The reason SwiftUI in a static framework can't show previews is due to the architecture of Xcode Previews. This year, Xcode Previews has introduced a new dynamic linking architecture that uses the same build artifacts for both previews and when you build and run your project. This avoids the need to rebuild your project when switching between the two, making the workflow smoother and more productive. However, static frameworks do not support this dynamic linking architecture, which is why previews are not available in that context.

For more details, you can refer to the Platforms State of the Union (37:45) session.
