2,531 PointsError in vend function
Cannot subscript a value of type '[VendingSelection : VendingItem]' with an argument of type '[VendingSelection]'
Here is my code:
class FoodVendingMachine: VendingMachine {
let selection: [VendingSelection] = [.soda, .dietSoda, .chips, .cookie, .sandwich, .wrap, .candyBar, .popTart, .water, .fruitJuice, .sportsDrink, .gum]
var inventory: [VendingSelection : VendingItem]
var amountDeposited: Double = 10.0
required init(inventory: [VendingSelection : VendingItem]) {
self.inventory = inventory
}
func vend( _ quantity: Int, _ slection: VendingSelection) throws {
guard var item = inventory[selection] else {
throw VendingMachineError.invalidSelection
}
}
func deposit(_ amount: Double) {
}
}

3,875 PointsLook at your function vend():
Do you name your local argument correctly? It should be "selection" instead of "slection".
