Decodes an image asynchronously and provides a new one for display in views and animations. Facing issues or laggy animations or scrolling of collection view cell like things when loading big images ?

So here is the solution

import UIKit let image = UIImage (named: "big-image") imageView-image = image

import UIKit let image = UIImage(named: "big-image") DispatchQueue.global().async { self.imageView.image = image }// off loading the heavy work to background Now, better approach

import UIKit let image = UIImage (named: "big-image") image?-prepareForDisplay { Iweak selfl preparedImage DispatchQueue.main.async { self?. imageView. image = preparedImage } }

import UIKit let image = UIImage (named: "big-image") Task { imageView image = await image?.byPreparingForDisplay() } You can also create a thumbnail using func prepareThumbnail(of: CGSize, completionHandler: (UIImage?) -> Void) of specific size
