App Store Privacy Manifest Analyzer

Features

• Support the analysis of API usage within directories, including Cocoa projects, Flutter projects, and application bundles (.app)
• Scan all source files (including .h, .m, .mm, .c, .cc, .hpp, .cpp, and .swift files) as well as binary files
• Automatically detect missing privacy manifest files and API declarations
• Support for tagging commonly used SDKs
• Provide API usage that could affect your app's privacy manifest

Requirements

• macOS: Xcode Command Line Tools installed

You can try executing the following command to determine if your Mac device supports the script:

xcrun swift -version

If the output after execution resembles the example below:

swift-driver version: 1.90.11.1 Apple Swift version 5.10 (swiftlang-5.10.0.13 clang-1500.3.9.4)

Congratulations! You are now ready to start using the script. Should you encounter any other issues, you can attempt to install Xcode Command Line Tools using the following command:

xcode-select --install

⚠️ 🛠️: When the privacy manifest of third-party SDKs is missing, please update the third-party SDKs or provide feedback to the developers.

If your app's code has the same issue, please refer to the following documents or video for resolution:

• Describing data use in privacy manifests
• Describing use of required reason API
• WWDC2023 - Get started with privacy manifests

🎯: Please promptly update these commonly used SDKs highlighted by the App Store. The complete list is from Upcoming third-party SDK requirements.

🔔: For non-dynamically linked libraries, they are fully copied into the executable file of the application bundle during compilation, which may result in unknown API usage when scanning the executable file of the application.

To pass the App Store review, you need to declare the APIs used by these non-dynamically linked libraries in your app's privacy manifest. You might feel confused as you are not sure where exactly these APIs are being used.

To address this confusion, the analyzer will list API usage that may affect your app's privacy manifest. Pay attention to it, as it will help you fill out the app's privacy manifest more accurately.

2. Command Line Options

• -c: Specify not to filter comments when scanning source code

sh privacy_manifest_analyser.sh -c <directory_path>

It is not recommended to enable this option for the accuracy of API scanning.

• -e: Specify directory to exclude from analysis

sh privacy_manifest_analyser.sh -e <excluded_directory_path> <directory_path>

3. Saving Analysis Logs

sh privacy_manifest_analyser.sh <directory_path> >log.txt

4. More Examples

• ios_example
• flutter_example

Acknowledgements

• The scanning of required reason APIs is implemented based on ios_17_required_reason_api_scanner
