Make sure you're not using the memberwise initializer provided by default?

Don't worry about getting this one wrong; I in fact got a little confused in this challenge earlier today.

The only problems are that:

1. You should take in a description as an argument to the init method.
2. You should set self.red to the argument red, self.blue to the argument blue, etc. Don't set them to a fixed value!
3. I'm not sure if this is causing an error, but if still aren't passing, you should try to remove parentheses around description if you still aren't passing.

I hope this helps. ~Alex

I think the course compiler is throwing errors here where there may be none. The task says this "Using the initializer assign values to the first four properties." Ok so there is an example of this in the Apple docs as follows- ---------------------------------------------quote begins The example below defines a new structure called Fahrenheit to store temperatures expressed in the Fahrenheit scale. The Fahrenheit structure has one stored property, temperature, which is of type Double:

struct Fahrenheit {
    var temperature: Double
    init() {
        temperature = 32.0
    }
}
var f = Fahrenheit()
print("The default temperature is \(f.temperature)° Fahrenheit")
// Prints "The default temperature is 32.0° Fahrenheit"

The structure defines a single initializer, init, with no parameters, which initializes the stored temperature with a value of 32.0 (the freezing point of water in degrees Fahrenheit).

Default Property Values You can set the initial value of a stored property from within an initializer, as shown above. Alternatively, specify a default property value as part of the property’s declaration. You specify a default property value by assigning an initial value to the property when it is defined. ----------------------------------------------quote ends

All pretty clear. So here is the solution

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

    let description: String

    init() {
        self.red = 86.0
        self.green = 191.0
        self.blue = 131.0
        self.alpha = 1.0
        self.description = "red: \(self.red), green: \(self.green), blue: \(self.blue), alpha: \(self.alpha)"
    }
}

Note the empty brackets as part of the init declaration, following the Apple example. My Solution throws an error in the Treehouse task- but not in the preview section. Also if you test it in Xcode with the following

let test = RGBColor()
test.red
test.description

You can go on to test all the values. All as they should be. No errors in Xcode.

ie create an instance called test, then check that the required default values have been set using dot syntax, Xcode then displays the correct and required values on the right.

Ok happy to be corrected, but I have googled the crap out of this and I think this is it. Further- the code is not really displaying correctly here for some Treehousey reason. Pasan- great teacher and communicator, please check this.
