Answer 1

Localizable.strings uses a key/value pair approach. Do something similar inside your db. Assign a token (key) to your string (value) plus an flag for the language. The "flag" can be a integer, string, what-ever-you-like-most

Then your FetchRequest can query for the token and for the language flag and will return the string that is matching token and flag. When the user changes language the flag is changed, too, And for the same token as previously but now with the new flag a fetch request will return the string for the selected language.
