3,982 PointsIs there anyway that I can solve this with switch statement?
Help! I don't know what is wrong with my code
class TemperatureController: UIViewController {
var temperature: Double{
didSet{
switch self{
case self.temperature < 40:
view.backgroundColor = UIColor.blue
case self.temperature > 80:
view.backgroundColor = UIColor.red
default:
view.backgroundColor = UIColor.green
}
}
}
init(temperature: Double) {
self.temperature = temperature
super.init()
}
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
}
}

54,971 PointsFrom this stack overflow create a new variable:
switch self.temperature {
case let x where x < 40:
view.backgroundColor = UIColor.blue
case let x where x > 80:
view.backgroundColor = UIColor.red
default:
view.backgroundColor = UIColor.green
}
