Bundle.main.path always return nil in ios

In the project, created from cordova with added plugin (like in this tutorial https://moduscreate.com/blog/writing-a-cordova-plugin-in-swift-for-ios/)  we are not able to access to bundle's resources.

Bundle.main.path(forResource: "CDVLaunchScreen", ofType: "storyboard") or any kind of other resources always return nil.
