The Swift Container Plugin is a new tool that allows for enhanced containerization on platforms that support it. Despite this advancement, Mac users express frustration over the limited functionality of container and sandboxing technologies on macOS, where features like network namespaces are absent. This missing capability presents notable limitations for developers looking to leverage these technologies fully, especially for tools like Nix that require functional localhost within their sandboxes. Furthermore, while Swift, the programming language behind the plugin, has been around for 11 years, its discussion appears to be dwindling outside of Apple-related conversations, sparking curiosity about its current perception among developers.
