I have again the error about the compiler. It says that it requires macOS 12, but it's running on macOS 11.x

I think it's an error of the website... could you fix it please?

Thank you Mirko

observer.swift 
class TemperatureController: UIViewController {
    var temperature: Double {
      didSet {
        if (temperature > 80) {
          view.backgroundColor = UIColor.red
        } else if (temperature < 40) {
          view.backgroundColor = UIColor.blue
        } else {
          view.backgroundColor = UIColor.green;
        }
      }
    }

    init(temperature: Double) {
        self.temperature = temperature
        super.init()
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .white
    }
}

Hi Mirko,

I'm not sure I understand?

I copied your code that you posted and pasted into the challenge and it passed, so there seems to be nothing wrong with the challenge or your code.

If you feel there is a technical problem, you should contact the Treehouse Support Team as the Community is mostly just students like you and me.

I hope you get this sorted. :) :dizzy:
