According to your comment, this is the solution that you are searching:

1. 使用 SwiftGif 对 UIImage 进行扩展:

1. make an extension of UIImage which uses SwiftGif:

extension UIImage {
  public class func gif(asset: String) -> UIImage? {
    if let asset = NSDataAsset(name: asset) {
       return UIImage.gif(data: asset.data)
    }
    return nil
  }
}

imageView.image = UIImage.gif(asset: "YOUR_GIF_NAME_FROM_ASSET")
