RefreshControl Patch - iOS 17.4 Haptic Regression
Patching RCTRefreshControl.mm temporarily to play an impact haptic on refresh when using iOS 17.4 or higher. Since
17.4, there has been a regression somewhere causing haptics to not play on iOS on refresh. Should monitor for an update
in the RN repo: https://github.com/facebook/react-native/issues/43388
RefreshControl Path - ScrollForwarder
Patching RCTRefreshControl.m and RCTRefreshControl.h to add a new forwarderBeginRefreshing method to the class.
This method is used by ExpoScrollForwarder to initiate a refresh of the underlying UIScrollView from inside that
module.
RCTPullToRefreshViewComponentView.mm Patch - RefreshControl initial props dropped on New Arch
TODO: Remove after bumping React Native to 0.82+ (fixed upstream by facebook/react-native#52615, #52584 and #53231).
On Fabric, updateProps diffs against _props, but the initial-layout replay in layoutSubviews passes
_props as the new props too, so the diff is a no-op and tintColor/progressViewOffset/title are never
applied on mount. This hides the pull-to-refresh spinner behind the floating home header (it stays at offset
0 instead of headerOffset). We diff against the oldProps argument instead, null-guarded with default
props for the create-mutation path.

RCTEnhancedScrollView.mm / RCTScrollViewComponentView.mm Patch - centerContent insets stale after content resize on New Arch
TODO: Remove after bumping React Native to 0.87+ (fixed upstream by facebook/react-native#56832, commit d50c1b5207; first shipped in 0.87.0-rc.0).
On Fabric, centerContent centers by computing contentInset in centerContentIfNeeded, but that
recompute only ran on setFrame/didAddSubview/scrollViewDidZoom - not when a state update assigns a
new contentSize in updateState. Any content that resizes after mount inside a centerContent
ScrollView (e.g. the lightbox image crop view getting its real aspect ratio from onLoad when the embed
has no aspectRatio metadata) keeps the old insets: content rests off-center and the excess inset creates
phantom scroll range, so the image can be dragged and parked off-center and the native scroll steals the
swipe-down-to-dismiss pan. The old architecture paired every contentSize update with re-centering in
RCTScrollView.updateContentSizeIfNeeded; Fabric dropped that link.
Backport of the upstream fix: setContentSize:/setCenterContent: overrides on RCTEnhancedScrollView
that call centerContentIfNeeded, plus the updateProps guards so the contentInset prop does not
fight the computed centering inset.
