Description
I have a problem from this lib during running detox tests, simulators for react native works okay.

Screenshots
detox[17229] ERROR: [DetoxExportWrapper.js/DETOX_INIT_ERROR]
TypeError: Cannot read property 'identifier' of undefined
at AppleSimUtils.create (/.../node_modules/detox/src/devices/ios/AppleSimUtils.js: 100:100)

Environment

• macOS version: 10.14.5
• Xcode version: 10.3

Before Xcode update I didn't have this issue

If you run applesimutils --list, do you get a list of devices?

[redbluenat]

@LeoNatan yes, I have looooong list here is a part of it:

[LeoNatan]

OK, so this is a Detox issue. Moving.

[LeoNatan]

@redbluenat What version of applesimutils are you using?

[redbluenat]

@LeoNatan applesimutils version 0.7.0

[LeoNatan]

Very odd. I don't see a change in the output format from simctl, so applesimutils is exporting correctly.

[LeoNatan]

Can you post your Detox config from package.json?

[redbluenat]

"ios.sim.debug": {
"binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/app.app",
"build": "xcodebuild -workspace ios/app.xcworkspace -scheme app -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
"type": "ios.simulator",
"name": "iPhone Xs"
},

same issue

[LeoNatan]

@noomorph Any insights here? Thanks

[noomorph]

Of course, the insight is that detox.init has not been called. Currently, by.id functions are platorm-specific, and initiated inside detox.init. If it is important for you to have a very early access to them, post a feature request and we'll see what we can do.

[LeoNatan]

@noomorph Thanks! Could it also be that the init() somehow failed and that is causing this? Do you know what detox[13114] ERROR: [DetoxExportWrapper.js/DETOX_INIT_ERROR] is?

[noomorph]

Exactly, that's it. Init has failed.

[redbluenat]

I resolved this issue by updating Detox and

gem install xcode-install
xcversion simulators --install='iOS 12.4'

and add to configuration

 "name": "iPhone X, iOS 12.4"

I am still having this issue but only with threading. Particularly we are using --workers=3, though the # of workers, as long as its over 1, doesnt matter and will throw the error.

This is using jest and latest v of detox.

[WilGatlin]

Seems to be linked to this issue? https://github.com/wix/Detox/issues/1395

[WilGatlin]

Resolved by cleaning out all previous xcode and applesimutils. Reinstalling both with latest.
