Challenge Task 1 of 2
Let's get some practice working with views and colors! In the editor below you have a view controller subclass.
Add a stored property to the view controller named blueColor and assign an instance of UIColor as the default value.
You can use UIColor's RGB initializer method and pass the values 0,0,255,1.0 for red, green, blue and alpha respectively. Alternatively, UIColor has a convenience method that you can use: UIColor.blueColor().

class ViewController: UIViewController {
let blueColor = [
UIColor(red: 0, green: 0, blue: 255/255.0, alpha: 1.0)
]
view.UIColor.blueColor()
override func viewDidLoad() {
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
// Dispose of any resources that can be recreated
}
}

I think I have your solution. Try this.
class ViewController: UIViewController {
let blueColor = UIColor(red: 0, green: 0, blue: 255, alpha: 1.0)
override func viewDidLoad() {
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
// Dispose of any resources that can be recreated
}
}
