Hi, i am developing an iOS App like memorizing english words.
My problem is when the user login on iOS App login screen, the user actually has an UUID, and i cant use this UUID for other story boards,
how can i access this UUID from login page and how can i save the UUID,
our book has an optional in UUID?
when i save this UUID to userDefaults and use it from other story boards, i get nil error, because i can not create UUID in login page, but the backend does.
How can i use user UUID?
