Geolocation Not working in IOS but working in android

i use Ionic cordova geolocation in IOS and Android both . it works fine android apk . in ios it works fine in ** ionic serve -c** but not working in Apple Test Flight . it’s very frustating please any body give solution

i added
** ```
ionic cordova plugin add cordova-plugin-geolocation --variable GEOLOCATION_USAGE_DESCRIPTION=“To locate you”

then i add info plist in config.xml

**<edit-config file="*-Info.plist" mode="merge" target="NSLocationWhenInUseUsageDescription">
   <string>We use your location for full functionality of certain app features.</string>

also seen this in info plist 

even my app does not ask location permission in prompt 
even i enable location services in mobile
