Swift FunFacts Help!

I downloaded the project files for the FunFact app to make to compare to my ColorWheel.swift file, because I was getting this error 'UIColor' is not a subtype of NSString' but its still showing the error in the teachers code, please help I'm stuck! :(

you have a function nested inside your randomColor function

func randomColor() -> UIColor {
        func randomFact() -> String {
            var unsignedArrayCount = UInt32(colorsArray.count)
            var unsignedRandomNumber = arc4random_uniform(unsignedArrayCount)
            var randomNumber = Int(unsignedRandomNumber)

        return colorsArray[randomNumber]
    }
}

remove the nested function heading and brackets

func randomColor() -> UIColor {

         var unsignedArrayCount = UInt32(colorsArray.count)
         var unsignedRandomNumber = arc4random_uniform(unsignedArrayCount)
         var randomNumber = Int(unsignedRandomNumber)

        return colorsArray[randomNumber]

}

return colorsArray[randomNumber] ------ !!!'UIColor' is not a subtype of 'NSString'

check the return type of your function. make sure its returning UIColor and not String. Also can you paste in the full function

func randomColor() -> UIColor { func randomFact() -> String { var unsignedArrayCount = UInt32(colorsArray.count) var unsignedRandomNumber = arc4random_uniform(unsignedArrayCount) var randomNumber = Int(unsignedRandomNumber)

    return colorsArray[randomNumber]
}

Thank you, I accidentally copy and pasted that extra function. Oops.
