I have a TabView with four tabs they look like this:
For example on Search tab user can search products (presented in a List) and then click on product (simple NavigationLink) to open up more informations (ProductInfoView) about that product (note Search tab will remain selected). 
So my question is:
if user clicks again on Search tab, which is still selected, how can I pop up or dismiss ProductInfoView and return to Search tab?
Facebook has same functionality. Note also that: click on unselected tab will dismiss ProductInfoView and show tab I just selected but clicking again on already selected tab in this case Search while ProductInfoView is open will not do anything.
I have found similar answer here: SwiftUI: How to pop to Root view
Probably I could implement that solution but I didn't find a way how to detect user click on already selected tabItem. I know that UITabBarController has function which probably can do that: 
override func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem) {    
}
Maybe answer is simple but I'm still new in this field and struggling to do this. Thanks in advance.
