Works in xcode but not here?

Why doesn't this code work - it works in xcode?

class Temperature {
    var celsius: Float = 0.0
    var fahrenheit: Float {
        get {
        return (celsius * 1.8) + 32.0
        set {
        celsius = newValue + ((fahrenheit-32)/1.8)

Glad you got that fixed.

Do remember that Xcode will perform tests on your code to make sure it is syntactically correct; that's all.

The Treehouse app will perform those tests on your code plus others that test for the desired outcome of the challenge. So, you can quite easily have code that will work fine in Xcode but fail the Treehouse tests.

For example:

func dayType (day: String) -> String {
    var typeOfDay: String = ""
    for var i = 0; i < daysOfWeek.count; i++ {
        if(day == daysOfWeek[i]){
          // process the array index
            switch i {
                case 0...4: typeOfDay = "It's a weekday"
                case 5, 6: typeOfDay = "It's weekend!"
                default: typeOfDay = "Unlikely to be a day"
            } // end switch
        } //end if
    }// end for
    return typeOfDay
} // end func

This code I just wrote for another forum post will work fine in the Playground. But it'll not help you pass that challenge, ever!!


celsius = ((newValue -32)/1.8) Doh!
