To embed youtube live stream onto your iOS app use the following:

   @IBOutlet weak var LiveStreamViewer: UIWebView!
   let channelID = "[channelID]"

   func loadLiveStream {
        guard
            let youtubeURL = URL(string: "https://www.youtube.com/embed?
                live=1&channel=\(channelID)")
            else { return }
        LiveStreamViewer.loadRequest( URLRequest(url: youtubeURL) )
   }

However, using this will bring up an error within the WebView if you are not actually streaming, and someone tries to play the video. To plan for that add something similar to the following function:

   let googleAPI = "[youtubeAPIKey]"


   func checkLive() {
       let liveChannel = URL(string: "https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=\(channelID)&type=video&eventType=live&key=\(googleAPI)")
       URLSession.shared.dataTask(with:liveChannel!, completionHandler: {(data, response, error) in
           guard let data = data, error == nil else { return }

           do {
               let parsedData = try JSONSerialization.jsonObject(with: data, options: []) as! [String:Any]
               let pageInfo = parsedData["pageInfo"] as! [String:Any]

               print(pageInfo)

               let currentState = pageInfo["totalResults"] as! Int
               print(currentState)

               if currentState == 0 {
                   print("No Stream Right Now")
                   self.LiveStreamViewer.isHidden = true
                   //DO SOMETHING TO LET THEM KNOW YOU ARENT STREAMING
               } else {
                   print("Streaming")
                   self.LiveStreamViewer.isHidden = false
                   self.loadLiveStream()
               }

           } catch let error as NSError {
               print(error)
           }
       }).resume()
   }
