Build Custom Transitions in SwiftUI (Zoom, Modals, Flip Cards & More)

#ios #swift #mobile #programming

Let’s be honest:

You add one SwiftUI transition and suddenly…

The back gesture breaks
Matched geometry glitches
The animation works… but only on Tuesdays 🤷‍♂️

I ran into all of this — so I built custom transitions that actually work in real apps:

🎯 What we’ll build:

📸 A Zoom-style photo transition using .navigationTransition(.zoom)
📱 A card-to-detail expansion like the App Store
🎭 A modal sheet with .presentationDetents() and drag indicator
🔄 A flip card with 3D perspective using AnyTransition.modifier

Here's a sneak peek: Zoom transition with real navigation stack support

NavigationLink(value: photo) {
    PhotoThumbnail(photo)
}
.matchedTransitionSource(id: photo.id, in: namespace)

.navigationDestination(for: Photo.self) { photo in
    PhotoDetailView(photo: photo)
        .navigationTransition(.zoom(sourceID: photo.id, in: namespace))
}
