The container CLI tool wraps the underlying Containerization framework, which in turn vends packages for things like EXT4 file system support -- all written in Swift. Here's one example as a jumping off point. https://github.com/apple/containerization/blob/main/Sources/...

You use this construct for unwrapping nullable fields, for example something like this:

guard let httpResult else { return }

Note that you don't need to assign the value to itself in modern Swift. This line takes an optional (httpResult?) and returns early if null. If not, you can use it with strong guarantees that it's not nullable, so no need for ? or ! to unwrap it later in the scope.

One nice thing about this implementation is that it shares many of the same characteristics as Swift on other platforms: unlike some common alternatives, it's not garbage collected but uses reference counting; it uses the same underlying libraries, concurrency primitives and memory model.

Excited to see how folk use it... it's technology that will hopefully springboard some other interesting innovations.

Is it well-maintained or long-neglected? Or am I misunderstanding this?

- How do I enforce that inbound API requests come only from trusted sources?

- How do I enforce fine-grained access to user records?

- How do I enforce a set of naming conventions for a data update?

Many such policies may come from regulatory requirements, may be regional in nature, and may change in otherwise stable codebases. And it's even harder when you're applying this to a highly-scalable production internet service. As a result, defining policy at an organizational level with auditing is a challenge for large enterprises. OPA helps enterprises administer and enforce policies.
