It seems like you're asking about existential containers, but the context provided doesn't directly address this topic. However, I can provide some information on containerization and Swift performance, which were discussed in the sessions from WWDC.
Containerization
In the session titled "Meet Containerization" from WWDC 2025, containerization is introduced as a Swift framework for building containerized applications. It focuses on security, privacy, and performance, allowing developers to package applications and their dependencies into containers. This session covers topics such as image management, container execution, and virtualization. Containers provide runtime isolation and can be managed using command line tools. You can learn more about this in the session Meet Containerization (00:00:48).
Swift Performance
In the session "Explore Swift performance" from WWDC 2024, various low-level principles of Swift performance are discussed, including memory allocation, memory layout, and value copying. The session also covers how Swift handles dynamically-sized types and generics. These topics are crucial for understanding how Swift manages memory and performance, which can be related to how containers manage data. For more details, you can refer to the session Explore Swift performance (00:13:57).
If you have more specific questions about these topics or need further details, feel free to ask!
