UIWebView reloads video when closing its parent view

Question

I am trying to play a video from my UIWebView and play its audio in the background. This works fine, however when I lock my screen / close out of the view their is a slight delay in sound. The audio goes dead for a split second every time. Why is this happening? Is there a way to access avaudiosession of a UIWebview so I can get more information? Thank you.

Ive tried

• adding all info.plist recommendations

• enabling background mode

• arbitrary loads = true
• avaudiosession.shared().setactive = true

• laying out views if needed

  webView.mediaPlaybackRequiresUserAction = false 
  webView.allowsInlineMediaPlayback = true
  
      webView.loadHTMLString(htmlString, baseURL: URL(string: "https://www.youtube.com"))
  

Answer 1

UIWebview is deprecated in swift 4 so for that you need to use WKWebview in same way. read user guide to use class of WKWebview.
