  • Reduce opportunities for an attacker to target your app through its extensions.

    Separating sensitive calculations, such as handling data from untrusted sources, into extensions that the system runs as separate processes from your app reduces the opportunity for attackers to target the sensitive calculation and gain access to other parts of your app or the system. Create enhanced security extensions on iOS, iPadOS, and macOS to enforce tighter sandbox restrictions, and enable compiler and runtime security protections.
