ios iframe not working on phonegap but its working fine on android phone

My config file

<allow-navigation href="*" />
    <feature name="IntentAndNavigationFilter">
        <param name="ios-package" value="CDVIntentAndNavigationFilter"/>
        <param name="onload" value="true"/>
<gap:plugin name="cordova-plugin-inappbrowser" source="npm" spec="~1.3.0"/>

View file

<iframe ng-src="{{ popup_val | trusted }}" width="100%" height="100%"></iframe>
I have tried all possible ways but not working on iphone and ipad

What is “phonegap” in this context? Normally it is a distribution of Cordova…
