Loading images asynchronously in UIKit using Swift is an essential practice to improve the performance of your apps. By fetching images in the background, you can ensure that your UI remains responsive and doesn't freeze while the images are being downloaded.
// Import necessary modules
import UIKit
// Extension to UIImageView for loading images asynchronously
extension UIImageView {
func loadImage(from url: URL) {
DispatchQueue.global().async { [weak self] in
if let data = try? Data(contentsOf: url) {
if let image = UIImage(data: data) {
DispatchQueue.main.async {
self?.image = image
}
}
}
}
}
}
// Usage example
let imageView = UIImageView()
if let imageUrl = URL(string: "https://example.com/image.jpg") {
imageView.loadImage(from: imageUrl)
}
