I have a TableView app that plays music. The tracks are named: 0.mp3, 1.mp3 etc. They play in a detail view where I also want an image of the cover. I named the cover images: 0.png, 1.png etc.

I tried to load the correct image with the code:

self.bookImage.image = UIImage(named: ("/\(trackID!).png"))

but it doesn't work.

Here's some more of my code:

import UIKit
import AVFoundation

class AudioPlayerVC: UIViewController {

    var trackID: Int!
    var audioPlayer:AVAudioPlayer!

    @IBOutlet var bookImage: UIImageView! 

    @IBAction func play(_ sender: AnyObject) {
        if !audioPlayer.isPlaying{
            audioPlayer.play()
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        self.bookImage.image = UIImage(named: ("/\(trackID!).png"))
        trackLbl.text = "Track \(trackID!)"

        let path: String! = Bundle.main.resourcePath?.appending("/\(trackID!).mp3")
        let mp3URL = NSURL(fileURLWithPath: path)
        do
        {
            audioPlayer = try AVAudioPlayer(contentsOf: mp3URL as URL)
            audioPlayer.play()
        }
    }
}

You need

self.bookImage.image = UIImage(named:"\(trackID).png")

Or

self.bookImage.image = UIImage(named:"\(trackID)")

Should work just fine.

Everything about Image Lazy loading - what is it, why is it important, how to is put off till the moment the user actually needs to view them. The basic idea of lazy loading is simple - defer loading anything that is not needed right now. Since browser environments and implementation details can vary  Applying the Unsharp Mask filter to a resampled image can help refocus the image details. You can avoid the need for resampling by scanning or creating the image at a sufficiently high resolution. If you want to preview the effects of changing pixel dimensions on‑screen or to print proofs at different resolutions, resample a duplicate of your file.

2) Name images like 0,1,2,3 in Assets.xcassets

Another good practice is to cache the images into the local, once fetched from the web.
