Reply to dyld crash before main() on macOS Tahoe 26 due to shared cache mapping failure
Thank you very much for the quick response and for the suggested next steps. I tested my demo project on macOS 27 beta + Xcode 27 beta 4 + iOS 27 Simulator runtime. The good news is that dyld no longer crashes in DyldSharedCache::getUUID() after the simulated shared-cache initialization failure. However, in my demo project, dyld still terminates but at a different point during its initialization before reaching main(). crash.ips.txt I’m not sure how to interpret this result. Since my demo project is intended to model our production scenario, I don’t know whether this change means that the underlying issue has been resolved or whether my demo is now simply reaching a different termination point inside dyld. At this point I’m not sure how best to proceed. Would you recommend that I continue investigating this new behavior, wait for future beta updates, or would you suggest something else?
