A short guide on integrating QuickLook into SwiftUI apps to preview URL-based content such as PDFs and images. By importing the QuickLook framework and applying the `.quickLookPreview` view modifier bound to a URL state variable, developers can trigger platform-appropriate previews on both iOS (full screen cover) and macOS (modal). The feature is not available on tvOS or watchOS, but conditional compilation directives can handle multi-platform scenarios.
