I've added a frame with youtube video in WebView. It works fine:

webView.loadHTMLString("<html><head><title>.</title><style>body,html,iframe{margin:0;padding:0;}</style></head><body>
<iframe width=\"" + String(describing: w) + "\" height=\"" + String(describing: h) + "\" src=\"" + livestream.Url + "?&playinline=1\" frameborder=\"0\" allowfullscreen></iframe></body></html>", baseURL: nil)

Then I did the same for livestream.com video. I got these errors:

CFNetwork SSLHandshake failed (-9806)
SURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9806)
Received memory warning.

I also added data in Info.plist file:

<dict>

     <key>NSAllowsArbitraryLoads</key>

      <true/>

      <key>NSExceptionDomains</key>

      <dict>

           <key>livestream.com</key>

           <dict>

                <key>NSIncludesSubdomains</key>

                <true/>

                <key>NSExceptionAllowsInsecureHTTPLoads</key>

                <true/>

                <key>NSExceptionMinimumTLSVersion</key>

                <string>TLSv1.1</string>

           </dict>

      </dict>

</dict>

CFNetwork SSLHandshake failed (-9806)
SURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9806)

In these TLS errors, what was the actual URL?

I also added data in Info.plist file:

If you want to eliminate ATS from the equation, use an

Info.plist

that only has

NSAllowsArbitraryLoads

. Using both

NSAllowsArbitraryLoads

and

NSExceptionDomains

just muddies the waters.

Actual URL is:

https://livestream.com/accounts/11528772/events/6482773/videos/139217199

I use it in iframe at WebView:

Could you add this iframe in your WebView? I think you will have the same error:

CFNetwork SSLHandshake failed (-9806)
SURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9806)
Received memory warning.

Could you add this iframe in your WebView?

I gave that a try. Here’s the code I used:

let html = """
<iframe id="ls_embed_1516895384" src="http://livestream.com/accounts/11528772/events/6482773/videos/139217199/player?width=640&height=360&enableInfo=true&defaultDrawer=&autoPlay=true&mute=false" width="640" height="360" frameborder="0" scrolling="no" allowfullscreen> </iframe>
"""

@IBAction func testAction(_ sender: AnyObject) {
    self.webView.loadHTMLString(self.html, baseURL: nil)
}

where

self.webView

is a

WKWebView

set up with the default configuration. It worked just fine for me (tested on a device running iOS 11.2.2). And by “worked”, I mean:

I saw a video UI.
Tapping on its play button lead to playing video.

btw The error you’re seeing, -9806, is defined as

errSSLClosedAbort

. This has a lot of potential causes, but they’re all caused by the TLS stack getting something unexpected in from the ‘wire’.

ps I just noticed you mentioned

UIWebView

in the subject line, so I retried my test with

UIWebView

and also didn’t see the problem. Realistically though, you should be using

WKWebView

unless you have some compelling reason to stick with a web view that’s effectively, although not officially, deprecated.
