To display images with placeholders and caching in Swift, you might want to use a popular library like SDWebImage or you can implement your own caching logic. This ensures that images load efficiently and placeholder images are shown while the main images are being fetched.

This guide covers how to effectively use image placeholders and implement caching for images in Swift applications. It explores different libraries and methods to achieve this.
// Example using SDWebImage for image loading with a placeholder
import UIKit
import SDWebImage
class ViewController: UIViewController {
@IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
let imageURL = URL(string: "https://example.com/myimage.jpg")
let placeholderImage = UIImage(named: "placeholder.png")
imageView.sd_setImage(with: imageURL, placeholderImage: placeholderImage, options: .highPriority, completed: nil)
}
}
