如何在swift的collectionView get中显示s3图片

import AWSS3

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! YourCollectionViewCell
    
    // 设置S3图片的键
    let s3Key = "your_s3_image_key"
    
    // 创建S3GetObjectRequest
    let s3GetObjectRequest = AWSS3GetObjectRequest()
    s3GetObjectRequest?.bucket = "your_s3_bucket_name"
    s3GetObjectRequest?.key = s3Key
    
    // 下载S3图片数据
    AWSS3.default().getObject(s3GetObjectRequest!).continueWith { (task) -> Any? in
        if let error = task.error {
            print("Error downloading S3 object: \(error)")
            return nil
        }
        
        if let data = task.result?.body {
            // 在主线程更新UI
            DispatchQueue.main.async {
                // 将下载的图片数据设置给你的collectionView cell
                cell.imageView.image = UIImage(data: data)
            }
        }
        
        return nil
    }
    
    return cell
}
