这是json的作品，但我面对的是＃34;无法转换类型＆＃39; NSData＆＃39;输入＆＃39;日期＆＃39;在胁迫中＃34;我怎么解决我正在考虑日期参数

的这个错误

Answer 1

1-替换此

 let jsonObject = try JSONSerialization.jsonObject(with: data as Date, options: .allowFragments)

与

 let jsonObject = try JSONSerialization.jsonObject(with: data as Data, options: .allowFragments)

它是Data对象而不是Date

2-不需要片段

 let jsonObject = try JSONSerialization.jsonObject(with: data as Data, options: [])

if let object = jsonObject as? [NSString: Any]

3-这一行

 let data = NSData(contentsOf: url)

阻止主线程考虑使用URLSession或Alamofire

无法转换类型＆＃39; NSData＆＃39;的值输入＆＃39;日期＆＃39;在json工作中受到胁迫？
