Storing Data using CoreData

Hi Guys,
Right now I’m finishing up the registration for my app and during the registration I’m having the user input their first and last name as well as their email. My hope is to take that information and store it using coredata, so that, as can be seen in the screen shot below , i can display it on the users account information page. I’m really struggling as for what i should put for the "text: " part of the text field I’m using to collect this data. Right now I’m using @State variables as placeholders, but I’m wondering what I should do so that I can collect that data and then use it on the “account information” page. I know I repeated myself a lot and this is probably a confusing question, so please suggest anything or ask any clarifying questions. Thanks!
