I dont understand the error

Hi

Thanks

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

Your code needs to look like this:

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

use newValue instead of fahrenheit.
