Raven 0.11.1

Raven 0.11.1

Patch release that fixes a couple of rough edges in anchor preferences introduced in 0.11.0.

Fixed

• anchorPreference now tags nested fragment descendants for anchor groups (fixes anchors resolving to .zero for fragment-of-fragments output, e.g. ForEach/tuple builders).
• Anchor geometry resolution now converges after DOM mutations commit by scheduling a follow-up render when resolved anchor rects change (reduces stale overlay positions after layout-affecting updates).

Raven 0.11.0

Raven 0.11.0

This release adds a SwiftUI-like preferences system (including anchor preferences) so child views can propagate values and geometry up the tree and ancestors can read/observe them.

Added

• PreferenceKey + PreferenceValues
• Preference modifiers:
  • preference(key:value:)
  • transformPreference(_:_:)
  • onPreferenceChange(_:perform:) (runs post-render)
  • overlayPreferenceValue(_:alignment:_:)
  • backgroundPreferenceValue(_:alignment:_:)
• Anchor preferences (initial support):
  • Anchor<CGRect>
  • anchorPreference(key:value:transform:)
  • GeometryProxy anchor resolution (geo[anchor]) on WASM via DOM measurement

Behavior Notes

• Preference reduction is applied in flattened view-tree order (SwiftUI-like).
• onPreferenceChange is deferred to after the render pass to avoid re-entrant renders.

Demo

The TodoApp example includes a new Prefs tab demonstrating both preference aggregation and Anchor<CGRect> resolution.

Raven 0.10.3: SwiftUI module alias support

Highlights

• Apps can write import SwiftUI (no direct import Raven) when building for WASI, by using SwiftPM moduleAliases.
• New umbrella module: RavenSwiftUI (re-exports Raven + RavenRuntime).

What’s New

• Root package now ships RavenSwiftUI as a product/target.
• Examples/TodoApp uses:
  • .product(name: "RavenSwiftUI", package: "Raven", moduleAliases: ["SwiftUI": "RavenSwiftUI"], condition: .when(platforms: [.wasi]))
• Tests updated so TodoApp is allowed to import SwiftUI while other examples still enforce import Raven.

Demo

swiftly run swift run raven dev --input Examples/TodoApp

Raven 0.10.2: Asset Catalogs (.xcassets) + Custom Symbols (.symbolset)

Highlights

• First-class Xcode Asset Catalog (.xcassets) support in Raven’s CLI + runtime.
• Loads assets by name at runtime:
  • Image("Name") (imagesets with srcset)
  • Color("Name") (colorsets via injected CSS variables, including light/dark)
  • Asset.url("Name") / Asset.fetchData("Name") (datasets)
• Supports custom symbol assets from Xcode Symbol Image Sets (.symbolset), rendered tintably (inherits currentColor).

What’s New

Asset Catalog Compilation (CLI)

• Discovers and compiles *.xcassets from:
  • The app package under Sources/**
  • SwiftPM dependency checkouts (via .build/workspace-state.json and .build/checkouts/**/Sources/**)
• Emits a manifest and injects it into served/generated HTML so assets resolve before main() runs.
• Deterministic asset IDs shared between CLI and runtime (RavenAssetSupport).

Dev + Build Integration

• raven dev watches .xcassets changes (including dependency catalogs) and rebuilds.
• raven build produces a self-contained dist/ with compiled assets under /assets/ and the manifest injected into index.html.

Runtime APIs

• Image("...") resolves via the injected manifest when available; falls back to /assets/<name> for compatibility.
• Color("...") resolves through injected CSS variables.
• New Asset helper for datasets.

Demo

Examples/TodoApp includes a ready-to-run asset catalog demo:

• RavenMark.imageset (README raven mark)
• BrandPrimary.colorset (light/dark)
• SampleText.dataset
• RavenCustom.symbolset and git.*.symbolset

Run it:

Raven % swiftly run swift run raven dev --input Examples/TodoApp

Notes

• Image assets are copied as-is (no transcoding/optimization in this release).
• Package swift settings were cleaned up to avoid flags that break Xcode builds.

Thanks to everyone improving Raven’s reliability and developer experience in this cycle.

v0.10.0

Highlights

Massive release: 55 commits, 445 files changed, +89K/-36K lines. Raven now has a native Swift CLI, fiber-based incremental reconciliation, fully reactive ObservableObject support, and a working WASM runtime with hot reload.

