Hi,

I’m encountering a consistent boot failure on iOS 27.3 simulator runtime with the new DeviceHub architecture in the latest Xcode.

Environment
  • Mac: Apple Silicon
  • macOS version: [macOS Golden Gate 27.2]
  • Xcode version: [27.2]
  • Runtime: iOS 27.3 Simulator Runtime
  • Architecture: DeviceHub (new CoreDevice stack, no old CoreSimulatorService fallback)
