Question

将JSON响应映射到模型时遇到一些问题。收到错误后，尽管我从quicktype.io创建了一个模型类，但仍说“类型不匹配”。这是我的模型课。我已经读过很多关于同一标题的问题，但是我找不到任何帮助。

任何人都可以指导我哪里出错或代码的哪一部分出了问题。

Answer 1

您的json响应格式不正确。

"CustomerWalletID": 0000 // this is causing problem
"CustomerWalletID": 0, // try this

参考：-This will show you if your json is valid or not

Answer 2

我猜初始化器有问题，请尝试这种类型的初始化器

required init(from decoder: Decoder) throws {
    let container = try decoder.container(keyedBy: CodingKeys.self)
    self.name = try container.decodeIfPresent(String.self, forKey: .name)
    ...
}

Swift错误：由于格式不正确，无法读取数据
