I am working on iCloud Documents syncing and have a toggle between storing locally and on the cloud.
I used this to set this up: http://iaintheindie.com/2014/07/07/icloud-core-data-part-3-complete-stack/
The issue is at some point, there is another store that is created and it becomes the store from which data is pulled. This results in a "loss" of data because it isn't the store where objects were stored/changed. In this case there are 3 stores that are created. Each with a new file path.
