Make user defined attributes apply the CGColor datatype in iOS
1 min readOct 3, 2020
By default, Interface Builder doesn’t accept the CGColor datatype, so to allow adding a CGColor using user defined attributes in interface builder; one may want to use an extension like this:
Swift Extension :
extension CALayer {
func borderUIColor() -> UIColor? {return borderColor != nil ? UIColor(CGColor: borderColor!) : nil
}func setBorderUIColor(color: UIColor) {
borderColor = color.CGColor }
}
The new user defined attribute (borderUIColor) will be recognized and applied without problems.
