Ok thanks for information. Yes it would be better if we use Ionic service to build project.
I didn’t post the answer of support here, but there it is :
You’re seeing these errors because currently the Package service in Ionic Pro does not currently have support for CocoaPods. If your app includes plugins that require CocoaPods, you would need to instead run builds in a local environment with CocoaPods installed.
We have an open improvement ticket to add CocoaPods support, and we’re keeping close track on user demand. I’ll add your request to that ticket.
