根据条件Swift获取模型obj的特定属性数组

struct Person {
    var name: String
    var age: Int
    var gender: String
}

func getSpecificProperties<T>(from obj: T, properties: (T) -> Any) -> [Any] {
    let mirror = Mirror(reflecting: obj)
    var result: [Any] = []
    
    for child in mirror.children {
        if let property = properties(child.value as! T) as? Any {
            result.append(property)
        }
    }
    
    return result
}

let person = Person(name: "John", age: 30, gender: "Male")
let names = getSpecificProperties(from: person) { $0.name }
print(names) // 输出: ["John"]

let ages = getSpecificProperties(from: person) { $0.age }
print(ages) // 输出: [30]
