I need a SWIFT UI to collect data which is entered in to a CSV file and saved/exported to a flash drive on a iPad running iPadOS 15

For a iPad running iPadOS 15, I need a UI made in SWIFT where a customer’s name can be entered in a text field, and also a stepper where you can enter the number of packages Ex 1 - 5. That data will then be outputted to a CSV file with the current date and a random number. Then the CSV file is saved/exported to a flash drive.

The CSV table would look like:

Package number | Customer Name | Date | ID |
_________________|_________________|_________|___________________|
1 | Company 1 | 10/6/21 | random number |
_________________|_________________|__________|__________________|
2 | Company 1 | 10/6/21 | random number |
_________________|_________________|__________|__________________|

. . . And so on until all packages have an entry that was selected on the stepper
