在Swift中循环遍历对象数组

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

let people = [
    Person(name: "Alice", age: 30),
    Person(name: "Bob", age: 25),
    Person(name: "Charlie", age: 35)
]

// 使用for-in循环遍历
for person in people {
    print("Name: \(person.name), Age: \(person.age)")
}

// 使用forEach方法遍历
people.forEach { person in
    print("Name: \(person.name), Age: \(person.age)")
}

if !people.isEmpty {
    for person in people {
        // 执行操作
    }
} else {
    print("数组为空")
}

for person in people {
    if person.age > 30 {
        break
    }
    print("Name: \(person.name), Age: \(person.age)")
}

for (index, person) in people.enumerated() {
    if person.age > 30 {
        people.remove(at: index)
    }
}
