I’ve been seeing similar repeated crashes when opening, closing, or simply running Simulator since using the earlier betas and continuing even now with stable releases. Environment: Apple-silicon Mac (Mac17,9), macOS 27.0.1 (26A434), Xcode 27 / iOS 27 simulator runtime. Crashing services: intelligencetasksd AppIntentsLiveEntityService SettingsSearchReindexService others All three are simulator processes (launchd_sim parent) and crash with EXC_BREAKPOINT / SIGTRAP, following the same stack: XPCPeerRequirement.hasEntitlement(_:) → __XPC_API_MISUSE__ → __XPC_INTERNAL_CRASH__ → _assertionFailure Reboots, Xcode updates, reinstalling the simulator runtime, creating fresh simulators, and clearing simulator caches/DerivedData haven’t resolved it. Has anyone identified a cause or workaround for this stuff?

Same here. We are trying to test/debug a critical feature involving network (which obviously needs to be tested on losing/reconnecting wifi) and it is–as of now, writing this post–impossibile: even when launching with the device attached to USB the debugger crashes as soon as wifi is disabled. Honestly a little concerning that this was overlooked.
