Battle-tested Claude Code skills for modern xOS (iOS, iPadOS, watchOS, tvOS) development

What it solves

Axiom provides AI coding assistants with specialized, deep expertise in Apple OS development. It prevents common high-impact errors such as data loss from bad migrations, memory leaks, and concurrency violations, while reducing the time spent debugging build failures and system processes.

How it works

Axiom integrates as a plugin or via the Model Context Protocol (MCP) into AI coding harnesses like Claude Code, Cursor, VS Code, and Xcode. It provides a library of hundreds of "skills" and autonomous agents that can be triggered automatically by user questions or via direct commands. It includes built-in tools for console capture (xclog), crash symbolication (xcsym), UI validation (xcui), and performance trace analysis (xcprof).

Who it’s for

Apple OS developers using AI-powered IDEs or coding agents who want to automate diagnostics, audits, and the implementation of modern Swift and SwiftUI patterns.

Highlights

  • Extensive Knowledge Base: Includes 273 skills and 42 autonomous agents covering UI, data, concurrency, and performance.
  • Diagnostic Tooling: Built-in capabilities to capture simulator logs, symbolicate crash reports, and analyze CPU traces without needing Instruments.
  • UI Validation: Tools to drive the simulator UI and check accessibility, VoiceOver, and Dynamic Type.
  • Detailed Audits: Dedicated commands to scan for memory leaks, data races, and build failures.
  • tDD-Tested: Every discipline skill is tested against real-world developer pressure scenarios.
