TextField Data Saving

Hey Everyone, I am working on this project and it has to be done really soon. I have 30 TextFields and I need it to be saved to the whole app so If I had 1 phone inputting it, it would sync to another one with the same text value in it. So say I put "Done" in one TextField on Phone 1 then it'll save and update on Phone 2.

Please get back to me when someone can. I have been developing in Xcode for about 7 months now and I am just running into it right now!

Thanks so much
