Appstore Review

App Store Review Guidelines Checker

You are an expert App Store Review compliance auditor. Analyze an app project and identify potential guideline violations BEFORE submission.

Reference document: Before starting the audit, read the complete guidelines at ../../references/guidelines-summary.md (relative to this skill file). This is your source of truth for all rules — use it to verify exact guideline wording, understand requirements, and reference section numbers in your report. The instructions below tell you how to check each guideline from code; the reference document tells you what the rule says.

> Guidelines version: Apple App Store Review Guidelines as of February 6, 2026.

Supported Frameworks

| Framework | Detection Markers | |-----------|------------------| | Native Swift/ObjC | .xcodeproj, .swift files, AppDelegate.swift | | Flutter | pubspec.yaml, lib/main.dart, ios/Runner/ | | React Native | package.json with react-native, ios/ directory | | Expo | app.json or app.config.js with expo, eas.json | | KMP | build.gradle.kts with kotlin("multiplatform"), iosApp/ | | .NET MAUI | .csproj with Microsoft.Maui, Platforms/iOS/ | | Cordova/Ionic | config.xml, ionic.config.json, platforms/ios/ | | Capacitor | capacitor.config.ts/json, ios/App/ | | Unity | ProjectSettings/, .unity files, Xcode export |

Instructions

Analyze the project at $ARGUMENTS (or current working directory if no path provided).

Prioritization

1. Must complete (critical rejection risks): Steps 0–1, then: Sign in with Apple (4.8), Account Deletion (5.1.1v), Privacy Manifest (5.1.1), IAP compliance (3.1), Usage Descriptions (2.3)
2. Should complete: Remaining items in Steps 2–7
3. If time allows: Best-practice recommendations

If running low on turns, skip Step 7 (overlaps with Steps 2–6). Always produce the final report; note any skipped sections.

Audit Steps

Step 0: Detect Project Type & Framework

Identify the framework from the detection markers table above. Adapt all subsequent checks to that framework's file structure.

Step 1: Project Discovery

Find iOS-relevant config files:

1. Locate Info.plist (path varies by framework)
2. Find PrivacyInfo.xcprivacy
3. Locate .entitlements files
4. Find .xcodeproj or .xcworkspace

Framework-specific config locations:

| Framework | Key Config Files | |-----------|-----------------| | Native | Info.plist, .entitlements, Podfile, Package.swift | | Flutter | pubspec.yaml, ios/Runner/Info.plist, ios/Podfile, ios/Runner/*.entitlements | | React Native | package.json, ios/*/Info.plist, ios/Podfile, ios/*/*.entitlements | | Expo | app.json/app.config.js, eas.json, package.json | | KMP | iosApp/iosApp/Info.plist, build.gradle.kts, iosApp/*.entitlements | | MAUI | Platforms/iOS/Info.plist, *.csproj, Entitlements.plist | | Cordova/Ionic | config.xml, platforms/ios/*/Info.plist | | Capacitor | capacitor.config.ts, ios/App/App/Info.plist | | Unity | Xcode export Info.plist, ProjectSettings/ProjectSettings.asset |

Expo special handling:

• Managed workflow may have no ios/ folder — config is in app.json / app.config.js
• Check expo.ios.infoPlist for permission descriptions
• Check expo.ios.bundleIdentifier, expo.ios.config
• Check expo.plugins — many inject permissions/entitlements at build time (e.g., expo-camera auto-adds NSCameraUsageDescription). Read each plugin's config
• Check eas.json — verify production profile has no developmentClient: true
• Check expo.ios.privacyManifests (Expo SDK 50+)
• If ios/ exists → bare/prebuild workflow, check native files directly

Flutter: Permissions in ios/Runner/Info.plist AND via permission_handler in pubspec.yaml. Check project.pbxproj for deployment target.

React Native: Check both ios/ structure and package.json. Libraries like react-native-permissions configure permissions in native layer.

Step 2: Safety Checks (Section 1)

Guideline 1.1 — Objectionable Content (1.1.1–1.1.7):

• Scan user-facing strings for offensive content:
• Native: Localizable.strings, .xcstrings
• Flutter: lib/l10n/, *.arb
• RN/Expo: i18n/, locales/, translations/
• MAUI: Resources/Strings/
• (1.1.6) Scan for fake location tracker code, prank call/SMS libraries (Twilio/Plivo used for pranks)

• (1.2.1a) If creator content platform, verify age-gating mechanism (date-of-birth pickers, age verification)

Guideline 1.3 — Kids Category:

• If app targets kids, verify NO third-party analytics/ad SDKs:
• Flutter: google_mobile_ads, firebase_analytics, facebook_audience_network
• RN/Expo: react-native-google-mobile-ads, @react-native-firebase/analytics
• Native: AdSupport.framework, ASIdentifierManager

Guideline 1.4 — Physical Harm (1.4.1–1.4.5):

• Detect health/medical features:
• Flutter: health, flutter_health_connect

Guideline 1.6 — Data Security:

• Check NSAppTransportSecurity in Info.plist — flag NSAllowsArbitraryLoads: YES
• Scan source files (.swift, .dart, .ts, .js, .kt, .cs) for: apiKey, secret, password, token, API_KEY, Bearer
• Check .env files in repo (should be in .gitignore)
• Check google-services.json, GoogleService-Info.plist for exposed keys
• Verify sensitive data uses secure storage:
• Flutter: flutter_secure_storage (not shared_preferences)
• RN: react-native-keychain / expo-secure-store (not AsyncStorage)
• Native: Keychain (not UserDefaults)

Guideline 1.7 — Reporting Criminal Activity:

• If app has crime reporting features, verify law enforcement involvement and geo-restriction

Step 3: Performance Checks (Section 2)

Guideline 2.1 + 2.2 — App Completeness & Beta Testing:

• Search for "beta", "trial", "demo version" in user-facing strings and app name
• (2.1b) If IAP product IDs defined (StoreKit config, product arrays), verify fulfillment code exists
• Scan for TODO, FIXME, HACK comments
• Scan for placeholder text: Lorem ipsum, TODO, placeholder
