Add iOS 18 Zoom Navigation Transitions To A SwiftUI Grid

This article explains how to implement iOS 18's zoom navigation transitions in a SwiftUI grid. It covers setting up a stable model with UUID identifiers, creating a namespace for the transition, and using the zoomTransitionSource modifier to connect a grid tile to its detail view. The transition provides a smooth, zooming animation between thumbnail and full view, enhancing user experience. The article includes sample code for a GalleryItem model and a GalleryGridView, and notes that the API is available on iOS 18, iPadOS 18, tvOS 18, watchOS 11, and visionOS 2, with a fallback for iOS 17.
