What's the problem with my answer ?

class TemperatureController: UIViewController { var temperature: Double { didSet{ if temperature > 80 { view.backgroundColor = UIColor.redColor() } if temperature < 40 { view.backgroundColor = UIColor.blueColor() } else { view.backgroundColor = UIColor.greenColor() } } }

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

override func viewDidLoad() {
    view.backgroundColor = UIColor.whiteColor()
}

}

What's is the problem?

It looks like you left out an else:

class TemperatureController: UIViewController { 
  var temperature: Double { 
    didSet { 
      if temperature > 80 { 
         view.backgroundColor = UIColor.redColor()
      } else if temperature < 40 {   //this needs to be else if...
         view.backgroundColor = UIColor.blueColor() 
      } else {
         view.backgroundColor = UIColor.greenColor() 
      } 
    } 
}

oh yes ! thank you
