Custom NavigationBar in iOS Swift - ios

Question

I'm creating custom navigationbar in swift for every screen. I'm calling this function at viewWillAppear while first time loading it is coming properly if First Time Loading Screen. I move to another screen it is changing. Next View screen navigation title view is shifted. if I came back to previous screen then also it was shiftedenter image description here. I'm unable to find the bug where code was wrong.left and right navigation items are placing fine . But navigationtitle view only getting shifting.
extension UIViewController {
func reightMenuItems(_ isMenuBtn: Bool, _ navigationItem:UINavigationItem) {
if isMenuBtn {
let leftView = UIView()

menuImage.contentMode = .scaleAspectFit
menuImage.frame = CGRect(x: 2.5, y: 6, width: 35, height: 32)
leftView.addSubview(menuImage)

followButton.frame = CGRect(x: 0, y: 0, width: 40, height: 44)

followButton.addTarget(self, action: #selector(self.btnClickMenu), for: .touchUpInside)
