init(red: Double, green: Double, blue: Double, alpha: Double) { self.red = red self.green = green self.blue=blue self.alpha=alpha self.description = "red:( red), green:( green), blue:( blue), alpha( alpha)"

Treehouse TeacherIt seems like you have an extra space every time you use string interpolation. The correct syntax is \(red)
and not \( red)
. The second one has an extra space in between the opening parentheses and the expression.
