iOS Object-Oriented Swift Properties Computed Properties

Assume you are creating a Weather app and are provided the temperature in Celsius. We need to create a read-only compute

i'm having trouble understanding this question. If someone could help me with this it would be awesome.

Temperature.swift
class Temperature {
    var celsius: Float = 0.0

var Fahrenheit : Float {
return celcius * 1.8 + 32
}

}

You are almost there. For one, you have misspelled celsius. Computed properties differ from stores properties in that they do not actually store a value directly. Your code should look like this:

class Temperature {
    var celsius: Float = 0.0
    var fahrenheit: Float {
      return (celsius * 1.8) + 32
    }
}

I can see you understand this based upon how close you were to the correct answer.
