对特定类swift的多维数组进行排序

class Person {
    var name: String
    var age: Int
    
    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }
}

var people: [[Person]] = [
    [Person(name: "John", age: 25), Person(name: "Alice", age: 30)],
    [Person(name: "Bob", age: 20), Person(name: "Charlie", age: 35)],
    [Person(name: "David", age: 28), Person(name: "Eve", age: 22)]
]

// 对多维数组进行排序
people.sort { (array1, array2) -> Bool in
    let age1 = array1.reduce(0) { $0 + $1.age } // 计算每个子数组的年龄总和
    let age2 = array2.reduce(0) { $0 + $1.age }
    return age1 < age2 // 根据年龄总和进行排序
}

// 输出排序结果
for array in people {
    for person in array {
        print("\(person.name) - \(person.age)")
    }
}
