Hey everyone 👋
I'm starting to see this on all my repos on Github Actions, including Arrow. Invalid device: Apple Watch Series 5 - 44mm
8405
Any ideas how to fix this? It's been blocking a couple projects, and I've tried a couple things but none seems to work. If I check the MacOs runner to list the simulators it lists this specific simulator, and it's amongst the list 🤔

You'll either need to add a new simulator in CI with the likes of xcrun simctl create $foo $bar or you can force the simulator to be used by Kotlin with

tasks.withType<KotlinNativeSimulatorTest> {
    deviceId = "$foo"
}

[mbonnin]

I remember something about 44mm vs (44mm) or something like this

[mbonnin]

The string has to match exactly IIRC

[simon.vergauwen]

I saw your message when browsing Slack but I couldn't figure out how to use KotlinNativeSimulatorTest since it only seems to fail for watch 🤔 Can you run the watch tests on an iPhone?

I tried xcrun simctl create but I got a message that the device already existed :s

[mbonnin]

This is what I did to "fix" it on my local machine

xcrun simctl create "Apple Watch Series 5 - 44mm" "Apple Watch Series 5 (44mm)"

[simon.vergauwen]

Okay, going to try that command on CI.

[mbonnin]

Can you run the watch tests on an iPhone?

Yea, good call, I think not. I guess it then has to check the name or something like this

[mbonnin]

tasks.withType<KotlinNativeSimulatorTest> {
    when (name) {
       "watchosSimulatorArm64Test" -> deviceId = "Apple Watch Series 5 (44mm)"
    }
}

Not great but should work

FYI this should be fixed in 1.8.0-Beta, where test devices are picked from the list of available devices: https://youtrack.jetbrains.com/issue/KT-54090/Take-an-Apple-test-device-from-the-device-list

[simon.vergauwen]

Oh nice! Happy to hear that! Hopefully it can progress from the beta soon 🤞

You can also downgrade Xcode

[simon.vergauwen]

@jw so Github Action started failing because they upgraded XCode in the runners? 🤕

[Rick Clephas]

@simon.vergauwen they indeed made Xcode 14 the default recently

[simon.vergauwen]

Aha, okay. That explains a lot.

I solved the issue by using the recommendation from @mbonnin in Arrow.

xcrun simctl create "Apple Watch Series 5 - 44mm" "Apple Watch Series 5 (44mm)"

Downgrading XCode in Github Actions sound tedious, so I'll Martin's fix until 1.8.0 is released. Thanks for all the help 🙏

It's a three-line change
