设置Navigationview：

.navigationBarBackButtonHidden(true)
.toolbar {
            ToolbarItem(placement: .navigationBarLeading) {
                Button {
                    self.presentationMode.wrappedValue.dismiss()
                    CoscoPlayer.shareInstance.destroy()
                } label: {
                    Image(systemName: "chevron.backward")
                        .resizable()
                        .aspectRatio(contentMode: .fit)
                        .frame(width: 20, height: 20, alignment: .leading)
                        .tint(AppColor.black)
                }

            }
        }

扩展UINavigationController实现侧滑返回:

extension UINavigationController: UIGestureRecognizerDelegate {
    override open func viewDidLoad() {
        super.viewDidLoad()
        interactivePopGestureRecognizer?.delegate = self
    }
    public func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
        return viewControllers.count > 1
    }
}
