Temperature.swift
class Temperature {
    var celsius: Float = 0.0
    var fahrenheit: Float 
    get 
    {
        return fahrenheit
    } 
    set {
    Celsius = (Fahrenheit-32)/1.8))
     }
}

The getter needs to return a value from the first formula given, and the setter needs to use the second formula:

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

Note, in particular, that you cannot use fahrenheit in its own setter. You need to use newValue instead.
