Expected Behavior

Run the UI test without problems in all simulators available.

Actual Behavior

The test is failing when the test runs on a iPhone 6S Plus simulator running iOS 11.4, it works normally for any device based on the iOS 13.x simulator. This is not happening when the UI test runs from Xcode, only using a external library like Fastlane.

Similar issue reported here: https://github.com/CocoaPods/CocoaPods/issues/9165 Already reported here with not enough information: https://github.com/airbnb/lottie-ios/issues/1109

EDIT 1: Also happening to iPad Pro (12.9-inch) (2nd generation) running iOS 11.4, so it's iOS version based.

Testing failed:

Anything similar to this? Add this line on podspec:

s.xcconfig = { 'ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES' => 'YES' }

We just noticed this as well. Same deal, it doesn't happen locally but only within the CI environment. Wondering if it may be some kind of Xcode simulator issue rather than Lottie/Fastlane.

You haven't found any work around have you?

Closing since this seems like its potentially either an outdated Xcode build system issue, or a configuration-specific issue. Feel free to re-open if you're still experiencing this issue.
