Integrate privacy into your development process

The session "Integrate privacy into your development process" from WWDC 2025 provides a comprehensive guide on how to incorporate privacy into app development. Here are some key points from the session:

1. Apple's Privacy Philosophy: Apple emphasizes privacy as a fundamental right, focusing on data minimization, on-device processing, transparency, control, and security protections. This philosophy is about not just what can be done with data, but what should be done in the best interests of users.

2. Development Phases: The session outlines integrating privacy into various phases of app development:

   • Planning: Start by defining privacy assurances and aligning them with user intent. This involves setting high-level privacy goals and ensuring they are communicated effectively.
   • Design: Use design principles to educate users about data usage and choices. Set clear expectations and provide meaningful, contextual choices.
   • Development: Implement privacy goals with strong technical foundations. Streamline privacy choices in the user interface and ensure data flows respect user intent.
   • Testing: Conduct tests to ensure privacy assurances are met. This includes unit tests, integration tests, and UI tests to validate privacy controls.
   • Deployment: Prepare privacy nutrition labels and ensure all privacy requirements are met before app deployment.

3. Tools and Technologies: Apple provides various tools to support privacy goals, such as privacy manifests, App Privacy Reports, and Private Access Tokens for anti-fraud measures.

For more detailed guidance on each phase, you can refer to the specific chapters in the session:
