reorderable() and reorderContainer(for:): Native Drag-to-Reorder for Any SwiftUI Layout

Reordering in SwiftUI has only ever really meant one thing: put your data in a List, attach .onMove(perform:), and accept the drag handle, the edit-mode chrome, and the row layout that comes with it. The moment your design called for a grid, a Kanban board, or anything built

dropConfiguration in SwiftUI: Live Drag-and-Drop Targeting Without the Coordinate-Space Guesswork

Ever build a Trello-style board and hit the wall where dropDestination can only tell you "something got dropped here" — not which column the user's finger is hovering over right now? Live column targeting, the kind where a card visibly snaps to the column you'

EmptyModifier in SwiftUI: Debug-Only View Modifiers That Vanish From Release Builds

Every SwiftUI codebase collects a few view modifiers that should only exist during development: a red border around a view that's fighting the layout system, a caption showing a view's live frame size, an overlay flagging which cell came from a mock network response. The obvious

SwiftUI's TextEditor Finally Speaks AttributedString: A Practical Guide to iOS 26 Rich Text

TextEditor has only ever accepted a plain String binding. The moment an app needed anything richer than that — a bold heading, a colored word, an inline link — the SwiftUI-only toolkit ran out, and the fallback was always the same: wrap UITextView in a UIViewRepresentable, write an NSObject-based Coordinator

visualEffect in SwiftUI: Scroll-Driven Effects Without GeometryReader Breaking Your Layout

You want a photo to fade and shrink as it scrolls off the top of the screen. The instinct, drilled in by years of SwiftUI tutorials, is to wrap it in a GeometryReader, read the frame, and drive the effect from there. Then your layout falls apart: the cards collapse

geometryGroup() in SwiftUI: Why Your Custom Animation Curve Gets Ignored

You wired up a phaseAnimator to shake a button when a form fails validation, and you wrote a short, sharp .linear curve in the animation: closure so the shake feels mechanical. You run it — and the button springs instead. Soft, bouncy, completely wrong. The curve you asked for is being

Why Your @Observable View Isn't Updating: SwiftUI Tracks Reads, Not Writes

A property changes and the view doesn't move. You can log the new value, you can watch it tick over in the debugger, but the UI keeps showing the old one. There's no crash, no console warning, no purple runtime issue — and the line that should

SwiftUI View Identity: Why an If Statement Breaks Your Animations

You add a conditional to a view — highlight a selected cell, dim an archived row — and reach for the tool every Swift developer knows: an if statement. The code compiles, the logic is correct, and yet the result is subtly wrong. The animation snaps instead of glides, or a text

onScrollGeometryChange: Track Scroll Position in SwiftUI Without Tanking Performance

For years, reading a scroll view's offset in SwiftUI meant the same awkward dance: drop a GeometryReader into the content, publish the frame through a PreferenceKey, define a custom coordinate space, and read it all back out somewhere up the tree. It worked, but it added phantom views

Branching Haptics in SwiftUI: Getting More Out of sensoryFeedback

Most apps reach for sensoryFeedback exactly once and wire it to a single outcome: a button tap plays .impact, a save plays .success. That works, but it leaves most of the API on the table. The modifier was built to branch — one declaration can pick a different haptic for success,
