Vitamin provides you with the VitaminRadius enum, which has eight possible cases:
.radius100.radius200.radius300.radius400.radius500.radius600.radius700.radius800
To apply a radius to any view, you have to attribute the rawValue of the desired enum case to the .layer.cornerRadius property of your view
import Vitamin
let label = UILabel(
frame: CGRect(
origin: .zero,
size: CGSize(width: 200, height: 100)
)
)
label.text = "Test label"
label.layer.backgroundColor = VitaminColor.Core.Background.primary.cgColor
label.layer.borderColor = VitaminColor.Core.Border.primary.cgColor
label.layer.borderWidth = 1.0
label.backgroundColor = .clear
// This label will have a rounded border with a corner radius of 16px
label.layer.cornerRadius = VitaminRadius.radius400.rawValue
