We need an iPhone app that lets employees redeem corporate gift credits. After signing in, the home screen should show the employee’s current credit balance (from our server) and a curated list of available gifts. Tapping a gift opens a detail view with images, description, and price, plus a Redeem button. When Redeem is tapped, create the order with our backend as a single transaction that deducts the item’s price from the user’s balance. On success, show a confirmation and update the balance; on failure, show an error and leave the balance unchanged. Please build the UI in SwiftUI.
