将giphy图像加载到表观中

Question

大家好，所以我试图从GIPHY API加载所有GIF图像，但是我一直在下面遇到错误。

2022-06-09 10:39:12.255202-0700 GIPHY App[41186:1667340] [boringssl] boringssl_metrics_log_metric_block_invoke(153) Failed to log metrics
2022-06-09 10:39:12.356240-0700 GIPHY App[41186:1667113] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__SwiftValue 0x600001ec5020> valueForUndefinedKey:]: this class is not key value coding-compliant for the key url.'

以下是我编写的代码，以尝试使用Alamofire和Alamofireimages将图像加载到表视图中。

import UIKit
import Alamofire
import AlamofireImage

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    
    
    var giphyImage = [GiphyData]()
    
    @IBOutlet weak var giphyTableView: UITableView!
    

    override func viewDidLoad() {
        super.viewDidLoad()
        
        fetchGiphyData()

    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return giphyImage.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! GiphyTableViewCell
        
        let gif: GiphyData
        gif = giphyImage[indexPath.row]
        
        AF.request(gif.url).responseImage { response in
            if let image = response.value {
                cell.giphyImage.image = image
            }
        
                if case .success(let image) = response.result {
                    print("image downloaded: \(image)")
                }
        }
        return cell
    }
    
    func fetchGiphyData() {
    
        let request = AF.request("https://api.giphy.com/v1/gifs/trending?api_key=zONZGFIbbvYDBjLEBlgKxLjbsClfmptw&limit=25&rating=pg-13")
        
        request.responseDecodable(of: GiphyResponseData.self) { (response) in
            guard let gifs = response.value else { return }
            
            let gifImages = [gifs]
            
            for i in 0..<gifImages.count {
                
                self.giphyImage.append(GiphyData(
                    url: ((gifImages[i] as AnyObject).value(forKey: "url") as! String)
                ))
            }
            self.giphyTableView.reloadData()
        }
    }
}

当我解析JSON信息时，我希望从Giphydata结构中获取URL，但也许这不正确？我是自己尝试项目的新手，因此任何建议/帮助都很棒！

import UIKit

struct GiphyResponseData: Codable {
    var data: [ImageInfo]
}

struct ImageInfo: Codable {
    var images: ImageTypes
}

struct ImageTypes: Codable {
    var original: GiphyData
}

struct GiphyData: Codable {
    var url: String
}

谁能告诉我为什么错误会弹出？我从fetchgiphydata函数中获取所需的URL，但表视图没有加载图像。
