Trying to return a computed property that calculates fahrenheit using an input of celcius..think the error is in my sum

Think the error is in the celcius sum... as its not compiling. Or have i misunderstood the question?

Temperature.swift
class Temperature {

    var celsius: Float = 0.0

    var fahrenheit: Float {
      return (celcius * 1.8 ) + 32))
}

}

You misspelled celsius in the return statement. And you don't need parentheses, Swift will calculate in that order by default, but the challenges can be picky so it might need them, even though its correct without.

But yeh, celsius is misspelled.

Thats the nature of coding, you have to be super careful about tiny spelling mistakes, even a missing " or something, or a missing ) somewhere will utterly destroy your code and it can take hours to figure out you left off a / in the string of a URL request.

Looks like you've got your parentheses a little messed up. Try this:

return ((celsius * 1.8) + 32)

Hope this helps!
