The formula for Fahrenheit to Celsius is; Celsius = (Fahrenheit - 32) * (5/9)

// You could create a "helper method" to compute the value.
func fahrenheitToCelsius(fahrenheit: Double) -> Double {
      return (fahrenheit - 32) * 5 / 9

Thanks a lot

Used the formula in my build a weather app and it works:

if let temperature = currentWeather.temperature {

                    let celsius = (temperature - 32) * 5 / 9

                    self.currentTemperaturLabel?.text = "\(celsius)ΒΊ"
