swift-simplifier

Reports behavior-preserving Swift simplifications — guard/optional cleanups, if/switch expressions, collection idioms, redundant boilerplate, and dead availability guards — each tagged by how safe it is to apply. Point it at a file, a subsystem, or the whole project.

What It Does

• Detects local, behavior-preserving Swift-language simplifications (control flow, optionals, collections, closures, boilerplate, error handling)
• Tags every finding SAFE / PRECONDITION / ADVISORY so you know what to verify before applying
• Flags always-true if #available guards against your deployment floor (Axiom-specific)
• Reports only — it does not edit; you apply findings (main loop, a simplify pass, or by hand)

Note: This is clarity-only and behavior-preserving. For old→new API migration use modernization-helper; for speed use swift-performance-analyzer; for SwiftUI structural moves (extract/decompose) use swiftui-architecture-auditor.

How to Use

Natural language:

• "Simplify this Swift file"
• "Make MyService.swift more idiomatic"
• "Point swift-simplifier at the Networking subsystem"

Explicit command:

/axiom:audit swift-simplify

Related

• axiom-swift skill — modern-idiom source this auditor draws from; use it to apply a finding
• modernization-helper agent — old→new API migration (complementary; owns .filter{}.count as a modernization)
• swift-performance-analyzer agent — speed rewrites (defer to it when clarity and perf conflict)
• swiftui-architecture-auditor agent — SwiftUI structural moves (this agent does local cleanups only)
