How to integrate safeAreaInsets to current constraints extension

I created extension for the view's constraints. You can find the code in the below but after new release iPhone X we need to use safeAreaInsets but i don't know how implement that property. I'll be so glad if you could help me out.

Thanks

    extension UIView {

    func anchor (top: NSLayoutYAxisAnchor?, left: NSLayoutXAxisAnchor?, bottom: NSLayoutYAxisAnchor?, right: NSLayoutXAxisAnchor?,  paddingTop: CGFloat, paddingLeft: CGFloat, paddingBottom: CGFloat, paddingRight: CGFloat, width: CGFloat, height: CGFloat) {
        translatesAutoresizingMaskIntoConstraints = false

        if let top = top {
            self.topAnchor.constraint(equalTo: top, constant: paddingTop).isActive = true
        }
        if let left = left {
            self.leftAnchor.constraint(equalTo: left, constant: paddingLeft).isActive = true
        }
        if let right = right {
            rightAnchor.constraint(equalTo: right, constant: -paddingRight).isActive = true
        }
        if let bottom = bottom {
            bottomAnchor.constraint(equalTo: bottom, constant: -paddingBottom).isActive = true
        }
        if height != 0 {
            heightAnchor.constraint(equalToConstant: height).isActive = true
        }
        if width != 0 {
            widthAnchor.constraint(equalToConstant: width).isActive = true
        }

    }

}

I have refactored your code to take into account the insets. Try the following:

import UIKit

extension UIView {

    func anchor (top: NSLayoutYAxisAnchor?, left: NSLayoutXAxisAnchor?, bottom: NSLayoutYAxisAnchor?, right: NSLayoutXAxisAnchor?,  paddingTop: CGFloat, paddingLeft: CGFloat, paddingBottom: CGFloat, paddingRight: CGFloat, width: CGFloat, height: CGFloat, enableInsets: Bool) {
        var topInset = CGFloat(0)
        var bottomInset = CGFloat(0)
        var rightInset = CGFloat(0)
        var leftInset = CGFloat(0)

        if #available(iOS 11, *), enableInsets {
          let insets = self.safeAreaInsets
          topInset = insets.top
          bottomInset = insets.bottom
          rightInset = insets.right
          leftInset = insets.left
        }

        translatesAutoresizingMaskIntoConstraints = false

        if let top = top {
            self.topAnchor.constraint(equalTo: top, constant: paddingTop+topInset).isActive = true
        }
        if let left = left {
            self.leftAnchor.constraint(equalTo: left, constant: paddingLeft+leftInset).isActive = true
        }
        if let right = right {
            rightAnchor.constraint(equalTo: right, constant: -paddingRight-rightInset).isActive = true
        }
        if let bottom = bottom {
            bottomAnchor.constraint(equalTo: bottom, constant: -paddingBottom-bottomInset).isActive = true
        }
        if height != 0 {
            heightAnchor.constraint(equalToConstant: height).isActive = true
        }
        if width != 0 {
            widthAnchor.constraint(equalToConstant: width).isActive = true
        }

    }

}
