ScrollEnabled={false} is not Respected on iOS

[pmaddaloni]

scrollEnabled={false} not respected on iOS (Fabric / New Architecture)

Environment

• Library version: 6.9.1
• React Native: 0.81.x
• Architecture: New Architecture (Fabric) enabled
• Platform: iOS
• Expo: 54

Description

When scrollEnabled is set to false on PagerView, horizontal swiping is still possible on iOS. The same setup works correctly on Android—swiping does nothing when scrollEnabled is false.

This occurs with the New Architecture (Fabric) enabled. The scrollEnabled prop appears to be applied in updateProps in RNCPagerViewComponentView.mm, but there may be a timing or initialization issue where:

1. The scroll view is created in willMoveToSuperview / initializeNativePageViewController
2. updateProps may run before the scroll view exists, or the initial scrollEnabled value is never applied at setup time
3. The scroll view defaults to scrollEnabled = YES and never receives the false value

Expected behavior

Setting scrollEnabled={false} should prevent horizontal page swiping, matching Android behavior.

Actual behavior

On iOS, the pager still responds to horizontal swipe gestures and changes pages even when scrollEnabled is false.

Workaround

Using react-native-gesture-handler with Gesture.Native() and a Gesture.Pan().blocksExternalGesture(native) to block swipes when scroll should be disabled. This is a reasonable workaround but requires extra dependencies and code.
