Engine builders running Xcode 13 do not have any valid iOS simulator runtimes #94780
Description
Testing Xcode 13 cipd package in the engine shows no available iOS simulator runtimes.
Mac Web Engine (note no runtimes listed, and devices unavailable, runtime profile not found):
== Device Types ==
iPhone 4s (com.apple.CoreSimulator.SimDeviceType.iPhone-4s)
...
iPad mini (6th generation) (com.apple.CoreSimulator.SimDeviceType.iPad-mini-6th-generation)
== Runtimes ==
== Devices ==
-- Unavailable: com.apple.CoreSimulator.SimRuntime.iOS-13-0 --
iPhone 8 (19B472BA-C0FF-45EE-8CEF-9C6DDA134F18) (Shutdown) (unavailable, runtime profile not found)
iPhone 8 Plus (5828F22B-BA3B-443D-B554-76FD75C67AF4) (Shutdown) (unavailable, runtime profile not found)
iPhone 11 (DF95828D-5A62-4198-9214-67F1E3CE7A07) (Shutdown) (unavailable, runtime profile not found)
Mac Unopt IosUnitTests also cannot find available simulators even though it wants the "default" iOS 15 simulator -destination "platform=iOS Simulator,name=iPhone 11", which resolves to iOS 15 SDKROOT = iphonesimulator15.0, and iPhone 11. I see that device type is available in the downloaded cipd package at Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/DeviceTypes/iPhone 11.simdevicetype.
But the devicelab staging builders using the same Xcode cipd bundle shows only the iOS 15 runtime available, and module_test_ios test is passing on simulators.
Executing: xcrun simctl list runtimes in /opt/s/w/ir/x/w/recipe_cleanup/tmp742h195q/flutter sdk with environment {BOT: true, LANG: en_US.UTF-8}
== Runtimes ==
iOS 15.0 (15.0 - 19A339) - com.apple.CoreSimulator.SimRuntime.iOS-15-0
"xcrun" exit code: 0
and shows an available iOS 15, iPhone 11 simulator:
