2,769 PointsSetting a back ground color based off temperature with a property observer
I don't understand why this challenge is incorrect. I believe I have done everything correctly but it still will not let me pass. It says "make sure to set the back ground color based off the temperature value." Please help, thank you!
class TemperatureController: UIViewController {
var temperature: Double {
didSet {
if temperature > 80.0 {
view.backgroundColor = .red
}
if temperature < 40.0 {
view.backgroundColor = .blue
}
else {
view.backgroundColor = .green
}
}
}
init(temperature: Double) {
self.temperature = temperature
super.init()
}
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
}
}

17,232 PointsThere is just a small mistake, you forgot an "else". It should read:
{
didSet {
if temperature > 80.0 {
view.backgroundColor = .red
}
else if temperature < 40.0 {
view.backgroundColor = .blue
}
else {
view.backgroundColor = .green
}
}
}
