Designating switch to record Xcode iOS - ios

Question

Hi all,
I am trying to build an app for my school project that I am building on Xcode for iOS. The app involves the user being able to save information about their bills. This data is string data and includes the potential for the user being able to save the name of a bill and when the bill was received. I want it that if the bill is related to a specific expenses, for that data to be saved to a specific record that holds data for that specific expense. For example, if the user received a bill for their car, they would enter the bill details and that data could be saved to one specific record that holds all car expense bill data. The way the user could specify where they want to data to go too is through switching on the relevant switch. I am not sure how I can get it that when the user turns on, for example car, that the data will save to that record. Could you please help?
I have included my code and the photo of my interface.
Thank you

Answer 1

If you want to segregate expenses based on type of expenses, have enum of "expenseType" something like below.
enum ExpenseType{
case Car
case Telephone
case Grossary
case Misc
}
Have a single expense object in which mention "expenseType" as attribute. Based on user selection of switch add that expense to corresponding record.
In this case you should not allow user to select more than one switch.
