ProcessInfo.init() is public on Darwin but internal on Linux

[Kyle-Ye]

On Apple platforms, ProcessInfo inherits from NSObject, and as a result, the default init() initializer is automatically inferred as public.

However, on non-Apple platforms (e.g. Linux), ProcessInfo does not inherit from NSObject, and init() is inferred as internal. This leads to platform inconsistency in the following code:

let info = ProcessInfo()

This compiles successfully on Darwin platforms, but fails to compile on Linux with the error:

error: 'init' is inaccessible due to 'internal' protection level

I would like to ask:

• Is this considered a platform inconsistency that needs to be aligned/fixed?
• Or is it expected that ProcessInfo() is not a supported construction pattern, and the correct usage should always be ProcessInfo.processInfo singleton?

Thank you for your clarification and guidance.

FWIW, I once had a similar question about FileHandle: SR-11926.
Guessing from the answer I got there, ProcessInfo.init has no choice but to be open on Darwin owing to Objective-C feature; even if that's not desirable?
