let color = UIColor(argb: 0xFFAABBCC)
let color = UIColor(rgb: 0xAABBCC)

let label = UILabel()
label.fontSize = 15

let button = UIButton()
button.fontSize = 15

@DanielDahan You might wonder why I didn't use Int. As far as I remember, using it was causing crash on 32-bit devices. Even on iPhone 4s simulator for example. I can't verify since I don't have 32bit simulator and won't be able to get it soon. Can you please try it with Int or UInt. With UInt32 it works I am sure. But it will fail to compile with Int32 when a large interger value is used. e.g UIColor(argb: 0xFFFFFFFF)

[daniel-jonathan]

Interesting. Does The reason I believe UInt32 works over Int32 is because UInt32 is unsigned which means all values are positive and it could hold a larger range, where Int32 is signed and therefore holds a smaller positive range but both negative and positive. So please use UInt32.

[OrkhanAlikhanov]

Yeah sure, I know. I meant larger in terms of positivity. Thank you for explaining :)

For the setter and getter, please you use this format:

get {
   return ...
}
set(value) {
   ... = value
}

[OrkhanAlikhanov]

I have to use value or I can use for example size?

[OrkhanAlikhanov]

Does set get order matter?

[daniel-jonathan]

Both order and name matter. As it is consistent with the entire framework. Also, helps to search everything easily when it is the same naming and format.

Thank you!
