Swift Adwaita 1.1.0 has been released. I’ve been working on a first app built with this library, so I’ve extended it and fixed some bugs.

Highlights

• Added GtkSourceView integration with typed Swift wrappers for source editing, syntax highlighting, languages, and style schemes.
• Expanded widget APIs around popovers, windows, calendar compatibility, and runtime lifecycle handling.
• Improved release stability with better GLib main-loop integration, broader CI coverage, and additional regression tests.

Added

• SourceView, SourceBuffer, SourceLanguage, SourceLanguageManager, SourceStyleScheme, and SourceStyleSchemeManager.
• Typed identifiers for GtkSource languages and style schemes.
• A new source editor demo example.
• MainContext.task { ... }, task(after:), and task(every:) as cancellable GLib main-loop work handles.
• Async MainContext.run, yield, and sleep(for:) helpers for bridging Swift concurrency onto the GLib loop safely.
• Widget.unparent() and PopoverMenu.unparent().
• Convenience presentation helpers for Popover and PopoverMenu.
• Additional regression tests for widget/window parent-chain lookup and expanded coverage for source editing and media behavior.

Changed

• GtkWindow.present() now retains windows until close, making transient or locally scoped windows safer to use.
• Widget.window now resolves the containing window through the widget parent chain instead of assuming the GTK root is always a window.
• Calendar date handling now uses a GTK compatibility shim so the package builds cleanly across older and newer GTK versions.
• Documentation generation and hosted docs configuration were updated.
• CI now installs and tests with GtkSourceView 5 system dependencies.

Fixed

• Fixed deferred signal/user-data cleanup to release captured closures through the GLib main loop instead of Swift main-queue tasks, avoiding lifecycle issues in GTK applications.
• Fixed a common GTK scheduling pitfall by offering a Task-like API that stays on the GLib main loop instead of DispatchQueue.main.
• Fixed Swift 6.1 serialized suite visibility issues in the test suite.
• Fixed the popover/window regression tests to avoid GTK crash paths in CI while still validating the intended behavior.
• Fixed release documentation and installation instructions to include GtkSourceView 5 development packages.

Documentation and CI

• Added an API documentation link to the README.
• Updated installation instructions for Ubuntu/Debian and Fedora.
• Improved inline documentation consistency across the wrapper API.
• Extended CI coverage for documentation, formatting, and Swift 6.1 / 6.2 / 6.3 test runs.

This release focuses on Swift 6.3 compatibility, a substantial rewrite of the editor's highlighting pipeline, and much better responsiveness when editing very large HTML documents.

Added

• Added the HTMLEditorBenchmarks executable target for repeatable performance measurements.
• Added benchmark support for full-plan highlighting, overlap reuse, edit invalidation, visible-highlight remapping, and large-document local repaint paths.
• Added focused regression tests for:
  • planner cache reuse and document-scoped invalidation
  • invalid NSRange and UTF-16 edge cases
  • quoted and unquoted attribute value highlighting
  • visible highlight state remapping
  • block-based highlight coverage
  • large-document editing and scrolling policies

Changed

• Refactored the editor runtime into smaller focused components, including separate coordinator lifecycle, viewport, editing, policy, coverage, structural-range, and visible-highlight-state files.
• Refactored the syntax highlighter into planner- and builder-based components for clearer separation of scanning, planning, and application.
• Moved the editor to an adaptive runtime model that changes behavior based on document size instead of treating all HTML documents the same way.

Improved

• Greatly improved large-document editing performance with:
  • viewport-first highlighting
  • document-scoped planner caches and targeted invalidation
  • cached visible-range plans
  • block-based highlight coverage tracking
  • structural dirty-range alignment around edits
  • two-phase large-file editing with immediate micro-pass and deferred wider repaint
  • burst-coalesced edit repainting
  • scroll-idle semantic highlighting
  • deferred binding synchronization for large documents
  • allowsNonContiguousLayout enabled automatically in large-file mode
• Improved highlight stability while typing in the middle of very large HTML by preserving visible overlay state and reducing repaint churn around the caret.
• Improved performance tuning and observability for large files with dedicated benchmark coverage and runtime probes.

