I've been going the other direction recently. We have a photoshop plugin that exports layers with metadata (where an image is located, fonts, font sizes, text, etc). For any platform that has a basic scene graph and some sort of label functionality (Unity, iOS, android, theoretically even web) we write a runtime that converts the metadata into runtime UIs. So it ends up being custom logic for interaction on each platform, but the design/assets can be shared cross-platform.
