Finnaly I found a solution:
1 - sudo npm uninstall -g cordova
2 - sudo npm install -g cordova@9.0.0
3 - In config.xml
3.1 - At the end of file add this
<preference name=“WKWebViewOnly” value=“true” />
<feature name=“CDVWKWebViewEngine”>
<param name=“ios-package” value=“CDVWKWebViewEngine” />
</feature>
<preference name=“CordovaWebViewEngine” value=“CDVWKWebViewEngine” />
<preference name=“AllowBackForwardNavigationGestures” value=“true” />
<preference name=“Allow3DTouchLinkPreview” value=“false” />
3.2 Inside <platform name=“ios”> add this
<config-file parent=“GADApplicationIdentifier” target="*-Info.plist">
<string>ca-app-pub-xxxx~xxxxx</string>
</config-file>
<config-file parent=“GADIsAdManagerApp” target="*-Info.plist">
<true />
</config-file>
4 - sudo cordova platform add ios@6.1.1
5 - sudo cordova plugin add https: //github.com/AraHovakimyan/cordova-plugin-wkwebviewxhrfix
6 - cd platforms
7 - sudo chmod -R 777 ios
