Environment: Xcode 27.0 (27A266a), Mac App Store macOS 27.2 beta 1 (26B5086k) MacBook Pro M3 Max, 48 GB (Mac15,9) Xcode crashes 100% of the time the moment I start typing a new variable inside a struct in the source editor. Building, running and debugging all work fine — the crash only happens on keystroke in the editor. Crash log points to CoreML predictive code completion: EXC_BAD_ACCESS (SIGBUS) on thread MLSymbolPopularity.workQueue -> Espresso::inner_product_kernel_cpu::get_biases() -> CodeCompletionModel.init -> MLSymbolPopularity.loadModelIfNeeded So the Espresso/CoreML runtime in macOS 27.2 beta 1 crashes while loading the predictive-completion model. Tried, none fixed it: "Display code predictions" -> Never "Display code completions while typing" -> Manually defaults write com.apple.dt.Xcode IDEPredictiveCodeCompletionEnabled -bool NO Cleared DerivedData / Xcode caches Installed the full 2.25 GB model via Settings > Components (still crashes) Not in the beta 1 "Known Issues". Filed: FB24823899 (Core ML, with two .ips crash logs + repro steps). Anyone else seeing MLSymbolPopularity here?
