将图像从S3存储桶下载到UIImageView的更快速的方法

Question

所以目前我在下面使用这个方法（在swift中）从我的S3存储桶中获取图像，这很好用：

static var completionHandler: AWSS3TransferUtilityDownloadCompletionHandlerBlock?
static var MY_BUCKET = "BUCKET_NAME"

let transferUtility = AWSS3TransferUtility.default()

class func downloadFromS3(key: String, completion: @escaping (_ image: UIImage?, _ error: Error?)-> Void){

    let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.USEast1,identityPoolId:POOL_ID)
    let configuration = AWSServiceConfiguration(region:.USEast1, credentialsProvider:credentialsProvider)

    AWSServiceManager.default().defaultServiceConfiguration = configuration
    let transferUtility = AWSS3TransferUtility.default()
    let expression = AWSS3TransferUtilityDownloadExpression()
    transferUtility.downloadData(fromBucket: MY_BUCKET, key: key, expression: expression) { (task, url, data, error) in
        var resultImage: UIImage?
        if let data = data {
            resultImage = UIImage(data: data)
        }
        completion(resultImage, error)
    }

}

唯一的问题是获取图像大约需要5到10秒。是否有更快的方法来获取图像？在Android中，有一个完美的Glide库。是否有像iOS中那样功能的库？
