Host background port not assigned. Application under test may have failed to launch

[Sundea]

Xcode 11.5. iOS 13.5. iPhone Xs

I have installed EarlGrey 2.0 using Cocoapods. But it's doesn't work. When I started test run have an error "Host background port not assigned. Application under test may have failed to launch" And such strings in host app logs: dyld: warning: could not load inserted library '@executable_path/Frameworks/AppFramework.framework/AppFramework' into hardened process because no suitable image found. Did find: /private/var/containers/Bundle/Application/0C66B96A-8CB4-42F2-A1E7-43B7EABF3B08/Performance.app/Frameworks/AppFramework.framework/AppFramework: no matching architecture in universal wrapper /private/var/containers/Bundle/Application/0C66B96A-8CB4-42F2-A1E7-43B7EABF3B08/Performance.app/Frameworks/AppFramework.framework/AppFramework: no matching architecture in universal wrapper

Can you check DividePerformance.app bundle and make sure AppFramework is present there? Also can you paste the result of file command on these two binaries? I'd like to see what all architectures they're built. for:

file DividePerformance.app/DividePerformance and file DividePerformance.app/Frameworks/AppFramework.framework/AppFramework

For installing - has EarlGreyApp been added to the application process as well?

How I can check that AppFramework is present there?

You go into the BUILT_PRODUCTS_DIR folder where Xcode put the final artifact, cd into it and run the two commands.

It was added as a pod to proper target.

no matching architecture in universal wrapper are you running this on a device with architecture armv7e or so?

The device is iPhone XS, arm64e as I know

[tirodkar]

Correction - yes I meant arm64e. In the current CocoaPods release for EG 2, we haven't added arm64e. This will be fixed in the next CocoaPods EarlGrey 2.0 release which will happen soon.
