如何使用Swift对象映射器映射对象的嵌套数组？

import ObjectMapper

// 定义模型对象
class User: Mappable {
    var name: String?
    var age: Int?
    var hobbies: [String]?
    
    required init?(map: Map) {}
    
    func mapping(map: Map) {
        name <- map["name"]
        age <- map["age"]
        hobbies <- (map["hobbies"], ArrayTransform())
    }
}

// 处理嵌套数组的转换器
class ArrayTransform: TransformType {
    typealias Object = [String]
    typealias JSON = [Any]
    
    func transformFromJSON(_ value: Any?) -> [String]? {
        if let array = value as? [String] {
            return array
        }
        return nil
    }
    
    func transformToJSON(_ value: [String]?) -> [Any]? {
        if let array = value {
            return array
        }
        return nil
    }
}

// 执行映射
let json: [String: Any] = [
    "name": "John",
    "age": 25,
    "hobbies": ["reading", "swimming", "coding"]
]

if let user = Mapper<User>().map(JSON: json) {
    print(user.name) // 输出：John
    print(user.age) // 输出：25
    print(user.hobbies) // 输出：["reading", "swimming", "coding"]
}
