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: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/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: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/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: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/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:
## Context
- If a NativeModule requires main queue setup, its `constantsToExport` method is executed on the main queue.
- In the TurboModule system, `constantsToExport` or `getConstants` is treated like a regular synchronous NativeModule method. Therefore, it's always executed on the JS thread.
This difference in behaviour is dangerous when we're A/B testing the TurboModule infra: One could write a NativeModule that requires main queue setup, and have it expose constants that access objects/state only accessible on the UI thread. This NativeModule would work fine in the legacy infra, which could be the case if the NativeModule author is testing locally. But once it ships to prod, it may run with the TurboModule system, and crash the application. To mitigate this risk, I'm removing this special main queue execution of `constantsToExport` from the legacy infrastructure.
## Consequences
- If a NativeModule's `constantsToExport` method accesses objects/state only accessible on the UI thread, it must do so by explicitly scheduling work on the main thread. I wrote up a codemod to fix this for our OSS modules: D21797048.
- Eagerly initialized NativeModules that required main queue setup had their constants calculated eagerly. After the changes in this diff, those NativeModules will have their constants calculated lazily. I don't think this is a big deal because only a handful of NativeModules are eagerly initialized, and eagerly initialized NativeModules are going away anyway.

This strategy swizzles UIApplication handleKeyUIEvent which is further upstream than our UIResponder. It also allows for single key hotkeys like pressing just `r` instead of `cmd+r`. It does this without interfering with typing input by checking the first responder first.
I've also updated our hotkey handling to support using just the keys like `r` in addition to `cmd+r`. In addition to brining these hotkeys more in line with other iOS tools, they're also easier to use and do not suffer the same issues hotkeys with modifiers like `cmd` have where keys are dropped.

Summary:
## Motivation
We got this crash T67304907, which shows a `EXC_BAD_ACCESS / KERN_INVALID_ADDRESS` when calling this line:
```
NativeModulePerfLogger::getInstance().asyncMethodCallBatchPreprocessStart();
```
There are no arguments in that call, so I figured the only error could be when we try to invoke `getInstance()` or `asyncMethodCallBatchPreprocessStart()`.
This diff:
1. Removes the `NativeModulePerfLogger::getInstance()` bit. Now NativeModulePerfLogger is used via regular static C functions. So, there's no way that simply invoking one of the logging functions crashes the application: there's no vtable lookup.
2. Inside each logging function, when perf-logging is disabled, the global perflogger should be `nullptr`. This diff makes it so that in that case, we won't execute any code in the control group of the perf-logging experiment.
## Changes
**How do we enable NativeModule perf-logging?**
- Previously:
- `NativeModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::setInstance(std::make_shared<FBReactNativeModulePerfLogger>(...))`.
- Now:
- `BridgeNativeModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
- `TurboModulePerfLogger::enableLogging(std::make_unique<FBReactNativeModulePerfLogger>(...))`
**How do we do NativeModule perf-logging now?**
- Previously:
- `NativeModulePerfLogger::getInstance().command(...args)`
- `TurboModulePerfLogger::getInstance().command(...args)`.
- Now:
- `BridgeNativeModulePerfLogger::command(...args)`
- `TurboModulePerfLogger::command(...args)`.
The benefit of this approach is that each method in `BridgeNativeModulePerfLogger` is guarded with an if check. Example:
```
void moduleCreateConstructStart(const char *moduleName, int32_t id) {
NativeModulePerfLogger *logger = g_perfLogger.get();
if (logger != nullptr) {
logger->moduleCreateConstructStart(moduleName, id);
}
}
```
Therefore, we don't actually execute any code when perf-logging is disabled.

## Investigation
We have 4 podspec targets that map to the same header namespace (i.e: `header_dir`) `ReactCommon`:
- **New:** `React-perflogger`: Directory is `ReactCommon/preflogger`, and contains `NativeModulePerfLogger.{h,cpp}`.
- `React-runtimeexecutor`: Directory is `ReactCommon/runtimeexecutor`, and contains only `RuntimeExecutor.h`
- `React-callinvoker`: Directory is `ReactCommon/callinvoker`, and contains only `CallInvoker.h`
- `ReactCommon/turbomodule/core`: Directory is `ReactCommon/turbomodule`, and contains C++ files, as well has header files.
**The problem:**
We couldn't import headers from `React-perflogger` in `ReactCommon/turbomodule/core` files.
**The cause:**
I'm not entirely sure why, but I was able to discern the following two rules by playing around with the podspecs:
1. If your podspec target has a cpp file, it'll generate a framework when `USE_FRAMEWORKS=1`.
2. Two different frameworks cannot map to the same `module_name` or `header_dir`. (Why? No clue. But something breaks silently when this is the case).
So, this is what happened when I landed `React-perflogger` (D21443610):
1. The TurboModules code generates the `ReactCommon` framework that uses the `ReactCommon` header namespace.
2. `React-runtimeexecutor` and `React-callinvoker` also used the `ReactCommon` header namespace. However, neither generate a framework because of Rule 1.
3. When I comitted `React-perflogger`, I introduced a second framework that competed with the `ReactCommon` framework (i.e: TurboModules code) for the `ReactCommon` header namespace. Rule 2 violation.
## Thoughts on renaming
- `<perflogger/NativeModulePerfLogger.h>` is too generic, and the `perflogger` namepsace is used internally within FB.
- `<react/perflogger/NativeModulePerfLogger.h>` matches our fabric header format, but I'm pretty sure that slashes aren't allowed in `header_dir`: I tested this and it didn't work. IIRC, only alphanumeric and underscore are valid characters for `header_dir` or `module_name`. So, I opted to just use `reactperflogger`.

