For any developers who are at #WWDC26 - come join us in the Privacy & Security Labs after SOTU!
Agentic tools and features introduce new categories of security risks and vulnerabilities. My team, and one of our partner teams, has put together this superb #WWDC26 session to help developers mitigate these risks - using what we learned while securing Siri AI

Apple and Google collaborate with the GSMA to roll out end-to-end encrypted RCS messaging in beta, enhancing cross-platform communication security.
Alongside the next generation of Apple Intelligence, today we’re expanding Private Cloud Compute (PCC) beyond Apple’s data centers. When Apple introduced Private Cloud Compute in 2024, we defined a new frontier for private AI inference, extending the security and privacy of Apple devices into the cloud for those AI workloads more complex than on-device models can handle. Now, we are collaborating with Google and NVIDIA to run new Apple Intelligence workloads on Google Cloud Platform, extending our industry-leading PCC privacy commitments to third-party data centers for the first time.
Learn to bolster your app’s security and help protect user data in this online activity streaming from the Apple Developer Center Cupertino. Whether you’re hardening an existing app or starting a new project, you’ll learn directly from Apple engineers about how to reinforce your app from the ground up.
Learn about the security challenges facing modern apps, and explore a comprehensive suite of tools and technologies designed to help safeguard user data. Discover how you can protect your C and C++ codebases with powerful features like Memory Integrity Enforcement, pointer authentication, and memory bounds safety. Find out how to adopt Swift for your most security-sensitive components, taking advantage of its inherent safety and modern abstractions to write secure, high-performance code. And get guidance on building a clear security roadmap for new and existing projects, from high-level strategy to hands-on implementation.
Presentations:
Enhance app security with Xcode
Protect your app from memory safety vulnerabilities
Implement performance-tuned Memory Integrity Enforcement
Control flow integrity with Pointer Authentication
