Toast is getting shown behind the view controller

[nishchal-v]

when you show a toast and navigate to another view controller the toast is overshadowed by navigating view controller

[TJRoger]

You should handle this case yourself. e.g. You can hide all toast in that view first before navigating to another view controller,

Just use your UIView's parent.view or even better navigationController?.view (which in most cases will be the same) to render the toast. Then it will stay visible across navigation.
