Error generating IOS application build in IONIC

Question

I’m trying to build an IOS app on Ionic.

I rode in the terminal: ionic cordova build ios --release --prod

But I’m getting:

build-release.xcconfig line 28: Unable to find included file ".. /pods-release.xcconfig"** BUILD FAILED **

I navigated to this build-release.xcconfig file and found on line 28 the following import:

#include "../pods-release.xcconfig"

I searched my project but could not find it. In which process is generated this file?

To install the cocoapods in my project I followed the steps:

I navigated to the Platforms/Ios folder and rode:

sudo gem install cocoapods

pod setup

pod init

pod install

Then I checked the build and had this error of not finding the file...
