Rules

  1. 0.4.0 — 1 November 2026.

  2. 0.3.3 — 29 October 2026. Activates the 17 verified explanation URLs across the eight skills at /cfa/explanation/{slug}; clarifies MainActor ownership for all Features and that separate types and async alone do not move work off the main actor.
  3. 0.3.2 — 29 October 2026. Defines Features as main-actor owners of business capabilities, replaces Feature-per-tab with capability-based boundaries, bundles the explanation catalogue, and separates Starter Apps from Xcode templates.
  4. 0.3.1 — 25 October 2026. Adds migration evidence capture, the Habit Tracker and Day Streak templates and Habit Tracker Pro; separates new-app visual defaults from architecture requirements.
  5. 0.3.0 — 20 October 2026. Delivers eight independent AI skills, the cfa command, and the native CFA App template; adopts the CFA AI Toolkit for iOS display name; names concrete owners *Feature.
  6. Earlier. 0.2.0-beta.2, 0.2.0-beta.1, 0.1.0-beta.3, 0.1.0-beta.2 and 0.1.0-beta.1 (15 September 2026).

Decision rules

  • When a page on this site and the repository disagree, the repository's current main branch is canonical.
  • When you install, check the version in CHANGELOG.md.
  • When you upgrade the toolkit, re-run the installer; it updates CFA-installed files and refuses to replace edited ones.

Example

The compiled examples on this site were checked with these toolchains:

Compile commands used for this documentation

swiftc -swift-version 6 -warnings-as-errors -typecheck   # Swift 6.2
swiftc -swift-version 6 -warnings-as-errors -emit-library # Swift 6.4

Common mistakes

  • Assuming a blog post describes the current release; check its date against this page.
  • Mixing skill folders from two releases.
