我正在使用合并使用我的API的响应更新我的collectionView，以提供真实的信息。我的API返回工作正常的NSArray，但由于SearchAPI类中的一些奇怪原因，我可以接收响应并在控制台中打印出来**打印（“我们的数组“，searchArray）**但无法接收到我的UIViewController并相应地更新我的collectionView。**print（“value“，value）**Value始终为空

class SearchAPI {
    static let shared = SearchAPI()
    
    func fetchData(url: String, category: String, queryString: String) -> Future<NSArray, Error>{
            var searchArray: NSArray = []
            let urlString = url
            print("url come ", urlString)
            guard let url = URL(string: urlString) else {
                fatalError()
            }
            var request = URLRequest(url: url)
            request.setValue("application/json", forHTTPHeaderField: "Accept")
            request.addValue("application/json", forHTTPHeaderField: "Content-Type")
            request.httpMethod = "GET"
            
            let task = URLSession.shared.dataTask(with: request) { [weak self] data, response, error in
                guard let data = data, error == nil else {

                }

                    if let responseJson = json {
                        searchArray = responseJson
                        print("Our array", searchArray)
