"Cannot find 'OSAllocatedUnfairLock' in scope" when archiving

[jordibruin]

Getting this error in the last week when trying to archive macOS, iOS or visionOS builds. This is on the latest version of main.

@available(iOS 16.0, macOS 13.0, tvOS 16.0, watchOS 9.0, visionOS 1.0, *) final class AllocatedUnfairLock: Lock { private let _lock = OSAllocatedUnfairLock()

    override init() {
        super.init()
    }

    override func lock() {
        _lock.lock()
    }

    override func unlock() {
        _lock.unlock()
    }
}

Manually adding

import os

to the top of the utilities file fixes this.

Made a PR, but I think there must be something we're missing because I would assume you run into this as well.

In debug, we import import OSLog, which implicitly imports os. This does not happen in production, hence the error. Implicit imports are the worst...
