[iOS] [Fixed] - Fix xcodebuild warnings in React-Core
Pull Request resolved: https://github.com/facebook/react-native/pull/29622
Test Plan:
- Nullability annotations should only affect compilation, but even though RNTester compiles, I'm not fully convinced that this won't break projects downstream. It would be good to get another opinion on this.
- The change in `RCTAllocateRootViewTag` is the only real logic change in this PR. We throw an exception if the root view tag is not in the correct format, so this change seems safe after some basic manual testing in RNTester.

Summary:
Right now, when two threads require two NativeModules, both threads fight for the same `std::mutex`. Why? Because NativeModule require can read from/write to the shared `std::unordered_map<std::string, TurboModuleHolder*>`.
**A Few Thoughts:**
- All threads should be able to read from the TurboModule cache concurrently, without issue. Only writes into the cache require exclusive access. *With our current setup, both reads and writes acquire exclusive access.*
- During the lifetime of an application, there will only be tens of NativeModule create events (i.e: writes into the TurboModule cache). However, there may be hundreds, if not thousands of TurboModule cache lookups. *We don't need to serialize those hundreds/thousands of TurboModule cache reads.*
This is a potential optimization opportunity for the TurboModule infra.
## Changes
This diff introduces a `std::shared_mutex` inside `RCTTurboModuleManager`. We use either the regular `std::mutex` or the `std::shared_mutex`, depending on whether `RCTTurboModuleSharedMutexInitEnabled()` is `YES`.

Fix a issue that RCTModalHostView can't be dismissed while being presented
Steps To Reproduce
A native modal presented view controller is being dismissed before the first screen shows.
A RCTModalHostView is presented when the first screen shows.
The RCTModalHostView will be dismissed after an asynchronous callback.
If the callback was called before the completion of the presenting animation, the RCTModalHostView will not be dismissed.

Summary:
Microsoft’s RN for macOS fork supports the Hermes engine nowadays https://github.com/microsoft/react-native-macos/pull/473. As a longer term work item, we’ve started moving bits that are not invasive for iOS but _are_ a maintenance burden on us—mostly when merging—upstream. Seeing as this one is a recent addition, it seemed like a good candidate to start with.
As to the actual changes, these include:
* Sharing Android’s Hermes executor with the objc side of the codebase.
* Adding a CocoaPods subspec to build the Hermes inspector source and its dependencies (`Folly/Futures`, `libevent`).
* Adding the bits to the Xcode build phase script that creates the JS bundle for release builds to compile Hermes bytecode and source-maps…
* …coincidentally it turns out that the Xcode build phase script did _not_ by default output source-maps for iOS, which is now fixed too.
All of the Hermes bits are automatically enabled, on macOS, when providing the `hermes-engine-darwin` [npm package](https://www.npmjs.com/package/hermes-engine-darwin) and enabling the Hermes pods.
## Changelog
[General] [Added] - Upstream RN macOS Hermes integration bits
Pull Request resolved: https://github.com/facebook/react-native/pull/29748
Test Plan:
Building RNTester for iOS and Android still works as before.
To test the actual changes themselves, you’ll have to use the macOS target in RNTester in the macOS fork, or create a new application from `master`:

# Problem
The problem was setting `_backedTextInputView.attributedText` to nil inside `[RCTTextInputComponentView prepareForRecycle]`.
Ordinarily this isn't a problem becase `UIManager::updateState` drops the update if the ShadowNode no longer exists. But in certain cases the ShadowNode can exist, empty string being set as its value
# Fix
Fix is trivial, invalidate state before nullifying `_backedTextInputView`. This prevents the state update from being dispatched.
# Discussion
We should go over all other components and make sure state is invalidated as first thing in `[RCTViewComponentView prepareForRecycle]`.

When double tapping to expand/truncate the text, the rect of the element always moves to the top and then come back to the original place.. This seems because after truncating/expanding the text, the view would re-render and the container would be destroyed. I used the API accessibilityFrameInContainerSpace to set the frame before. And the frame was not updated properly. Converting the bound to the screen coordinates and set accessibilityFrame directly fixed it.

To get `RCTEventDispatcher` working bridgeless, I need to support 2 new bridge methods:

- `- (void)dispatchBlock:(dispatch_block_t)block queue:(dispatch_queue_t)queue;`
For (1) I copied the bridge impl exactly. For (2), the bridge only dispatches to JS thread, else uses `dispatch_async`. I only added support for dispatching to JS thread, callers can `dispatch_async` themselves if they want to.

