Get Image Thumbnails from Rumble?

I checked the rumble webpage of the link you provided. I am not sure if there is a smarter/faster way but here is a way to get the thumbnailUrl from their html code.

func getThumbnailFromRumble() {
        let url = URL(string:"")!
        URLSession.shared.dataTask(with: url){ data, response, error in
                guard error == nil else { return }
                guard let httpURLResponse = response as? HTTPURLResponse,
                      httpURLResponse.statusCode == 200,
                      let data = data else {
                    return
                }
                
            let str = String(data: data, encoding: .utf8) // get the htm response as string
            let prefix = "\"thumbnailUrl\":" 
            let suffix = ",\"uploadDate\""   
            
            let matches = str?.match("(\(prefix)(...*)\(suffix))")
            if let thumbnailUrlMatch = matches?.first?.first {
                let thumbnailUrl = thumbnailUrlMatch
                    .replacingOccurrences(of: prefix, with: "") // remove prefix from urlstring
                    .replacingOccurrences(of: suffix, with: "") // remove suffix from urlstring
                    .replacingOccurrences(of: "\"", with: "") // remove escaping characters from urlstring
                
                if let url = URL(string: thumbnailUrl),
                   let data = try? Data(contentsOf: url) {
                    
                     let uiImage = UIImage(data: data)
                     // use the uiimage        
                }
            }
            
        }.resume()
    }

I use this extension to get the necessary string part from the html response

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)) }
        } ?? []
    }
}

Feel free to improve the code.
