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.
