"items"、 "snippet"のすべての "title"を出力したいのですが、何らかの理由でforループが実行されていません。誰かが私を助けることができたら、事前に感謝します。Swift 3でYouTubeチャンネルの動画タイトルのリストを印刷するにはどうすればよいですか？
コード：
let url = URL(string: "https://www.googleapis.com/youtube/v3/search?key=\(key)&channelId=\(channelID)&part=snippet,id&order=date&maxResults=20")
let task = URLSession.shared.dataTask(with: url!) { (data, response, error) in
if error != nil {
print("ERROR")
} else {
if let content = data {
do {
let json = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
print(json)
for _ in json as! [String: AnyObject] {
if let items = json["items"] as? NSDictionary {
print(items)
if let snippet = items["snippet"] as? NSDictionary {
print(snippet)
if let title = snippet["title"] as? NSDictionary {
print(title)
}
}
}
}
} catch {
print("ERROR")
}
}
}
}
task.resume()
私はGoogleからの受信リミット - 側があるので、JSON -Iは、それはたくさん短くです：
