EarlGrey: Running Xcode Generated UITest Crashes on eDistantObject`SetupBlockInvocationForward

Add EG2UITests UI Testing Bundle to our project
Add Pod file changes:

    pod 'EarlGreyApp' (added to app target definition)
    
    target 'EG2UITests' do
        pod 'EarlGreyTest'
        pod 'iOSSnapshotTestCase'
        test_pods
    end

Run pod install
Run (generated) UI Test
App crashes on launch:

@AlbertWang0116 I was able to get passed this error/crash 😅 . We have a rather complicated Podfile setup. To prevent duplicate linkage of static libraries, I added EarlGreyApp & EarlGreyTest to a list static frameworks passed toremove_static_framework_duplicate_linkage inside Podfile

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES'] = '$(inherited)'
        end
    end

    static_frameworks = [
      'EarlGreyApp',
      'EarlGreyTest'
    ]
    remove_static_framework_duplicate_linkage({
      'Framework' => static_frameworks
    })
end

remove_static_framework_duplicate_linkage as defined here

Albert, I checked the Podfile and eDistantObject version is 0.9.0.

Sorry for the latency. It is likely to be the dependency corruption at EarlGrey podspec. Could you check your Podfile.lock (auto generated beside your Podfile after pod install) that if the eDistantObject version is 0.9.1? If that’s the case, try changing it back to 0.9.0 and rerun the test (this was how I make Demo/EarlGreyExample work).

Downgrading to eDistantObject 0.9.0 as suggested in this seemingly similar issue did not work.
