@swift-ci please test

That’s fine. That being said, if windows testing clean effectively blocks commits, then it should be required before merging, right? CC: @shahmishal

@davezarzycki There's also an iOS failure in Build #20863 (using "test" instead of "smoke test").

FAIL: Swift(iphonesimulator-i386) :: IRGen/class_resilience.swift (11888 of 13208)

Hi @benrimmington – I'm struggling to reproduce the 32-bit error. How are people supposed to run the 32-bit simulator these days? Does that require a copy of macOS earlier than Catalina?

[benrimmington]

@davezarzycki I haven't tried recently, but it used to require a 32-bit iOS simulator with a specific name (e.g. "iPhone 5"). I'm trying it now to see what the actual name should be.

The last 32-bit device was the iPhone 5, which supports up to iOS 10.3.4; and the oldest simulator available to download (in the latest Xcode + macOS) is "iOS 10.3.1 Simulator".

Right. I get bunch of “Invalid device: iPhone 5” errors and xcrun simctl list doesn’t list iPhone 5 as a valid device for 10.3 despite the fact that it should be there. I’d wager that macOS Catalina effectively cut off 32-bit simulators from working

I've created #31866 to update the Testing.md document.
