"Modify project 1 so that loading the list of NSSL images from our bundle happens in the background"

Am I solving it right? Please answer my questions

Step 1: Move loading into a separate method

Pretty basic

    @objc private func loadPictures() {
        let fm = FileManager.default
        let path = Bundle.main.resourcePath!
        let items = try! fm.contentsOfDirectory(atPath: path)

        for item in items {
            if item.hasPrefix("nssl") {
                pictures.append(item)
            }
        }
        pictures.sort()
    }

Step 2: Add a performSelector to the viewDidLoad()

Pretty obvious too

        performSelector(inBackground: #selector(loadPictures), with: nil)

But

My inner voice start asking questions

• Are we sure that the loading will be finished by the time tableView will start pulling data source methods?
• viewDidLoad() is a place where view is loaded, guns fired, we can move on to the next steps, innit?

If this is the case I have ideas which I can't yet implement unfortunately

1. Move loading to loadView, but this does not make sense becase we will be still blocking UI from loading
2. Ask tableView to not fire loading at initialization and do that after loading completed. How? Ofcourse I can do a second reload, but since I can't even catch that condition on my own device - it may cause only flickering in most general case.
