Save string on icloud in iMessage App

Hi dev, i need an help, i want know if i can implement the storage of the string in icloud database.

I have my imessage app that has a list of string that the user can chose to send but, he can also add a new string to the list.


In this moment i save this list of string on a plist file using an array of string, so i want know if i can save this string on icloud, in this way, the users can use the list of string in all device that he has installed my imessage app and the list will storge on a db and not on a file.


Someone of you can say me if this is possible in an iMessage app, and if there are some documentation that i can read where explane how i can do it?


Thank a lot have a nice day.