Raven CLI

New native Swift CLI replacing the Python tooling:

• raven build - Production WASM builds with optimization, stripping, and Brotli compression
• raven dev - Hot reload dev server with SSE-based live reload on file changes (localhost:3000)
• raven create - Project scaffolding
• Automatic SwiftWasm toolchain detection (Swift SDK, carton, or SwiftWasm)
• Bundle size analysis with detailed breakdown
• Enhanced compiler error reporting

Fiber Reconciliation

React Fiber-inspired incremental rendering engine:

• O(dirty) reconciliation - only re-renders changed subtrees, skips clean branches
• State batching via requestAnimationFrame - multiple state changes coalesce into one render
• PlatformRenderer abstraction decouples reconciliation from DOM operations
• Stable path-based node IDs survive re-renders for handler persistence
• Dual-tree architecture (current + work-in-progress)

Mirror-Free Rendering

Eliminated all Mirror reflection from the rendering pipeline (Mirror crashes in Swift WASM):

• New _CoordinatorRenderable protocol - views render themselves using a _RenderContext
• _ModifierRenderable convenience protocol for modifier views
• All container views (VStack, HStack, ZStack, List, ScrollView) and interactive views (Button, TextField, Toggle, Slider, Picker) converted

ObservableObject Reactivity Fix

Fixed @StateObject and @ObservedObject not triggering re-renders:

• objectWillChange subscriptions now call _RenderScheduler.current?.scheduleRender() directly
• Bypasses the defunct Mirror-based setupStateCallbacks mechanism
• @Published property changes properly propagate through the entire render pipeline

SwiftUI App Protocol

Full @main support with App/Scene protocol hierarchy:

• Scene lifecycle tracking (active/inactive/background) via browser visibility/focus events
• Automatic framework CSS injection on launch
• JavaScriptEventLoop.installGlobalExecutor() wired automatically

WASM Runtime

• WASI reactor ABI support (-mexec-model=reactor, --export-if-defined=main)
• HTML bootstrap calls main() / __main_argc_argv(0,0) after _initialize()
• Counter-based UUID generation (WASI random_get polyfill is broken)
• Fixed event handler registration, lifecycle, and stale handler cleanup
• Input focus preservation during re-renders

Dark Mode

• 17 semantic CSS custom properties (--system-primary, --system-background, --system-accent, etc.)
• @media (prefers-color-scheme: dark) overrides
• Runtime matchMedia listener triggers re-render on OS theme change

New Components

• AsyncImage - Async loading with placeholder/error states
• Menu - Context menus with nested actions
• DisclosureGroup - Expandable content with CSS animations
• Grid - Flexible 2D grid layout
• GroupBox - Labeled content container
• ControlGroup - Grouped control styling
• ScrollView - Horizontal/vertical/bidirectional scrolling
• LazyVStack - Lazy loading with pinned headers/footers
• Canvas - Immediate-mode drawing with GraphicsContext
• 85 built-in symbols organized by category (shapes, arrows, media, status, navigation)

TodoApp Component Showcase

Full interactive demo app with 6 tabs: Todos, Controls, Display, Layout, Forms, Effects. Demonstrates CRUD operations, state binding, all major controls, and layout primitives running in the browser.

Swift 6 Strict Concurrency

• Full compliance across all 279 source files and 89 test files
• @MainActor isolation on all UI types
• @Sendable closures for all event handlers
• Builds clean on macOS, Linux (Ubuntu 22.04), and WASM

Cleanup

• Removed 37K+ lines of orphaned phase docs, Python CLI, and loose example files
• Removed dead Differ/CommitPhase code
• Cleaned tracked .wasm binaries

Testing

878 passing tests across 89 test files covering fiber reconciliation, state reactivity, gestures, forms, accessibility, presentation, virtual scrolling, and list features.

Raven v0.6.0 - Phase 12: Animation Foundation

This massive release brings Raven's SwiftUI API coverage from ~80% to ~85% with a complete animation system including implicit/explicit animations, transitions, and keyframe animations.

