Why Guidelint?

You've spent weeks building your app. You submit it. Then you wait. Days later — rejected.

Missing PrivacyInfo.xcprivacy. A NSCameraUsageDescription that says "We need camera access." An http:// URL hiding in line 847. A targetSdkVersion stuck at 33.

These are not bugs. They're checklist items that cost developers days of back-and-forth with review teams. The review cycle typically takes 24-48 hours per attempt. One missing key in Info.plist? That's 2 days wasted.

Guidelint scans your project in seconds and tells you exactly what to fix — in your language.

What makes it different

Feature	Guidelint	Manual review	Other linters
App Store guidelines	✅ 71 rules	❌ Human error	❌ Code-only
Google Play guidelines	✅ 23 rules	❌ Human error	❌ Code-only
Privacy manifest (2024)	✅ Auto-detect	⚠️ Easy to forget	❌ Not supported
AI-ready output	✅ `--format prompt`	❌	❌
Multi-language	✅ EN/TR/DE/NL	❌	❌
Cross-platform	✅ iOS+Android+RN+Flutter	❌ Platform-specific	⚠️ Usually one
Auto-fix	✅ `--fix` flag	❌	⚠️ Limited
Ignore files	✅ `.guidelintignore`	❌	✅
Zero config	✅ `npx guidelint .`	❌	⚠️ Config files
Readiness score	✅ 0-100 with verdict	❌	❌

AI-Ready Output

This is what makes Guidelint different from every other linter.

Run with --format prompt and get a structured markdown report designed to be pasted directly into ChatGPT, Claude, Copilot, or any AI assistant:

guidelint ./MyApp --format prompt | pbcopy

The AI receives:

Full context — project info, platform, scores
Every finding — rule ID, severity, category, file path, guideline reference
A prioritized action plan — step-by-step instructions the AI can follow

## AI Fix Instructions

If you are an AI assistant helping fix these issues, here is a prioritized action plan:

### Step 1: Fix Critical Issues (must fix before submission)

1. **[IOS-PRIV-100]** Create PrivacyInfo.xcprivacy via Xcode > New File > App Privacy
2. **[IOS-PRIV-001]** Add NSCameraUsageDescription to Info.plist → in `Info.plist`
3. **[COM-SEC-001]** Move API key to environment variable → in `NetworkService.swift`

### Step 2: Fix High Severity Issues (strongly recommended)

1. **[IOS-SEC-001]** Remove NSAllowsArbitraryLoads, use NSExceptionDomains → in `Info.plist`
2. **[IOS-IAP-001]** Add Restore Purchases handler and button
3. **[IOS-PRIV-300]** Add in-app account deletion flow
4. **[COM-SEC-002]** Change all URLs to HTTPS → in `NetworkService.swift`
5. **[COM-META-001]** Replace lorem ipsum with real content → in `ViewController.swift`

### Step 3: Review Medium/Low Issues (nice to have)

- **[COM-CRASH-001]** Log errors instead of silently swallowing them
- **[COM-META-003]** Review all TODO/FIXME comments before submission

Paste this into Claude or ChatGPT → it fixes your entire project, file by file, in priority order.

The workflow

1. npx guidelint ./MyApp --format prompt | pbcopy
2. Open ChatGPT/Claude
3. Paste
4. AI fixes everything
5. Run guidelint again to verify
6. Submit to App Store / Google Play

Language Support

Guidelint speaks your language. All findings, fix instructions, and UI labels are fully translated.

