I've been following this article link but the latest version of that plugin is causing several issues and seems to have lots of overhead, Cocoa Pods install etc. We have our own APNS server, I just need the token and to register for notifications.
The plugin I'm using phonegap-plugin-push installs fine but when I open the workspace in XCode I get an error that it can't open my main project because it is open from another project. I only have one instance of XCode running.
Close XCode and reinstall the plug-in.
