let colorsArrays Is not working! Why?

I have copied the code as what he put down and even checked it with the video but I get errors saying: Use of unresolved identifier 'colorsArray'. I have no idea what to do now.. I am stuck!

struct ColorWheel
{
let colorsArray = [ UIColor(red: 90/255.0, green: 187/255.0, blue: 181/255.0, alpha: 1.0)] //there are more lines of different colors

}

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

var randomNumber = Int(unsignedRandomNumber)

return colorsArray[randomNumber]
}

My problem was not having the function inside the struct.. Silly mistake but fixed!
