我的数组创建

var arrayOfUsers:UserDetails[] = UserDetails[]()

我的userdetails代码是

struct UserDetails{
    var userName:String
    var userID:String
    var userAge:String
    func userDescription()->String{
        return "name " + userName + "age " + userID
    }
}

我的代码创建对象

for a in 1...1000{
            var user:UserDetails = UserDetails(userName: "name",userID: String(a),userAge: "22")
            arrayOfUsers.append(user)
        }

现在我想过滤arrayOfUsers哪一个有userID“1”。
