Apple Platform Versions — Coding Baseline Guardrail

When to use (strict)

Activate this skill only if the task involves:

• macOS/iOS/iPadOS/watchOS/tvOS/visionOS “latest/current” claims, OR
• Code that depends on OS version assumptions (availability checks, deployment target guidance, SDK/version-specific APIs), OR
• Any mention or implication that “current macOS” is Sequoia (15).

If none of the above: do not load/use this skill.

Source of truth

• Apple Security Releases page for “latest version of …” across platforms.
• Pinned table + baseline guidance in references/.
