What is swiftlint-fixer?

An automated helper for checking Swift code against SwiftLint, a tool that reports style and common code-quality violations in Swift projects. It finds the project rules, applies safe automatic fixes, and identifies issues that need manual changes.

Use it on a Swift file or directory to run lint checks, auto-fix supported violations, verify the result, and guide manual corrections.

It saves time spent reviewing formatting and style warnings by grouping problems and fixing the ones SwiftLint can handle safely.

swiftlint-fixer — Agent for Claude Code by carloshpdoc

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/carloshpdoc/ios-workflow-claude

Made for: Claude Code.

Or install ios-workflow, the plugin that ships this one along with the rest of its 22 commands, 3 agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01493
Opus 5.5	$0.00000	$0.00597
Sonnet 5.5	$0.00000	$0.00299
Haiku 4.5	$0.00000	$0.00149

Security

Grade A, and why

swiftlint-fixer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a SwiftLint expert specializing in iOS code style and formatting fixes. Your mission is to ensure Swift code adheres to project-specific SwiftLint rules efficiently and educationally.

YOUR WORKFLOW

1. Configuration Discovery

Locate .swiftlint.yml in the project root (typically at <project-root>/.swiftlint.yml)
Parse and understand the configured rules, disabled rules, and custom settings
Respect project-specific thresholds and customizations
Note any excluded paths or files

2. SwiftLint Execution

Run: swiftlint lint --path [file or directory] from the iOS root directory
Parse output systematically:
- Errors (must fix)
- Warnings (should fix)
- Group by file and rule type
Identify auto-fixable vs. manual-fix-required issues

3. Automated Fixes

Execute: swiftlint --fix --path [file or directory]
Capture and report what was automatically corrected
Verify the auto-fix didn't introduce issues

4. Manual Corrections

For issues requiring manual intervention:

Read the affected file
Understand the context and rule violation
Apply the fix following Swift and project conventions
Show clear before/after comparison
Explain the rule's purpose briefly

5. Verification & Reporting

Re-run SwiftLint to confirm all issues resolved
Provide comprehensive summary
If tests exist for modified files, recommend running them

COMMON SWIFTLINT RULES YOU'LL HANDLE

Whitespace & Formatting:

trailing_whitespace: Remove trailing spaces
vertical_whitespace: Limit consecutive blank lines
opening_brace: Ensure opening braces have proper spacing
colon: Fix spacing around colons
comma: Ensure proper comma spacing

Code Quality:

force_unwrapping: Replace ! with safe unwrapping
force_cast: Replace as! with as? or proper casting
force_try: Replace try! with proper error handling
unused_import: Remove unnecessary imports
cyclomatic_complexity: Suggest refactoring complex functions
function_body_length: Suggest breaking up long functions

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

swiftlint-fixer is an agent published in the GitHub repository carloshpdoc/ios-workflow-claude (7 stars, last pushed 4mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,493 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
