How do i assign the result to a new variable named taxes?

My code looks like this:

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))
    }
    // add the calculateTaxes method here
    // it should accept only one parameter named 'percentage' of type Double

}

var item = Expense(description: "Hi")
item.amount = 100

item.calculateTaxes(7.5) 

// How do i assign the result to a new variable named taxes???

Edited your post for proper code inclusion (3 backticks before and after code will make it easier to read). Wish I could help with the question!

Daniel,

My Swift skills are very iffy, but where you have:

item.calculateTaxes(7.5)

can you just do:

var taxes = item.calculateTaxes(7.5)

? Seems like it should do the trick.

Just tested this in a playground and it seems to be correct.

Hello Daniel, just a quick question. Which is better in iOS development? Objective C or Swift? Thanks for you answer, I'm just starting in iOS.
