# Why clean up RCTBridgeModule.h?
Clean up one unnecessary import of RCTBridgeModule.h.
RCTBridgeModule includes a lot of header files, and this header is imported everywhere. The ultimate goal is that files (especially React Native infra files) should only import only what they need and not import the entirety of RCTBridgeModule.h whenever possible.
This way, certain headers that are Bridge-only can be compiled out of the new architecture with a flag.

Summary:
Changelog: [iOS][Internal] - Rework button/buttons handling on pointer events & add a new test checking for move events on chorded mouse button presses
This is a larger diff that largely stems from implementing a new pointer event platform test about chorded mouse button presses (adapted from https://github.com/web-platform-tests/wpt/blob/master/pointerevents/pointerevent_pointermove_on_chorded_mouse_button.html). In order to implement this test I added a new method, `step`, to an async test instance to allow you to run ad-hoc assertions labeled by the async test (like it's done in the original web platform test).
Once implementing the test I also discovered my current logic for handling the `button` and `buttons` properties was insufficient so I reworked it to handle more/most cases by making the `button` property instead determined by the change in the `buttons` property. This largely works but unfortunately due to what seems to be a bug in UIKit, chorded pointer "up" events receive the wrong button mask values so it's currently impossible to get this test fully passing on iOS. I've since submitted a bug report to Apple but my hopes aren't high that it will be focused on since it's such a niche issue.

Summary:
The motivation of this PR is for the Alert to follow the same style override (`overrideUserInterfaceStyle` being light/dark) as the one used by the root window (`UIApplication.sharedApplication.delegate.window`).
This is something that has worked previously because `RCTPResentedViewController()` was used to present the Alert (the behavior has changed in https://github.com/vonovak/react-native/commit/f319ff321c4b7c0929b99e3ebe7e1ce1fa50b34c). With the former approach, the alert would "inherit" the `userInterfaceStyle` of the view controller it was presented within (and that one, in turn, would "inherit" from `UIApplication.sharedApplication.delegate.window`).
With the current approach, the "style inheritance" does not work with the view controller being created [here](https://github.com/facebook/react-native/blob/f3db6cc52792e3006a16408df4ae40f3aee19a86/React/CoreModules/RCTAlertController.m#L24).
Because this viewcontroller instance does not have where to "inherit" the styling from, the styling might be different from the rest of the app. This PR fixes that.
## Changelog
[iOS] [Fixed] - fix: RCTAlertController's UserInterfaceStyle to follow root window
Pull Request resolved: https://github.com/facebook/react-native/pull/34218
Test Plan:
Instead of
```
self.overrideUserInterfaceStyle = UIApplication.sharedApplication.delegate.window.overrideUserInterfaceStyle;
```
you can do
```
self.overrideUserInterfaceStyle = UIUserInterfaceStyleDark;
```
and observe the result. So if the override is set, it'll manifest itself. If it's not set, the value of `UIApplication.sharedApplication.delegate.window.overrideUserInterfaceStyle` will be `UIUserInterfaceStyleUnspecified`, and it'll have no effect.

In addition this adds a check when an ActiveTouch is created to see if the pointer in question was hovering before the touch started or not, which is stored and leveraged once the touch is lifted to determine if we should treat the pointer as leaving the screen entirely or not.

Summary:
React Native is compiled downstream with MSVC, meaning the introduction of code depending on language extensions specific to gcc/clang may cause breakage.
We can enable `-Wpedantic` to flag any behavior not officially supported by the specified C++ standard. This will includes rules beyond what MSVC has trouble with, but seems to not have too many "noisy warnings".
This change enables -Wpedantic in BUCK targets within ReactCommon.
This makes the OSS C++ build for Android/iOS slightly more permissive than the internal build, A followup is to add the changes to OSS build logic as well, to avoid contributors seeing more errors upon internal submission. (checking with cortinico on how to do this for Android).
react-native-windows uses a higher warning level than `-Wall`, which is an additional cause of compilation failures, but is not addressed as part of this change.

Summary:
Changelog: [iOS][Internal] - Fix ghost pointer leave/out events firing due to view recycling on iOS
While implementing the properties on the PointerEvent object on iOS I noticed that in certain specific scenarios I was seeing pointerLeave events being fired seemingly without corresponding pointerEvent events and even more strangely, when the pointer wasn't even close to the view in question.
After a lot of research I discovered that this was caused by an incompatibility between my strategy of keeping track/identifying views which are being hovered and RN's handling of creating/deleting views on iOS. See on iOS RN has the `RCTComponentViewRegistry` class which manages the creation & deletion of UIViews and adds an optimization of recycling views instead of outright deleting them.
This is causing issues with my tracking of which views are hovered because I compare the view's object references which, while accurate towards confirming equality of an underlying UIView — isn't accurate in confirming the equality of views from react's perspective.
This diff addresses this issue by adding a simple wrapper class that can be used around the UIViews which stores the view's react ID at initialization time ensuring it doesn't get updated even if the underlying view's react id is. As an additional precaution the wrapper class will also not return the view it's wrapping if their react tags do not match.

Summary:
Changelog: [iOS][Internal] - Add isPrimary property implementation to the PointerEvent object
This diff adds the `isPrimary` property to the PointerEvent object iOS implementation. In addition this adds a related change where we "reserve" the 0 touch identifier for mouse events and the 1 identifier for apple pencil events. This is an easy way to ensure that these pointers are always consistent no matter what happens. Since mouse & pencil pointers should always be considered the primary pointer, that allows us to focus the more advanced primary pointer differentiation purely on touch events.
The logic for this touch event primary pointer differentiation is essentially setting the first touch it recieves as a primary pointer, setting it on touch registration, and sets all subsequent touchs (while the first touch is down) as not the primary pointers. When that primary pointer is lifted, the class property keeping track of the primary pointer is reset and then the **next** pointer (secondary pointers which had already started before the previous primary pointer was lifted are not "upgraded" to primary) is marked as primary. A new platform test is also included in this diff in order to verify the aforementioned behavior.

Summary:
Currently, with the Alert API on iOS, the only way to bold one of the buttons is by setting the style to "cancel". This has the side-effect of moving it to the left. The underlying UIKit API has a way of setting a "preferred" button, which does not have this negative side-effect, so this PR wires this up.
