The session "Meet Containerization" at WWDC 2025 introduces a new open-source Swift framework for building containerized applications. This framework focuses on security, privacy, and performance, and is designed to work with Linux containers. The session covers the basics of containers, their use cases, and the APIs provided by the containerization framework. It also explores a command-line tool for managing containers.
Containers are used to isolate workloads from the host machine and from each other, allowing developers to package applications with their dependencies into a single deployable unit. This isolation includes an isolated network stack for privacy and the ability to allocate resources like CPU, memory, and disk based on workload needs.
For more details, you can check out the session Meet Containerization (00:00:00) which provides an introduction to the framework and its capabilities.
