Using UIBezierPath:byRoundingCorners: with Swift 2 and Swift 3
Swift 2:
let buttonPath = UIBezierPath(roundedRect: button.bounds, byRoundingCorners: [.TopLeft , .BottomLeft], cornerRadii: CGSizeMake(1.0, 1.0))Swift 3 and Swift 4:
let buttonPath = UIBezierPath(roundedRect: button.bounds, byRoundingCorners: [.topLeft ,.bottomLeft], cornerRadii: CGSize(width:1.0, height:1.0))
In this case in swift 2.0 is required to make union of two corners. F. ex.:
let corners = UIRectCorner.TopLeft.union(UIRectCorner.BottomLeft)let buttonPath = UIBezierPath(roundedRect: button.bounds, byRoundingCorners: corners, cornerRadii: CGSizeMake(1.0, 1.0))Works with Swift 2 and Swift 3
