Hello, I have screen with a number of text and image views (cards in a player's hand). After tapping a view (card) 3 times with an .onTapGesture, I remove that view(card) from the array of that player's hand. Then I want to then show the remainder of the text and image views that the player now has in their hand. If I go back to my menu of different navigationlinks and select again that collection of views or cards in the player's hand, it is updated. I am trying to figure out how to 'refresh' without going back to the menu.

Thanks, Kelly

@Kelly is trying thinking procedurally, instead of declaratively!

Declare your Intentions!

Kelly! Remember that SwiftUI is a declarative language. First and foremost, just tell SwiftUI your intentions.

For example:

<< Hey! SwiftUI, I always want to show the user the cards that are in their hand. Always! >>

Now you need to provide the view with a model that represents the cards in your player's hand. If the model has six cards, SwiftUI will display the six cards. If you tap on one card, the .onTapGesture should remove ONE card from your player's hand. How? The code should not try to update the user interface. Instead, the code should just CHANGE THE MODEL.

Change the Model

That is, the model, probably an array of the player's hand will now only have five cards in it. Because the model has been updated, the user interface will invalidate itself and ask SwiftUI to update the PlayerHandView.
