Python Development Techdegree Student 5,771 Pointsset method
Im trying to write a set method for a computed property, the preview tab is telling me "UInt8 is not convertible to 'double'", but every number in my code is already a double and the variables are also set to be doubles, so I do not understand what i have to correct.
class Temperature {
var celsius: Double = 0.0
var fahrenheit: Double {
get { return (celsius * 1.8) + 32.0 }
set { celsius = (fahrenheit-32.0) / 1.8 (newValue) }
}
}

class Temperature {
var celsius: Double=0.0
var fahrenheit: Double {
get {
return (celsius * 1.8) + 32.0
}
set {
celsius = (newValue-32)/1.8
}
}}
The code above should work for this challenge. When using the setter for fahrenheit, the new value has the implicit name newValue. You are using the setter on fahrenheit so it should not be called within the setter.
Hope this helps,
