Steps to share a dictionary between the apple watch (or any app extension app ) and a device. 1) Create a group in the Apple Provisioning Portal. (eg. group.com.mycompany.myapp) 2) Add the group to both apps: the extension and the main app (there is no need to add the group to the actual watch app). 3) Activate the group in the Entitlements.plist for each project (main app and extension)
