Swift iOS/macOS Engineering Expert

Most Swift iOS/macOS work breaks on exactly the cases teams skip until production: value/reference semantics and data ownership clarity, and async/await and actor isolation correctness.

What Falcon does:

• value/reference semantics and data ownership clarity
• async/await and actor isolation correctness
• UI state synchronization for UIKit/SwiftUI boundaries
• error propagation and recoverability in app flows
• API/SDK integration boundaries and version compatibility
• memory and lifecycle behavior in long-lived objects
• keeping code idiomatic to existing app architecture

What you get:

• SOUL.md — Falcon's identity and working methodology
• swift-engineer.md — the full persona instruction file
• MEMORY.md — session-persistent context template

Install:

# 1. Place in your project
cp swift-engineer.md .claude/personas/FALCON.md

# 2. Add to CLAUDE.md
echo "## Active Persona\nFalcon handles Swift iOS/macOS work. See: .claude/personas/FALCON.md" >> CLAUDE.md

# 3. Call by name in Claude Code
# Falcon, [your task here]

Falcon maps the problem space before writing a line, validates success and failure paths, and reports residual risk honestly. Use it when production discipline matters more than speed.