Flag	Language	Example
`--lang en`	🇬🇧 English (default)	`guidelint . --lang en`
`--lang tr`	🇹🇷 Türkçe	`guidelint . --lang tr`
`--lang de`	🇩🇪 Deutsch	`guidelint . --lang de`
`--lang nl`	🇳🇱 Nederlands	`guidelint . --lang nl`

Example in Turkish:

  ✗ [IOS-PRIV-100] PrivacyInfo.xcprivacy bulunamadı
    → PrivacyInfo.xcprivacy dosyası eksik. Mayıs 2024'ten itibaren zorunlu.
    → Çözüm: Xcode > New File > iOS > Resource > App Privacy ile oluştur

  SKOR: 57/100 — RİSKLİ — Sorunları gözden geçir

Example in German:

  ✗ [IOS-PRIV-100] PrivacyInfo.xcprivacy nicht gefunden
    → PrivacyInfo.xcprivacy-Datei fehlt. Seit Mai 2024 erforderlich.
    → Lösung: Erstelle über Xcode > New File > iOS > Resource > App Privacy

  BEWERTUNG: 57/100 — RISKANT — Probleme vor dem Einreichen prüfen

Auto-Fix

Run with --fix to automatically correct common issues:

guidelint ./MyApp --fix

  ✓ Auto-fixed 5 issue(s): AND-GRADLE-001, AND-GRADLE-002, AND-GRADLE-003, AND-GRADLE-004, COM-SEC-002

What it fixes:

Issue	Before	After
targetSdkVersion	33	35
compileSdk	33	35
debuggable (release)	true	false
minifyEnabled (release)	false	true
NSAllowsArbitraryLoads	true	false
HTTP URLs	`http://`	`https://`

The tool only fixes safe, deterministic changes. Complex issues still require manual review.

Ignore Files

.guidelintignore

Create a .guidelintignore file in your project root. Same syntax as .gitignore:

# Skip test files
test/**
tests/**
__tests__/**
*.spec.ts
*.test.ts

# Skip vendor code
vendor/**
Pods/**

# Skip generated files
generated/**
*.g.dart

--ignore flag

guidelint ./MyApp --ignore "test/**" "vendor/**" "*.spec.ts"

Supported Platforms

Guidelint auto-detects your project type and runs the right rules.

Platform	How it's detected	Files scanned
iOS — Swift	`.xcodeproj`, `Info.plist`, `*.swift`	`Info.plist`, `PrivacyInfo.xcprivacy`, `*.entitlements`, `Podfile`, `Package.swift`, all `.swift` files
iOS — Objective-C	`.m`, `.h` files	Same as above + `.m`, `.h` files
Android — Kotlin	`AndroidManifest.xml`, `*.kt`	`AndroidManifest.xml`, `build.gradle`, `network_security_config.xml`, `gradle.properties`, all `.kt` files
Android — Java	`AndroidManifest.xml`, `*.java`	Same as above + `.java` files
React Native	`package.json` + `metro.config.*`	Both iOS and Android files + `.js`, `.jsx`, `.ts`, `.tsx`
Flutter	`pubspec.yaml` + `*.dart`	Both iOS and Android files + `.dart`, `pubspec.yaml`

Cross-platform detection

If you have a React Native or Flutter project, Guidelint scans both the ios/ and android/ directories automatically. You get iOS + Android findings in a single run.

Ignored directories

These are automatically excluded from scanning:

node_modules/    build/         dist/          .gradle/
DerivedData/     Pods/          .dart_tool/    .pub-cache/
vendor/          __tests__/     test/          tests/

Rules

Overview

Guidelint ships with 71 rules across 6 categories:

Category	# Rules	Weight	What it covers
🔒 Privacy	23	30%	Usage descriptions, privacy manifest, ATT, tracking, dangerous permissions, background modes
🛡️ Security	14	25%	Hardcoded secrets, HTTP URLs, ATS, cleartext traffic, banned device IDs, signing passwords
⚡ Performance	18	20%	Crash risks, SDK versions, PendingIntent, force unwrap, Hermes, AsyncTask, inlineRequires
🎨 Design	5	10%	Placeholder content, bundle ID, metadata, KeyboardAvoidingView
💰 Business	2	10%	In-App Purchase compliance, restore purchases
⚖️ Legal	3	5%	Account deletion requirement, privacy policy

