为什么我的 json 格式化字符串没有通过使用 swift 中的 swiftyjson 库转换为 json 数组 3

Question

我正在尝试使用 ios 中的 swift json 将作为字符串响应从服务器获取的以下字符串转换为 json 数组。但它没有被转换成字符串。

这是我的字符串：

这是我的代码：

if let dataFromString = string.data(using: .utf8, allowLossyConversion: false) {

        let json = JSON(data: dataFromString)                                           
        var i=0

        for i in 0..<json.count {    

        }
}

它总是给出 json 计数 0。请帮助。

我终于找到了解决我自己问题的方法。 json 从字符串转换的问题是它包含 \n 字符。由于存在 \n 字符，我用来将字符串转换为 ios 的 Swifty json 库在转换时给我一个错误。我删除了 \n 字符并且它转换没有任何问题。因此，问题是在使用 ios 中的 swifty json 库从字符串转换为 json 格式时删除特殊转义字符，尽管我不知道其他库。
