Folio Image Pipeline is an image loading and caching framework for iOS clients
Usage
let imagePipeline = ImagePipeline()
imagePipeline.shared.load(/* image URL */, into: /* image view */, transition: .fadeIn /* default is `.none`*/,
defaultImage: ..., failureImage: ...)Example
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! Cell
ImagePipeline.shared.load(urls[indexPath.row % 200],
into: cell.imageView,
transition: .fadeIn,
defaultImage: UIImage(named: "loading")!,
failureImage: UIImage(named: "failed")!)
return cell
}Resize
Aspect Fit (Default)
let resizer = ImageResizer(targetSize: CGSize(width: 400, height: 400))
ImagePipeline.shared.load(/* imageURL */, into: /* image view */, processors: [resizer])| Original | Resized |

let scale: CGFloat = 2
let size = CGSize(width: 375 * scale, height: 232 * scale)
let resizer = ImageResizer(targetSize: size, contentMode: .aspectFill)
let filter = BlurFilter(style: .light)
ImagePipeline.shared.load(/* imageURL */, into: /* image view */, processors: [resizer, filter])| Original | Blurred |
