This passes the challenge but doesn't compile.
class TemperatureController: UIViewController {
var temperature: Double {
didSet {
if temperature > 80.0 {
view.backgroundColor = UIColor.red
} else if temperature < 40.0 {
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
}
}

2,998 PointsHi Gabriel do you mean it passed the challenge but doesn't compile in Xcode ? Did you import UIKIt in the Xcode playground ? you would need to to access the items like UIColor in that framework

Thanks so much for your answer. I did indeed import UIKit to a single playground.
Thanks!

2,998 PointsHey Gabriel thats awesome ! I have had that issue before I wasn't sure but it sounded like that was the problem happy to help. Im still wrapping my head around this stuff to but I know that in order to access certain methods and code you have to use frameworks. Happy coding !