Summary:
This should fix https://github.com/facebook/react-native/issues/29082 and https://github.com/facebook/react-native/issues/10471
Currently when an alert is being shown while a modal is being dismissed, it causes the alert not to show and In some cases it causes the UI to become unresponsive. I think this was caused by using RCTPresentedViewController to try and display the Alert the currently presented view. The View the Alert was going to be shown on is dismissed and the modal doesn't show. I implemented a new RCTAlertController to show the alert on top of the view, the modal being dismissed should now not interfere with the alert being shown.
## Changelog
[iOS] [Fixed] - Fixed showing Alert while closing a Modal
Pull Request resolved: https://github.com/facebook/react-native/pull/29295
Test Plan:
To recreate the bug:
1. npx react-native init Test --version 0.63.0-rc.1
2. Paste the following code into App.js
```javascript
/**
* Sample React Native App
* https://github.com/facebook/react-native
*
* format
* flow strict-local
*/
import React from 'react';
import {
SafeAreaView,
StyleSheet,
View,
Text,
StatusBar,
Modal,
Alert
} from 'react-native';
const App: () => React$Node = () => {
const [visible, setVisible] = React.useState(false)
const onShowModal = () => {
setVisible(true)
}
onCloseBroken = () => {
setVisible(false)
Alert.alert('Alert', 'Alert won\'t show')
}
onCloseWorking = () => {
setVisible(false)
setTimeout(() => Alert.alert('Alert', 'Works fine'), 10)
}
return (
<>
<StatusBar barStyle="dark-content" />
<SafeAreaView style={styles.container}>
<Text onPress={onShowModal}>Show modal</Text>
</SafeAreaView>
<Modal animationType="fade" visible={visible} onRequestClose={onCloseWorking} >
<View style={styles.container}>
<Text onPress={onCloseBroken}>Close modal immediately</Text>
<Text onPress={onCloseWorking}>Close modal with delay</Text>
</View>
</Modal>
</>
)
}
const styles = StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
justifyContent: 'space-around',
},
})
export default App
```
3. cd Test && npx react-native run-ios
4. Show the modal and click the `Close modal immediately` button
The first button doesn't show the alert, the second does because it gets rendered after the modal view is dismissed. After this commit, the alert always shows on top of every view properly. You can test by pointing the react native package to my branch by modifying the package json file like this
```
"react-native": "https://github.com/devon94/react-native.git#fix-ios-modal"
```
I was unable to reproduce the case where it causes the UI to be responsive in the test app but was able to reproduce it in our react native app at work. I can provide a video later if needed but the code is too complex to simplify into a test case.

No part of Yoga, RN, Litho or CK uses this value yet. `relative` and `static` values behave the same way for now. We also do not change any defaults. So, it should be fine.

[Internal] - Add an condition to exclude accessibilityRole that not currently used
Since I've added all the possible values in accessibilityRole enum, it is necessary to gate what needs to be an accessibilityElement. SO I add a condition to exclude accessibilityRole that not currently used.

Summary:
Here we use `TelemetryController` to instrument mounting transactions in RCTMoutingManagers and wire that with RCTMountingTransactionObserving protocol. Now, performance trackers (flags) that we use can obtain this information and report to some server-side infrastructure. (Which will be implemented in future diffs.)

[Internal] - Reword the guide words to make it more generic.
Considering the case that some languages are RTL so swiping right cannot guarantee to move to the link. iOS can handle the order of the words and accessibilityElements according to the language. But the accessibilityHint we hardcoded would be an issue. So we decided to reword it to be more generic.

Summary:
TurboModule eager initialization is a bit dangerous if we get it wrong, which we did (twice): T69449176.
This diff gates TurboModule eager init behind a MC, so that we can control (i.e: turn off/on, and do gradually rollout of) TurobModule eager initialization in isolation from the larger TurboModules experiment.

Summary:
## Why?
1. RCTTurboModuleLookupDelegate sounds a bit nebulous.
2. In JS and Java, we use a `TurboModuleRegistry` interface to require TurboModules. So, this diff will make JS, Java, and ObjC consistent.

