My case is simple - tap or double tap. Code below adds a gesture recognizer to each item index in the ForEach loop of a basic List (no Nav wrapper). It returns a single Tap properly but on a double tap it returns both the 1st the double tap then the single tap. It seems I need something more like .exclusiveGesture but there is none. Any suggestions appreciated (I have a wasteful workaround using an otherwise needed State bool to avoid taking the second action)

I need exclusivity for taps (.exclusiveGesture would be just right if there were one) Thanks for any pointers.

DefaultRowView(row: model.displayedStore[index], onDisplayedList: true)
.gesture(
TapGesture(count:2)
.onEnded({
rowTappedIndexValue = index
print("%%% Double Tap DisplayedStore: \(index)")
})) //.gesture
.simultaneousGesture(TapGesture()
.onEnded({
rowTappedIndexValue = index
print("*** Tap DisplayedStore: \(index)")
// self.isActiveOptionsSheetShowing.toggle()
model.removeFromDisplayStore (indexOfItemToRemove: rowTappedIndexValue)
})) //.gesture

Your wish has been granted!

Text("Tap Me!").gesture(      
    TapGesture(count: 2)
        .onEnded({ print("Tapped Twice!”)})
        .exclusively(before:
            TapGesture()
            .onEnded({print("Tapped Once!”) })          
    )              
)
