在Swift中根据其属性删除数组对象 [英] Removing array object according to its property in Swift

问题描述

我有一个像这样的自定义数组，我想删除学生ID为4的元素

I have a custom array like this and I want to delete the element where Student id is 4

var strNames = [Student(id: 1, name: "ghj"), Student(id: 4, name: "def"), Student(id: 9, name: "bkl")]

我确实喜欢这样.有人可以帮我用Swift方式映射吗?

In classic way I do like this. Can anybody please help me mapping in Swift way?

 var sArray2: [Student] = []
    for item in strNames {
        if item.id != 4 {
            sArray2.append(Student(id: item.id, name: item.name))
        }
    }
strNames = sArray2

推荐答案

您可以使用 RangeReplaceableCollection 变异方法:

mutating func removeAll(where shouldBeRemoved: (Element) throws -> Bool) rethrows

In your case:

strNames.removeAll { $0.id == 4 }
