Xamarin forms web view redirect failing - xamarin.forms

Question

Got an iOS issue with my XamForms web view. I have set the info.plist to allow NSAllowsArbitraryLoads
My URL is https://myurl.co.uk//rewards.html?sso=<GUID>&cid=<ID> - nothing out of the ordinary. When I hit go on Safari as a direct link (I type it in), the URL shows. No such luck on the Xamarin form view. Here I get the following throwback

2019-11-21 10:28:59.523851+0000 Perks.iOS[44969:1429290] NSURLConnection finished with error - code -1003
Any ideas on what is causing the issue? When I put the URL through postman, there is some JS on the redirected page, but it's not getting that far, so I'm guessing it's the web view at fault

Answer 1

Cause: Since iOS 9, iOS will only allow your application to communicate with servers that implement best-practice security by default. Values must be set in Info.plist to enable communication with insecure servers.
Solution: Add the following code in your info.plist to trust your domain.
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>myurl.co.uk</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
</dict>
