Answer 1

You can try UIRectCorner Document here

here my custom class AGRoundCornersView

extension UIImageView {
    public func roundCorners(_ corners: UIRectCorner, radius: CGFloat) {
        let maskPath = UIBezierPath(roundedRect: bounds,
                                    byRoundingCorners: corners,
                                    cornerRadii: CGSize(width: radius, height: radius))
        let shape = CAShapeLayer()
        shape.path = maskPath.cgPath
        layer.mask = shape
    }
}

code :

1. Call When View is resized.

uiimage.roundCorners([.topLeft, .topRight], radius: 10)

2. Create custom class

class CustomImageView: UIImageView {
    override func layoutSubviews() {
        super.layoutSubviews()
        self.roundCorners([.topLeft, .topRight], radius: 10)
    }
}
