Question

如何统计团队A中的teamMember？

class BasketBallTeam {
    var teamName: String
    var teamMember: [String]

    init(teamName: String, teamMember: [String]) {
        self.teamName = teamName
        self.teamMember = teamMember
    }
}

let highSchoolTeam: [BasketBallTeam] = [
    BasketBallTeam(teamName: "A", teamMember: [
        "John", "Sam", "Tom", "Ricky", "George"
    ]),
    BasketBallTeam(teamName: "B", teamMember: [
        "Jason", "Michael", "Daniel", "Henry", "David", "Luke"
    ]),
]

Answer 1

只需计数即可。

由于highSchoolTeam 是一个数组，您必须获取第一个 项

let numberOfMembers = highSchoolTeam.first?.teamMember.count

请以复数形式命名teamMemberteamMembers(甚至members)来表示数组
