Description

I want a clear API for my class so I've marked initializer with @discardableResult if I only need to watch one directory for events. Only on the next morning (Yes, I've coded this at night 😅) I've realized that this code can only work if there a retain cycle. So I've try to dig into memory graph, but I don't find any retain cycles, only kevents pointing to my class.

It's strange because they should disappear as soon as all directory files is no longer watched - but they don't. Main problem that I see here is that all watched files possibly will never be closed (because classes deinit is never called) and it's definitely not good for memory usage.

deinit {
    close(kernelQueue)
    closeWatched()
}

private func closeWatched() {
    // keys here is files descriptors 
    watchedFiles.keys.forEach { closeFile($0) }
    close(watchedDirectory)    
}
