hi this line giving error:

[coshkun]

fileprivate var width : Int { return ((buttonHeight + spacing) * maxRating) - spacing } tells that: Property 'width' with type 'Int' cannot override a property with type 'CGFloat'

i tried to change return type. this time it compelling about 'we cant override a read only property named width.' you may need to change the name of this property.
