JSONのパースに失敗する
iPhoneアプリを作り始めたのですが、JSONのパースがうまくいかずに非常に困っています。
JSONは下記のような並びになります。
{
"status":"success",
"comments":[
[
{
"comments_id":"12",
"comments_is": true
}
],
[
{
"comments_id":"12",
"comments_is": true
}
]
],
"documents":[
{
"documents_id":"22",
"documents_date":"221",
"share": ["22","19"]
},
{
"documents_id":"22",
"documents_date":"221",
"share": ["22","19"]
}
{
"documents_id":"22",
"documents_date":"221"
}
],
"likes":[
[
{
"liked_id":"42",
"liked_user":"jj"
}
],
[
{
"liked_id":"42",
"liked_user":"jj"
}
],
[
{
"liked_id":"42",
"liked_user":"jj"
}
]
]
}
ネットで調べると主に下記のようなコードが載っているのを見かけましたので試してみましたがなかなかうまくいかず、catchに入ってしまいます。
do {
let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String:AnyObject]
print(json?["documents"] ?? "none")
} catch {
print ("json error")
return
}
ちなみにJSONの並びを「status」や「comments」だけにした場合ですと、下記のコードで取得できました。
do {
let json = try JSONSerialization.jsonObject(with: data, options: []) as? Dictionary<String, AnyObject>
print(json?["status"] ?? "none")
} catch {
print ("json error")
return
}
「documents」は特に全く所得がうまくいきません。
お詳しい方いましたらどうぞよろしくお願いします。

※コード追記しました
上記のJSONコードが手書きで書いたため、正しく文になっていなかったので、実際のJSON文字列をほぼコピペして記載しました。
下記が正しいJSONになります。