Summary:
## Context
1. In FBReactModule jsExecutorForBridge, we asynchronously initialize a list of TurboModules on the main queue: https://fburl.com/diffusion/i56wi3px
2. After initializing the bridge, we start executing the JS bundle, here: e23e9328aa/React/CxxBridge/RCTCxxBridge.mm (L414-L417). Since bridge initialization knows nothing about TurboModule eager initialization, this happens concurrently with 1, and starts requiring NativeModules/TurboModules on the JS thread.
## The Race
1. Both the main thread and the JS thread race to create a TurboModule that requires main queue setup.
2. The JS thread wins, and starts creating the TurboModule. Meanwhile, the main thread blocks, waiting on a signal here, in RCTTurboModuleManager: e23e9328aa/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm (L430)
3. The JS thread tries to dispatch_sync to the main queue to setup the TurboModule because the TurboModule requires main queue setup, here: e23e9328aa/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm (L402)
4. We deadlock.
## The fix
Succinctly, NativeModule eager initialization finishes before execute the JS bundle, but TurboModule initialization doesn't. This diff corrects that mistake.
The changes in this diff:
1. The RN application via the TurboModuleManager delegate can now optionally provide the names of all eagerly initialized TurboModules by implementing two methods `getEagerInitModuleNames`, `getEagerInitMainQueueModuleNames`.
2. The TurboModuleManager grabs these two lists from the delegate, and exposes them to its owner via the `RCTTurboModuleRegistry` protocol.
3. The RCTCxxBridge, which already owns a `id<RCTTurboModuleRegistry>` object, uses it to eagerly initialize the TurboModules in these two lists with the correct timing requirements.
This is exactly how we implement eager initialization in Android.
**Note:** Right now, phase one and two of TurboModule eager initialization happen after phase one and two of NativeModule eager initialization. We could make the timing even more correct by initializing the TurboModules at the exact same time we initialize the NativeModules. However, that would require a bit more surgery on the bridge, and the bridge delegate. I think this is good enough for now.

Summary:
`RCTModuleData gatherConstants` is [used by `RCTModuleData exportedConstants` to compute and return the constants exported to JS](https://fburl.com/diffusion/ssg4jbeu). However, `RCTModuleData gatherConstants` is also [used by `RCTCxxBridge` to pre-compute NativeModule constants during bridge startup](https://fburl.com/diffusion/nfmjc1ke). Therefore, since `RCTModuleData gatherConstants` can be used outside the context of a JS require, we cannot start the JSRequireEnding marker inside `RCTModuleData gatherConstants` directly.
This diff moves the body of `RCTModuleData gatherConstants` into `gatherConstantsAndSignalJSRequireEnding:(BOOL)startMarkers`:
- `RCTModuleData gatherConstants` calls `RCTModuleData gatherConstantsAndSignalJSRequireEnding:NO`
- `RCTModuleData exportedConstants` calls `RCTModuleData gatherConstantsAndSignalJSRequireEnding:YES`. **Note:** This is okay, because `RCTModuleData exportedConstants` is only called inside `RCTNativeModule::getConstants()`.
This should make sure that we don't start the JSRequireEnding marker outside of a JS require.

Summary:
This diff inlines all mount-instruction functions into a single one - RCTPerformMountInstructions.
The main purpose is to reduce the number of calls to `RCTComponentViewRegistry` for some instructions. E.g., before the change, the `Insert` (or `Update`) instruction had seven identical calls to the registry. That's not a huge deal but there is no need to pay for it either. Maybe it can save us a couple of milliseconds during TTI.
The code of those functions is quite straight-forward, so this change probably even improves readability.

Summary:
Pet Peeve: Metro is a brand name. You don't say "the Metro server" just like you don't say "the iPhone phone". This is a leftover from when it used to be called "the packager server".
Note: It makes sense to refer to "the Metro server" when talking about it in the context of Metro's features, like if you are discussing "Metro's bundling" and "Metro's server". However, when talking about the tool itself, just Metro is enough.

Summary:
This is the first implementation stage of on-demand child views mounting for <ScrollView> feature.
It works this way. When mounting layer requests mounting of a subview of <ScrollView>, the component does not mount it immediately. Instead, it stores it in an internal collection, and then after the transaction finishes use that to mount views that are in a visible area.
Then we re-evaluate which child views are should be mounted and unmounted on every significant onScroll event. We use some leeway to do it not so often to save CPU cycles on scrolling.
This feature already works fine but to make it shippable we need to integrate it with an `overflow inset` feature to make it 100% reliable in complex cases when some views have overflow content.
