ios - 如何将 [JSON] 转换为数据格式（编码），以便我可以将它与我的模型绑定

Question

我有 [JSON] 数组格式的数据，我需要基于 JSON 创建模型并需要绑定它们

我尝试对 [JSON] 进行编码，但应用程序崩溃并显示错误消息

由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“JSON 写入中的类型无效 (__SwiftValue)”

 func getDataForTzlState(m_Tzlstates: [JSON]) {
    do {
       let jsonEncoder = JSONEncoder()
        jsonEncoder.outputFormatting = .prettyPrinted
        let jsonData = try? jsonEncoder.encode(m_Tzlstates)
        guard let data = jsonData else {return}
        let tzlstate = try JSONDecoder().decode(Tzlstate.self, from: data)
       print(tzlstate)
    } catch {
        print(error.localizedDescription)
    }
}

我创建了一个基于 JSON 数据的模型，并希望将它们与 [JSON] 数组值绑定

JSON是

基于模型的结构
