After switching from Xcode 16 to Xcode 26, the app crashes. It runs normally in Xcode 16 but crashes in Xcode 26. The stack trace is below.

dyld[29371]: Library not loaded: /usr/lib/swift/libLiveExecutionResultsLogger.dylib Referenced from: <C9F5CC11-0C22-3439-B81C-255911E51CF9> /private/var/containers/Bundle/Application/306FCC79-E84A-4C54-ACBE-D1EC6A469560/BoxPlayer.app/BoxPlayer.debug.dylib Reason: tried: '/usr/lib/system/introspection/libLiveExecutionResultsLogger.dylib' (no such file, not in dyld cache), '/usr/lib/swift/libLiveExecutionResultsLogger.dylib' (no such file), '/private/preboot/Cryptexes/OS/usr/lib/swift/libLiveExecutionResultsLogger.dylib' (no such file), '/usr/lib/swift/libLiveExecutionResultsLogger.dylib' (no such file, not in dyld cache)

Same here. It seems to occur if I use import Playgrounds and the #Playground macro in a SPM module. So far I haven't found a workaround. Just don't use the playground macro.

(Side note: Why do I feel that it happens all the time that features are made for WWDC presentations, but do not work at all in reality, and fail in the most basic setups? I came to the platform, because it didn't use to be that way…)

@Gernot Do you have a crash file or better yet a focused sample that reproduces that issue?

Focused Sample:

That'll help us better understand what's going on. If you're not familiar with preparing a test project, take a look at Creating a test project.
