination. I selected My Mac (Mac Catalyst) as the run destination. I chose Product > Build; the project built without any warning. In Xcode > Settings > Components, I installed the Metal Toolchain 26.3 component. I chose Product > Clean. And then Product > Build. I now see a build warning: ld: warning: search path '/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.7003.10.hJke6J/Metal.xctoolchain/usr/lib/swift/maccatalyst' not found Given the above, I can only conclude that this is a bug. I did some digging and was unable to find any more backstory (for example, I thought that someone m

Cool. I consider this to be a problem with Xcode’s build system, but it’s an understandable one. Xcode knows that your tool depends on this library — because it adds an import of it — but, being a command-line tool, it doesn’t have anywhere to embed the library. It should embed it in the container app, but it’s clearly not doing that. I think it’s worth filing a bug against Xcode about that. And if you do, please post your bug number, just for the record. As to a workaround, there’s a couple of ways to approach that. The first is the obvious one we’ve been discussing here: Add a dummy use of Subprocess within your app. Xcode will embed libswiftCompatibilitySpan.dylib, because it knows that your app needs it, and your tool can pick it up from there The other option is to embed the library explicitly. This is complicated by the fact that the library exists within a toolchain, so it’s not clear how to reference it [1]. For the moment I recommend that you go with the first opti

Developer ID signing has been required for a long time (10.8?). Notarisation for apps has been required since 10.14. [quote='818269021, anonymousdev332299, /thread/818269, /profile/anonymousdev332299'] Is [ditto] necessary to properly preserve the app bundle structure and extended attributes? [/quote] Yes and no. If you compress with the Finder then extended attributes get sequestered, which is not good. See Extended Attributes and Zip Archives. The ditto tool doesn’t do that by default. However, in an ideal world this wouldn’t matter because your code signature should not depend on extended attributes. If you find that it does, that suggests your have a bundle structure problem. We talk about this more in TN3126 Inside Code Signing: Hashes and Placing content in a bundle. As to what’s actually happening here, it’s hard

I have the same problem with Xcode 26.3 and Xcode 26.4 (Beta 3).

Also have problem with git fetch from Xcode, in terminal all work good.

Thanks Ed, this did work. The confusion for me comes from the output & results of the downloadPlatform command above - the export file is automatically named iphonesimulator_26.1_23B86.dmg, and there's no mention in the output that the SDK Platform Support (ver 23B77) component has also been exported. There also wasn't anything in the output when running importPlatform to indicate that this component was being imported, however it did show up correctly in Xcode afterwards when viewing Settings -> Components. Perhaps some indication in the output from both of these commands that the platform support component is included would avoid this confusion?

Xcode Cloud has the Metal toolchain ready for use without any additional installation required. If you remove these commands from your ci_pre_xcodebuild.sh script, does your build succeed? — Ed Ford,  DTS Engineer
