the innertube api key is hardcoded and we don't know how long it will last so it is recommended to scrap the api key from youtube and set it via XCDYouTubeClient.setInnertubeApiKey

func scrapInnertubeApiKey(){
    let link = "https://www.youtube.com"
    Alamofire.request(link).responseString { (response) in  // network lib https://github.com/Alamofire/Alamofire
        if let html = response.value {
            if let doc = try? HTML(html: html, encoding: .utf8) {   // HTML parser https://github.com/tid-kijyun/Kanna
                if let text = doc.xpath("//script[contains(., 'INNERTUBE_API_KEY')]/text()").first?.text {
                    if let results = text.match("ytcfg.set\\((\\{.*?\\})\\)").last?.last {
                        if let data = results.data(using: .utf8), let model = try? JSONDecoder().decode(InnertubeScrap.self, from: data) {
                            let key = model.INNERTUBE_API_KEY
                            XCDYouTubeClient.setInnertubeApiKey(key)
                        }
                    }
                }
            }
        }
    }
}


struct InnertubeScrap : Codable {
    let INNERTUBE_API_KEY : String
}

extension String {
    func match(_ regex: String) -> [[String]] {
        let nsString = self as NSString
        return (try? NSRegularExpression(pattern: regex, options: []))?.matches(in: self, options: [], range: NSMakeRange(0, nsString.length)).map { match in
            (0..<match.numberOfRanges).map { match.range(at: $0).location == NSNotFound ? "" : nsString.substring(with: match.range(at: $0)) }
        } ?? []
    }
}

Thank you! Worked for me!
Additionally fix extract images from the new response:
In file: XCDYouTubeVideo.m
After line:
NSArray<NSDictionary *> *thumbnails = XCDThumnailArrayWithString(playerResponse);
Add this code:
if((thumbnails==nil || thumbnails.count<1) && info[@"videoDetails"] ) { NSDictionary *videoDetails = info[@"videoDetails"]; if(videoDetails && videoDetails[@"thumbnail"]) { NSDictionary *thumbnail = videoDetails[@"thumbnail"]; if(thumbnail && thumbnail[@"thumbnails"]) { thumbnails = thumbnail[@"thumbnails"]; } } }

Can you give an example of how you work with videos? It's just that I still get an error and I can't do anything about it :(

I pointed my Podfile to your repo pod 'XCDYouTubeKit', git: '[email protected]:armendh/XCDYouTubeKit.git', branch: 'master' and videos work 🙇‍♂️
However, my logs are spammed with the warning on XCDYouTubeVideo.m L:96. Do you know what this is from or how I fix it?

It's not working on my side, anyone found a working solution?

Isn't its private someone's key? I think you shouldn't commit it.
