You can try this new library  JellyGif respects Gif frame duration while being highly CPU  amp  Memory performant  It works great with UITableViewCell  amp  UICollectionViewCell too  To get started you just need to  import JellyGif  let imageView   JellyGifImageView frame  CGRect x  0  y  0  width  100  height  100      Animates Gif from the main bundle imageView startGif with   name  Gif name       Animates Gif with a local path let url   URL string   Gif path    imageView startGif with   localPath url      Animates Gif with data imageView startGif with   data Data     For more information you can look at its README
