Privacy Manifest

Privacy Manifest CLI tool parses an Xcode project/workspace or a Swift Package and attempts to locate calls to Apple's required reason APIs ¹ and detect privacy collected data frameworks ².

The tool detects and parses the source files of the project as well as the frameworks added in the Xcode project's Build Phase or in the Swift Package dependencies. It also detects any frameworks / static libraries and checks if they are included in the third-party SDK list that Apple has provided ³.

The tool does not perform any sort of analysis beyond the simple line-by-line check for the existence of the method calls or symbols that Apple has already published.

The tool uses a concurrent queue to speed up the parsing process.

Installation

You can either use the tool by typing: swift run privacy-manifest in the root directory of the project, or you can install the executable to /usr/local/bin directory so that you can call it from any folder.

Check out the project and run the following command in the project root to install the binary to /usr/local/bin.

sudo make install

Usage

After installing the tool to the /usr/local/bin directory, you can invoke it from any directory using the following command:

privacy-manifest analyze --project path/to/project --reveal-occurrences --output path

The path/to/project can be a relative or an absolute path to the .xcodeproj or Package.swift file of your project.

The --reveal-occurrences is an optional flag that displays extended information regarding the occurrences of the required reason APIs / privacy collected data frameworks in your codebase, highlighting the file and the line where a call has been detected.

The --output flag is optional and if specified, a PrivacyInfo.xcprivacy property list file will be generated to that directory based on the detected required reason APIs and from the responses of the user.

Example

Below is the console output from the VLC iOS OSS.

Future implementations

The tool can output the occurrences report to HTML for better readability.

On top of that, the list of third-party crash frameworks can be updated so that it can inform the user when such framework is detected (there is a related TODO in the code).

Disclaimer

Do not use this tool alone to create your privacy manifest file for your app or SDK. You must always double-check the occurrences that the tool displays as the tool does not know whether a certain occurrence is included in a comment or on an unused piece of code. Furthermore, there might also be cases where something has not been included in the parsing process.

This tool gives you a high-level overview of the different required reason APIs and privacy collected data frameworks your project, workspace or package uses, so always do your own research after using this tool, to confirm the findings.