🌟 Highlights

• Complete Animation System - Timing curves, spring physics, custom Bézier
• Implicit & Explicit Animations - .animation() modifier and withAnimation()
• 8 Transition Types - View appearance/disappearance animations
• Keyframe Animations - Multi-step animations with interpolation
• 218+ Tests - Comprehensive coverage
• Complete Documentation - 1,550+ line animation guide

---

✨ New Features

Animation Foundation

Animation Types:

// Standard curves
.animation(.default)      // Ease-in-out
.animation(.linear)       // Constant speed
.animation(.easeIn)       // Slow start
.animation(.easeOut)      // Slow end

// Spring physics
.animation(.spring())
.animation(.spring(response: 0.3, dampingFraction: 0.6))

// Custom curves
.animation(.timingCurve(0.4, 0.0, 0.2, 1.0, duration: 0.3))

Animation Modifiers:

.animation(.spring()
    .delay(0.1)
    .speed(1.5)
    .repeatCount(3, autoreverses: true))

---

Implicit Animations (.animation() Modifier)

Automatically animate property changes:

@State private var isExpanded = false

Circle()
    .scaleEffect(isExpanded ? 1.5 : 1.0)
    .animation(.spring())  // Animates when isExpanded changes

Button("Toggle") {
    isExpanded.toggle()  // Triggers animation
}

Value-Based Animation (More Efficient):

Text("Count: \(count)")
    .animation(.easeInOut, value: count)  // Only animates when count changes

Two Variants:

• .animation(_:) - Animate all changes
• .animation(_:value:) - Animate only when value changes

---

Explicit Animations (withAnimation() Function)

Animate state changes explicitly:

Button("Animate") {
    withAnimation(.spring()) {
        isExpanded.toggle()
        opacity = 0.5
        scale = 1.2
    }  // All changes animated with spring
}

With Completion:

withAnimation(.easeOut, {
    showDetails = true
}, completion: {
    print("Animation finished!")
})

Features:

• Nested animation support
• Completion callbacks
• Error propagation
• Thread-safe with @mainactor

---

Transition System

8 Transition Types for view appearance/disappearance:

// Fade in/out
if showView {
    DetailView()
        .transition(.opacity)
}

// Scale from center
if showCard {
    CardView()
        .transition(.scale)
}

// Slide from edge
if showMenu {
    MenuView()
        .transition(.move(edge: .leading))
}

// Custom translation
if showBanner {
    BannerView()
        .transition(.offset(y: -100))
}

// Navigation-style push
if showDetail {
    DetailPage()
        .transition(.push(from: .trailing))
}

Available Transitions:

1. .identity - No animation
2. .opacity - Fade in/out
3. .scale(scale:anchor:) - Scale with anchor point
4. .slide - Slide from bottom
5. .move(edge:) - Slide from specific edge
6. .offset(x:y:) - Custom translation
7. .push(from:) - Navigation-style (maintains opacity)
8. .modifier(active:identity:) - Custom via ViewModifiers

Composition:

// Combine multiple transitions
CardView()
    .transition(.scale.combined(with: .opacity))

// Different insert/remove
CardView()
    .transition(
        .asymmetric(
            insertion: .scale,
            removal: .opacity
        )
    )

---

Keyframe Animations (iOS 17+)

Multi-step animations with different interpolation per step:

Circle()
    .keyframeAnimator(
        initialValue: AnimationValues(scale: 1.0, opacity: 1.0),
        repeating: true
    ) { content, value in
        content
            .scaleEffect(value.scale)
            .opacity(value.opacity)
    } keyframes: { track in
        // Linear interpolation
        track.linear(.init(scale: 1.2, opacity: 0.8), duration: 0.3)
        
        // Spring physics
        track.spring(.init(scale: 1.0, opacity: 1.0), duration: 0.4, bounce: 0.2)
        
        // Instant change
        track.move(.init(scale: 1.5, opacity: 0.5))
        
        // Cubic ease
        track.cubic(.init(scale: 1.0, opacity: 1.0), duration: 0.3)
    }

Keyframe Types:

• LinearKeyframe - Constant speed
• SpringKeyframe - Physics-based (bounce: 0.0 - 1.0)
• CubicKeyframe - Smooth ease-in-out
• MoveKeyframe - Instant jump

Interpolatable Types:

• Double, Float, CGFloat
• CGPoint, CGSize, CGRect
• Extensible for custom types

🎓 Common Patterns

Button Bounce:

Button("Press Me") { }
    .scaleEffect(isPressed ? 0.9 : 1.0)
    .animation(.spring(response: 0.3, dampingFraction: 0.6))

List Insert/Remove:

ForEach(items) { item in
    ItemRow(item)
        .transition(.move(edge: .trailing).combined(with: .opacity))
}

Loading Spinner:

Circle()
    .trim(from: 0, to: 0.7)
    .stroke(lineWidth: 3)
    .keyframeAnimator(initialValue: 0.0, repeating: true) { content, angle in
        content.rotationEffect(Angle(degrees: angle))
    } keyframes: { track in
        track.linear(360, duration: 1.0)
    }

Page Transition:

if showDetail {
    DetailView()
        .transition(.push(from: .trailing))
}
withAnimation(.easeOut) {
    showDetail = true
}

---

🚀 Migration Guide

From Static to Animated

Before:

@State private var scale: CGFloat = 1.0

Circle()
    .scaleEffect(scale)

Button("Grow") {
    scale = 1.5  // Instant change
}

After:

@State private var scale: CGFloat = 1.0

Circle()
    .scaleEffect(scale)
    .animation(.spring(), value: scale)  // Smooth animation

Button("Grow") {
    scale = 1.5  // Animated change
}

Choosing Animation Style

Use .animation() when:

• Property changes should always animate
• Simple property-based animations
• Visual feedback on state changes

Use withAnimation() when:

• Multiple related state changes
• Conditional animation
• Need completion callbacks
• Complex animation choreography

✨ New Features

Modern Layout APIs

1. containerRelativeFrame() (iOS 17+)

A modern alternative to GeometryReader for responsive layouts:

// Closure-based sizing
Image("hero")
    .containerRelativeFrame(.horizontal) { width, _ in
        width * 0.8
    }

// Grid-based sizing
Rectangle()
    .containerRelativeFrame(.horizontal, count: 3, span: 2, spacing: 10)

Features:

• Closure-based sizing calculations
• Grid-based responsive layouts
• Axis control: .horizontal, .vertical, .all
• CSS container queries implementation
• Better performance than GeometryReader

2. ViewThatFits (iOS 16+)

Automatically selects the first layout variant that fits:

ViewThatFits(in: .horizontal) {
    // Desktop: Full navigation
    HStack {
        Image("logo")
        Text("My App Name")
        Spacer()
        Button("Sign In") { }
        Button("Sign Up") { }
    }

Scroll Enhancements

1. scrollBounceBehavior() (iOS 17+)

Control scroll bounce/overscroll behavior:

ScrollView {
    // content
}
.scrollBounceBehavior(.basedOnSize)  // No bounce when content fits
.scrollBounceBehavior(.always, axes: .horizontal)  // Always bounce horizontally

BounceBehavior Options:

• .automatic - Default browser behavior
• .always - Always allow bounce
• .basedOnSize - Bounce only when content exceeds container

2. scrollClipDisabled() (iOS 17+)

Allow content to extend beyond scroll bounds:

ScrollView {
    // Cards with shadows
    ForEach(items) { item in
        CardView(item)
            .shadow(radius: 10)  // Shadow visible outside scroll
    }
}
.scrollClipDisabled()

3. scrollTransition() (iOS 17+)

Scroll-driven animations with phases:

ScrollView {
    ForEach(items) { item in
        ItemCard(item)
            .scrollTransition { content, phase in
                content
                    .opacity(phase.isIdentity ? 1 : 0)
                    .scaleEffect(phase.isIdentity ? 1 : 0.8)
            }
    }
}

ScrollTransitionPhase:

• .topLeading - Element entering from top
• .identity - Element fully visible
• .bottomTrailing - Element leaving at bottom

Common Patterns:

• Fade in/out
• Scale effects
• Blur transitions
• Slide animations

• IntersectionObserver API - Scroll position tracking
• CSS overscroll-behavior - Bounce control
• HTML Search Input - Native search with suggestions
• CSS Transitions - GPU-accelerated animations

Browser Compatibility:

Feature	Chrome	Safari	Firefox	Edge
Container Queries	105+	16+	110+	105+
IntersectionObserver	51+	12.1+	55+	15+
Overscroll Behavior	63+	16+	59+	18+
Search Input	All	All	All	All

Graceful Degradation:

• Fallback to last variant for ViewThatFits
• Default scroll behavior for older browsers
• Progressive enhancement throughout

🚀 Migration Guide

From GeometryReader to containerRelativeFrame()

Before:

GeometryReader { geometry in
    Image("hero")
        .frame(width: geometry.size.width * 0.8)
}

After:

Image("hero")
    .containerRelativeFrame(.horizontal) { width, _ in
        width * 0.8
    }

Benefits:

• Simpler code
• Better performance
• Native CSS implementation
• No layout coordination needed

---

🎓 Use Cases
