[swift]ネストしたDictionaryの取得

初歩的だが備忘録てきにメモ

dictionary: {
    email = "aaa@a.a";
    "first_name" = hoge;
    id = xxxxxxxxxxxxxxxxxx;
    "last_name" = hoge;
    name = "hoge hoge";
    picture =     {
        data =         {
            height = 200;
            "is_silhouette" = 0;
            url = "https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
            width = 200;
        };
    };
}

こんなDictionaryがあってpicture>data>urlが欲しかったら

let url = dictionary.value(forKeyPath: "picture.data.url")

で取得
