How to use YouTube API V3?

Question

I'm trying to figure out how to use the new YouTube API (Version 3) in my iOS app but I don't know how to do it. I did many research about it but what I found is all examples and codes for older API so they are not valid. Til now I did understand that for using the new API you have to create a Project in Google Developer Console (and I did it)... but then they send you to a page with some code on it but I really don't understand how to use it. link to google api page What I need to know is how to retrieve some informations from a given URL of a YouTube video, the informations I need are total number of "likes" and total number of "views"... with API 2 it was very simple to do it... but now I really don't know where to begin... Is there someone that please can explain how to achieve this with maybe some examples and some code? I'm pretty sure that a lot of people will benefit from this.

// Swift 3

func search() {


   let videoType = "video you want to search"

    // can use any text


    var dataArray = [[String: AnyObject]]()
    // store videoid , thumbnial , Title , Description

    var apiKey = "_________________"

     // create api key from google developer console for youtube



        var urlString = "https://www.googleapis.com/youtube/v3/search?part=snippet&q=\(videoType)&type=video&videoSyndicated=true&chart=mostPopular&maxResults=10&safeSearch=strict&order=relevance&order=viewCount&type=video&relevanceLanguage=en&regionCode=GB&key=\(apiKey)"



        urlString = urlString.addingPercentEncoding( withAllowedCharacters: .urlQueryAllowed)!
        let targetURL = URL(string: urlString)

        let config = URLSessionConfiguration.default // Session Configuration
        let session = URLSession(configuration: config)

        let task = session.dataTask(with: targetURL!) {

            data, response, error in


            if error != nil {

                print(error!.localizedDescription)


                var alert = UIAlertView(title: "alert", message: "No data.", delegate: nil, cancelButtonTitle: "OK")
                alert.show()



                return

            }

            else {




                do {





                    typealias JSONObject = [String:AnyObject]

                    let  json = try JSONSerialization.jsonObject(with: data!, options: []) as! JSONObject
                    let items  = json["items"] as! Array<JSONObject>



                    for i in 0 ..< items.count {

                        let snippetDictionary = items[i]["snippet"] as! JSONObject
                        print(snippetDictionary)
                        // Initialize a new dictionary and store the data of interest.
                        var youVideoDict = JSONObject()

                        youVideoDict["title"] = snippetDictionary["title"]
                        youVideoDict["channelTitle"] = snippetDictionary["channelTitle"]
                        youVideoDict["thumbnail"] = ((snippetDictionary["thumbnails"] as! JSONObject)["high"] as! JSONObject)["url"]
                        youVideoDict["videoID"] = (items[i]["id"] as! JSONObject)["videoId"]






                        dataArray.append(youVideoDict)


                       print(dataArray)



                        // video like can get by videoID.




                    }


                }

                catch {
                    print("json error: \(error)")
                }

            }
        }
        task.resume()
