动态结构变量名

Question

I define a struct as follows:

struct MyModel : Decodable {
   var id : Int
   var amount: Int
   let myNewTableId : Int
   let userId : Int 
   let myNewTable : MyNewTable
}

I then use this struct to convert JSON data into an object using JSONDecoder().decode .

The problem is that the myNewTable part of myNewTableId and myNewTable are based on an alias given to the SQL table they originate from. So if the alias is abc the fields should be abcId and abc and if its def it should be defId and def . I've saved this alias into a variable:

let MY_NEW_TABLE_ALIAS = "myNewT"

Is there a way to construct the variable names in the struct dynamically using MY_NEW_TABLE_ALIAS . Ideally, when the alias changes on the SQL side, I just want to update one variable, instead of having to update every single struct which uses that table.

简单的方法是首先将 json 转换为字符串，并用所需的键替换出现次数/使用 CodingKeys 并按原样制作结构，顺便说一句，您不能拥有动态变量名
