Proposal

Please re-state the problem that we are trying to solve in this issue.

iOS - Swipe gesture is possible when swiping for the first time

What is the root cause of that problem?

On iOS, react-native-tab-view's PanResponder not properly initialize with swipeEnabled: false on the first render, causing a issue where the first swipe gesture works before the setting takes effect.

What changes do you think we should make in order to solve the problem?

We should add key prop to the TopTab.Navigator component that includes both the navigator ID and the initial route name. This will ensure the navigator is properly mounted with the correct swipeEnabled configuration from the very first render.

key={`${id}-${validInitialTab ?? 'default'}`}

here

App/src/libs/Navigation/OnyxTabNavigator.tsx

Lines 166 to 170 in 24fac31

	<TopTab.Navigator
	/* eslint-disable-next-line react/jsx-props-no-spreading */
	{...rest}
	id={id}
	initialRouteName={validInitialTab}
