Hey Daniel,

firstly note that you're missing the opening curly brace of your init method. You also forgot to initialize the red stored property in the initializer method and make sure to assign the values you give the initializer method as arguments to the stored properties because right now you're hardcoding those values.

Lastly also make sure to write the string in description exactly like the example you can see in the challenge description, so make sure to set the colons correctly and take care of spaces as the challenges can be very picky about this.

This should work:

struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

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

I hope that helps! :)
