Vendingmachine.swift file is incorrect. Please help me out

Right at the end I have two placeholers. Missed out on that one.

Can someone explain to me what I need to put insider those funcs ?

class FoodVendingMachine: VendingMachine { let selection: [VendingSelection] = [.soda, .dietSoda, .chips, .cookie, .wrap, .sandwich, .candyBar, .popTart , .water, .fruitJuice, .sportsDrink, .gum ] quantity von z.b. .chips entspricht var inventory: [VendingSelection : VendingItem] var amountDeposited: Double = 10.0 // Startguthaben der User

the keyword "required" required init(inventory: [VendingSelection : VendingItem]) { self.inventory = inventory } func vend(_ quantity: Int, _ selection: VendingSelection) throws { <#code#> } func deposit(_ amount: Double) { <#code#> } }
