'InitialSceneType' requires that 'StoryboardScene.UILoadingViewController' inherit from 'UIViewController'

[gerchicov-vg]

generated:

internal enum UILoadingViewController: StoryboardType {
    internal static let storyboardName = "UILoadingViewController"

    internal static let initialScene = InitialSceneType<UILoadingViewController>(storyboard: Self.self)
  }

expected and workable:

internal enum UILoadingViewController: StoryboardType {
    internal static let storyboardName = "UILoadingViewController"

    internal static let initialScene = InitialSceneType<ProjectName.UILoadingViewController>(storyboard: Self.self)
  }

the only difference is UILoadingViewController vs ProjectName.UILoadingViewController. How to fix it properly?
