}
and i want to access all of the data .. for example how to get title inside the snippet? and the default url thumbnails .. and so on ..
if let videos = receivedResponse["items"] as? [[String: Any]] {
for video in videos{
print(video)
}
}
but i don't know how to get the dictionaries inside the array .. how to parse it further and get every and each element in the json?

Answer 1

Define structs that match the data you're getting (https://app.quicktype.io is a great way to jumpstart this), and then use JSONDecoder to parse the data:
struct YoutubeV3 { ... }
let youtubeData = try JSONDecoder().decode(YoutubeV3.self, from: data)
