Day 16: Not able to see list of strings in console, instead [] is seen

Forums > Swift

I tired to code the exact same thing from day 16, I tried to print the pictures, before it was printing everything in the console! but now when I want to code again, it's printing now a "[ ] " HERE IS MY CODE BELOW

import UIKit

class ViewController: UIViewController { var pictures = [String]()

override func viewDidLoad() {
    super.viewDidLoad()

    let fm = FileManager.default
    let path = Bundle.main.resourcePath!
    let items = try! fm.contentsOfDirectory(atPath: path)

    for item in items {
        //load pic
        if item.hasPrefix("nssl") {
            pictures.append(item)
        }

    }
        print(pictures)
}

}
