Push Notifications plugin update not updating iOS build

Hi.

After updating the Phonegap PushPlugin in my ionic project, then
ionic build ios

my iOS build is still using the old plugin. If I platform remove ios then platform add ios if pulls in the new plugin. Is there a way to get the upated plugin into my ios build without removing and adding the entire platform? I was hoping the ‘build ios’ would do it, but it’s not.
