I’m seeing a reproducible iPhone Duo Simulator boot failure in Xcode 27.1. Environment Xcode 27.1 / 27A9275 macOS Tahoe 26.6.2, then 26.7.1 Apple silicon Mac iPhone Duo / V68 / iPhone19,4 iOS 27.1 Simulator Runtime builds 24A94232 and 24A94425 Failure Running: xcrun simctl bootstatus -b terminates with: Status=3, isTerminal=YES Data Migration Failed Fresh Duo devices reproduced the failure on both runtime builds. During fresh migrations, DataMigrator logged: Reporting migration failure due to migration progress window incident On one fresh-device run, all 35 recorded migration plugins completed successfully, but the aggregate migration result was false and no failed-plugin identifier was exposed. I also tested: brand-new Duo simulator data restarting the correct CoreSimulatorService explicitly selecting runtime 24A94425 updating macOS from 26.6.2 to 26.7.1 An ordinary iPhone simulator on iOS 27.0 works on the same Mac. The failure occurs before any application is installed or launched. Feedback filed: FB25221101 Has anyone else seen this with the iPhone Duo Simulator in Xcode 27.1?
