Struct Methods

Help! I am not sure what I am missing.

struct.swift
struct Expense {
    var description: String
    var amount: Double = 0.0

    init (description: String) {
        self.description = description
    }

func calculateTaxes (percentage: Double) -> Double {
  return (self.amount *( percentage/100))
  }

var item = Expense(description: "Charity")
item.amount = 100.0
}

1 Answer

  1. You have to declare the variable outside the struct meaning after the last } .
  2. You should call the calculateTaxes method and pass 7.5 as argument assignint it to a variable called taxes :

var taxes = item.calculateTaxes(7.5)

Hope it helps
