title: Ionic InAppBrowser on iOS Loading White Blank Screen Error
body: <p>I have been working with InAppBrowser for awhile now and have not run into this issue before. It was loading my URL and now it doesn't seem to want to do so.</p>
  
  <p>First I have imported InAppBroswer properly, it's working 100% on Android. This is an iOS-only issue.</p>
  
  <p>in my config.xml:</p>
  
  <pre><code>&lt;access origin="https://www.mydomain.or/*" /&gt;
  &lt;allow-intent href="*" /&gt;
  &lt;allow-intent href="http://*/*" /&gt;
  &lt;allow-intent href="https://*/*" /&gt;
  &lt;!-- Call to Plugins --&gt;
  &lt;plugin name="cordova-plugin-whitelist" spec="1.3.3" /&gt;
  &lt;plugin name="cordova-plugin-device" spec="2.0.2" /&gt;
  &lt;plugin name="cordova-plugin-splashscreen" spec="5.0.2" /&gt;
  &lt;plugin name="cordova-plugin-ionic-keyboard" spec="2.0.5" /&gt;
  &lt;plugin name="cordova-plugin-inappbrowser" spec="^3.0.0" /&gt;
  &lt;plugin name="cordova-plugin-statusbar" spec="^2.4.2" /&gt;
  &lt;plugin name="cordova-plugin-app-update" spec="^1.6.0" /&gt;
  &lt;plugin name="cordova-plugin-app-version" spec="^0.1.9" /&gt;
  &lt;engine name="android" spec="~7.0.0" /&gt;
  &lt;engine name="ios" spec="~4.5.4" /&gt;
  </code></pre>
  
  <p>My plugins seem to run fine, no lint or compile errors.</p>
  
  <p>I call the browser per their documentation:</p>
  
  <pre><code>//construct the instance of browser we are using to launch with Ionic Native
  const browser = this.iab.create('https://www.mydomain.or', '_blank','location=no');
  //If Browser is Hidden Display
  browser.show();
  </code></pre>
  
  <p>There are NO errors being reported in the console for WKWebView at all, but I get this below image on both simulator and device.

  <p>Steps Taken to Try and resolve this issue are:
  Securty Steps with iOS, WhiteList is added to the Plugins--Please see above plugin list.
  I have added the checks to the plist file:</p>
  
  <pre><code>&lt;key&gt;NSAppTransportSecurity&lt;/key&gt;
  &lt;dict&gt;
    &lt;key&gt;NSExceptionDomains&lt;/key&gt;
    &lt;dict&gt;
      &lt;key&gt;localhost&lt;/key&gt;
      &lt;dict&gt;
        &lt;key&gt;NSExceptionAllowsInsecureHTTPLoads&lt;/key&gt;
        &lt;true/&gt;
      &lt;/dict&gt;
      &lt;key&gt;www.mydomain.or&lt;/key&gt;
      &lt;dict/&gt;
    &lt;/dict&gt;
  &lt;/dict&gt;
  </code></pre>
  
  <p>This has been known to help with similar issues in the past.
  I also added a Meta Tag to my index as this was something that has helped others in the past as well:</p>
  
  <pre><code>&lt;meta http-equiv="Content-Security-Policy" content="default-src 'self'; style-src 'self’; connect-src https://www.mydomain.or; script-src 'self’; media-src *"&gt;
  </code></pre>
  
  <p>This also did not help me out at all. Anyone who may know what the cause of this is would be of great help. I feel like I am at my wits end with this error and want to be able to solve this but know the underlying reason why this is happening as well to avoid it in the future.</p>
  
  <p>Thanks in Advance!</p>