Fixed

• Fixed compilation and concurrency issues needed for Swift 6.3 compatibility.
• Fixed several editor update-path issues related to coordinator state, highlighting tasks, and main-actor behavior.
• Fixed highlight regressions and edge cases involving:
  • partial tags
  • empty input
  • large payloads
  • attribute-value coloring
  • visible highlight loss during large-file editing
  • invalid or clipped visible ranges

Notes

• Full-document semantic highlighting is still used for smaller HTML inputs.
• Very large HTML inputs now automatically switch to a more conservative, performance-oriented editing mode to keep scrolling and typing responsive.

A project that I’ve always wanted to create: a library that enables the development of GNOME applications using Swift. While there are some similar libraries available, they appear to be incomplete or not actively maintained. Thanks to Vibe Coding, I managed to complete the project in approximately a week.

swift-adwaita is an imperative Swift 6 wrapper for GTK4 and libadwaita, built for creating native GNOME desktop applications on Linux.

It provides a modern Swift API over GTK and Adwaita with type-safe widgets, signals, property bindings, async operations, and ergonomic convenience helpers, while preserving the native behavior, styling, and feel of the GNOME platform.

• Native GTK4 and libadwaita application development in Swift
• Imperative API without a custom DSL
• Type-safe enums, signals, and property APIs
• Async/await support for common platform integrations
• Extensive widget coverage with a real demo application

Here’s a demo app built using swift-adwaita:

Actioneer 1.0.8 focuses on making live GitHub Actions monitoring more reliable while using the GitHub API more efficiently.

Highlights

• In-progress workflow runs now keep refreshing while they are still active, so expanded jobs and steps stay current before the run finishes.
• Expanded run details are more stable and easier to read, with clearer badges, preserved job context, and contiguous step numbering.
• Workflow status badges are now translated more consistently across the app's supported languages.
• Background refresh is lighter on the GitHub API, reducing duplicate requests and helping preserve rate-limit headroom.

Technical improvements

• Fixed several live-refresh lifecycle issues in the detail pane so switching repositories or rebuilding rows no longer disables the active refresh loop.
• Removed duplicate initial jobs fetches caused by rerender races around freshly expanded runs.
• Reduced unnecessary polling pressure by tightening selected-repo refresh ownership and job-refresh reuse.

Actioneer for Linux has translations available in numerous languages, including Russian, Spanish, French, Portuguese (Brazil), Hindi, Simplified Chinese, Arabic, Bengali, Urdu, German, and Dutch.

It also includes a built-in crash reporter, which you can copy and paste the report or open an issue on GitHub. Additionally, there are some tweaks and improvements made under the hood.

There were a bunch of updates of Actioneer for Linux recently, which I forgot to post here. Here's what's new in these updates:

1.02

• Faster and smoother UI with refreshed repo/workflow lists and improved scrolling behavior.
• New run filtering controls with better caching, so switching filters is instant and doesn’t reload data.
• Better workflow auto-refresh and run status updates, including fewer duplicate fetches.
• Notifications are more reliable across Snap/Flatpak, with improved icon handling and fallbacks.
• Improved sandboxed credential storage using the secret portal for Snap/Flatpak.
• Offline-friendly cache persistence for workflows, runs, and jobs.
• Packaging and CI updates across Snap, Flatpak, and AppImage for better compatibility.
• Dependency updates and stability fixes.

1.03

• Job logs now render ANSI colors, grouped workflow sections, and clearer command/output formatting.
• Aligned timestamps and command prefixes improve scanability, with stronger error highlighting.
• Packaging CI refreshed with multi-arch updates for AppImage/Snap/Flatpak builds.
• Dependency updates and demo log refreshes for improved accuracy.

1.04

• Handle expired job logs (HTTP 410) with clearer messaging instead of a broken view.
• Strip BOM markers in job logs so first-line timestamps render correctly.

1.05

• Manual workflow triggers now support workflow_dispatch inputs with dynamic parameter fields.
• Dependency updates for ryu, unicode-ident, and zmij.