Platform breakdown

Platform	Rules	Highlights
iOS	27	Privacy manifest, 11 usage descriptions, ATT, StoreKit, background modes, force unwrap
Android	23	targetSdk, 7 dangerous permissions, exported, PendingIntent, signing passwords, arm64
React Native	7	Hermes, Flipper, __DEV__ leak, console.log, bridge deprecation, inlineRequires
Flutter	6	debugPrint, kDebugMode, permission plugins, obfuscation, android:exported
Cross-platform	8	Hardcoded secrets, HTTP URLs, placeholder content, empty catch, sensitive logging

How rules work

Every rule:

Checks a condition — e.g., "Does Info.plist have NSCameraUsageDescription?"
Cross-references with source code — e.g., "Is AVCaptureSession actually used in any .swift file?"
Only fires when both conditions are true — no false positives for unused permissions

This means Guidelint won't flag you for missing NSCameraUsageDescription if your app doesn't use the camera. It understands your actual code.

Scoring

Every project gets a readiness score from 0 to 100, broken down by category.

Severity deductions

Each finding deducts points from its category:

Severity	Points Deducted	Meaning
🔴 Critical	-25	Will definitely cause rejection
🟠 High	-15	Very likely to cause rejection
🟡 Medium	-8	May cause rejection or delays
🔵 Low	-2	Best practice, unlikely to cause rejection
ℹ️ Info	0	Informational only

Category weights

Categories are weighted by their real-world impact on App Store / Google Play review outcomes:

Category	Weight	Why this weight
🔒 Privacy	30%	#1 rejection reason on both stores. Privacy manifest, usage descriptions, ATT — Apple and Google are cracking down hard.
🛡️ Security	25%	Hardcoded secrets and cleartext traffic are instant rejections. Apple's ATS enforcement is strict.
⚡ Performance	20%	Crashes during review = immediate rejection. SDK version requirements are enforced automatically.
🎨 Design	10%	Placeholder content and metadata issues. Less common but still cause rejections.
💰 Business	10%	IAP compliance (Guideline 3.1.1). Missing Restore Purchases is a classic rejection.
⚖️ Legal	5%	Account deletion, privacy policy. Lower weight because these are usually caught early.

Score formula

Overall Score = (Privacy × 0.30) + (Security × 0.25) + (Performance × 0.20)
              + (Design × 0.10) + (Business × 0.10) + (Legal × 0.05)

Verdicts

Score	Verdict	What it means
80–100	✅ Ready	Safe to submit. No critical issues found.
50–79	⚠️ Risky	You might get through, but review the findings first.
0–49	❌ Not Ready	Critical issues detected. Fix them before submitting.

Exit codes

Code	Meaning	Use in CI/CD
`0`	No critical findings	Pipeline passes
`1`	Critical findings exist	Pipeline fails / PR blocked

import { scan, setLocale, translateFindings, formatPrompt } from 'guidelint';

// Set language
setLocale('en');

// Scan
const result = await scan('./MyApp', {
  iosOnly: false,
  androidOnly: false,
  minSeverity: 'low',
});

// Access results
console.log(result.score.overall);      // 72
console.log(result.score.verdict);      // "risky"

Adding a new rule

Rules live in src/rules/. Each rule implements the Rule interface:

import type { Rule } from '../types.js';

const myRule: Rule = {
  id: 'IOS-CUSTOM-001',         // Unique ID: PLATFORM-CATEGORY-NUMBER
  title: 'My custom check',      // Short title (shown in output)
  severity: 'high',              // critical | high | medium | low | info
  category: 'privacy',           // privacy | security | performance | design | business | legal
  platform: 'ios',               // ios | android | both
  guideline: 'Guideline 5.1.1', // Optional: Apple/Google guideline reference
  check(ctx) {
    // ctx.plistRaw       — raw Info.plist XML string
    // ctx.privacyManifestRaw — raw PrivacyInfo.xcprivacy XML string
    // ctx.manifest        — raw AndroidManifest.xml string
    // ctx.buildGradle     — raw build.gradle string
    // ctx.sourceFiles     — array of { path, content, language }
    // ctx.files           — array of { path, name, relativePath, size }

    // Return Finding if issue found, null if OK
    return null;
  },
};

Don't forget to add translations in src/i18n/en.ts, tr.ts, de.ts, nl.ts.
