I tried to build the ionic cordova app on xcode, but it shows

 WARN: Ionic Native: tried calling Firebase.getToken, but the Firebase plugin is not installed.
WARN: Install the Firebase plugin: 'ionic cordova plugin add cordova-plugin-firebase'

in the console (build succeed, app can run in my device but the function isn’t working)

attempt 1: If I run reinstall the firebase plugin
ionic cordova plugin rm cordova-plugin-firebase
ionic cordova plugin add cordova-plugin-firebase
it shows build error (build failed in Xcode)
