QML WebView, iOS and self signed ssl certificate

Jan80

Does anyone know how I can make QML WebView (Quick 2) to show a page from a server with a self signed certificate on iOS?

I'am using Qt 5.11.1.

So far I tried:

Installing the certificate in my iPad 6 and enable full trust (see https://support.apple.com/en-us/HT204477)
Set a custom QQMLNetworkAccessManagerFactory in the QMLEngine. But the Factory doesn't get used by WebView, because WebView uses Safari, which is a different process. (See https://bugreports.qt.io/browse/QTBUG-43590)
I tried to set the NSAppTransportSecurity Options in info.plist (see https://stackoverflow.com/questions/32755674/ios9-getting-error-an-ssl-error-has-occurred-and-a-secure-connection-to-the-ser):

	<key>NSAppTransportSecurity</key>
	<dict>
		<key>NSAllowsArbitraryLoads</key>
		<true/>
		<key>NSExceptionDomains</key>
		<dict>
			<key>(mydomain)</key>
			<dict>
				<key>NSExceptionRequiresForwardSecrecy</key>
				<false/>
				<key>NSIncludesSubdomains</key>
				<true/>
				<key>NSExceptionAllowsInsecureHTTPLoads</key>
				<true/>
			</dict>
		</dict>
	</dict>

WebView always fails to load my page with the message "An SSL error has occurred and a secure connection to the server cannot be made."

I can open the page using Safari.
