snap shot before applying corner radius to some corner

i code these to get corner radius

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

this is how i am applying radius because i have constrain tooo

import UIKit

class SenderCell: UITableViewCell {

@IBOutlet weak var time: UILabel!
@IBOutlet weak var senderMsg: UILabel!
@IBOutlet weak var backView: UIView!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
    senderMsg.sizeToFit()
}

func setData(reciverTime: String, reciverMsg: String ){
    senderMsg.sizeToFit()
    self.senderMsg.text = reciverMsg
    self.time.text = reciverTime
}

override func  layoutSubviews() {
    backView.roundCorners(corners: [.topRight, .topLeft, .bottomLeft], radius: 5)
}

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}

}

this is. an custom cell for table view

but after doing this is how i am getting radius

what should i do can anyone explain ...

You will have much better results if you use a custom UIView subclass and let it handle its layout.

For example:

class BackView: UIView {
    var corners: UIRectCorner = []
    var radius: CGFloat = 5
    override func layoutSubviews() {
        super.layoutSubviews()
        let path = UIBezierPath(roundedRect: bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
        let mask = CAShapeLayer()
        mask.path = path.cgPath
        layer.mask = mask
    }
}

Then, in Storyboard / Interface Builder, set the Custom Class of the view in your cell to BackView, and connect the @IBOutlet like this:

@IBOutlet var backView: BackView!

Now, in awakeFromNib(), set the corners:

backView.corners = [.topRight, .topLeft, .bottomLeft]
