var array = [User]()

var dics = [[String: String?]]()
dics = [
    ["name": "tanaka", "age": "23"],
    ["name": "akane", "age": "24"],
    ["name": "meg", "age": "21"],
    ["name": nil, "age": "25"],
]
var users = dics.map({
    (dic1) -> User in
    var age = dic1["age"]??.toInt()
    return User(name: dic1["name"]!, age: age)
})
users
users[0].name!
users[1].name!
users[2].name!
users[0].age!
users[1].age!
users[2].age!

dic1["age"]??.toInt()とかすごく微妙だ。。
