You seem to be trying to convert a Float into a Double, which will trigger an error in Swift.

class Temperature {
    var celsius: Float = 0.0

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

The casing for celsius is also not the same

One other thing to mention is fahrenheit was spelled wrong, the h was missing at the start.
