Error trying to pass a new value into a variable...

Question

After almost finishing the weather app, i want to convert the temperature that comes in the API to celsius..

Then i did a function in the struct like this:

func convertToCelsius() -> Int {
        let tempToCelsius = ((temperature - 32) * (5/9))
        return tempToCelsius
    }

and then i created this on the init method:

        let teste = currentWeather["temperature"] as Int
        temperature = convertToCelsius(teste)

but it does not work, it says:

"cannot convert the expression's type() to type Int"

Why is that??

Or someone has another way to do this???

Thank you so much...

Your function doesn't allow you to pass a variable to it so you can't pass in then temperature to do your calculation. Let's try this as your function

func convertToCelsius(temperature : Int) -> Int {
    let tempToCelsius = ((temperature - 32) * (5/9))
    return tempToCelsius
}

That should work, but it's still not returning a value, I think it has something to do with 5/9 and converting to integer. But that should solve your first problem.
