以下两种方法的“ Apple合并当量”将是什么？

问题描述

URLSession.shared.dataTaskPublisher（for：>）中有一个与URL会话等效的对象，并且可以很简单地用于处理“错误沙解码”，但是如何处理disableableResult的返回类型呢？ URLSession.shared.dataTaskPublisher（for：>）中有一个与URL Session等效的对象，并且很容易处理“错误沙粒解码”

@discardableResult class func taskForGETRequest<ResponseType: Decodable>(url: URL,responseType: ResponseType.Type,completion: @escaping (ResponseType?,Error?) -> Void) -> URLSessionTask {