Summary:
Per discussion in https://github.com/react-native-community/releases/issues/186 the iOS `PlatformColor()` function is documented to use the semantic color names provided by the system. The referenced HIG documentation itself links to the `UIColor` documentation for semantic colors names. However, these names differ depending on if you are viewing the new Swift API docs or the Objective C docs. The current Objective C implementation in react-native assumes Objective C UIColor selector names that are suffixed 'Color'. But in Swift, Apple provides a Swift Extension on UIColor that makes aliases without the the 'Color' suffix and then makes the original selectors invalid presumably via `NS_UNAVAILABLE_SWIFT`.
Since both selector names are valid depending on if you are using Objective C or Swift, let's make both forms be legal for `PlatformColor()`. In `RCTConvert.m` there is a dictionary of legal selector names. The code already supports the ability to have names be aliases of other selectors via a RCTSelector metadata key. The change adds code to the initialization of the map: it iterates over the keys in the map, which are all ObjC style UIColor selectors, and creates aliases by duplicating the entries, creating key names by stripping off the ObjC "Color" suffix, adds the RCTSelector key referring to the original and then appends these new Swift aliases to the map.

Currently, StatusBar native module manages the status bar on iOS globally, using `UIApplication.` APIs. This is bad because:
- those APIs have been deprecated for 4 years
- Apple really, really wants you to have an explicitly defined view controller, and control the status bar there
- it [breaks external native components](https://github.com/facebook/react-native/issues/25181#issuecomment-506792819)
- it's [not compatible with iPadOS 13 multi window support](https://github.com/facebook/react-native/issues/25181#issuecomment-506690818)
for those reasons I we should transition towards view controller-based status bar management.
With that, there is a need to introduce a default React Native root view controller, so I added `RCTRootViewController`. Using it is completely opt-in and there is no breaking change here. However I believe this should be a part of the template for new RN iOS apps.
Additionally, I added `RCTRootViewControllerProtocol` with hooks needed for RCTStatusBarManager to control the status bar. This means apps that want to have total control over their view controller can still opt in to react native VC-based status bar by conforming their root view controller to this protocol.
## Changelog
[iOS] [Added] - Added `RCTRootViewController` and `RCTRootViewControllerProtocol`
[iOS] [Fixed] - `UIViewControllerBasedStatusBarAppearance=YES` no longer triggers an error as long as you use `RCTRootViewController`
[iOS] [Fixed] - Status bar style is now correctly changed in multi-window iPadOS 13 apps if you use `RCTRootViewController` and set `UIViewControllerBasedStatusBarAppearance=YES`

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/28058
I'm taking the first step towards supporting iOS 13 UIScene APIs and modernizing React Native not to assume an app only has a single window. See discussion here: https://github.com/facebook/react-native/issues/25181#issuecomment-505612941
The approach I'm taking is to take advantage of `RootTagContext` and passing it to NativeModules so that they can identify correctly which window they refer to. Here I'm just laying groundwork.
- [x] `Alert` and `ActionSheetIOS` take an optional `rootTag` argument that will cause them to appear on the correct window
- [x] `StatusBar` methods also have `rootTag` argument added, but it's not fully hooked up on the native side — this turns out to require some more work, see: https://github.com/facebook/react-native/issues/25181#issuecomment-506690818
- [x] `setNetworkActivityIndicatorVisible` is deprecated in iOS 13
- [x] `RCTPerfMonitor`, `RCTProfile` no longer assume `UIApplicationDelegate` has a `window` property (no longer the best practice) — they now just render on the key window
Next steps: Add VC-based status bar management (if I get the OK on https://github.com/facebook/react-native/issues/25181#issuecomment-506690818 ), add multiple window demo to RNTester, deprecate Dimensions in favor of a layout context, consider adding hook-based APIs for native modules such as Alert that automatically know which rootTag to pass
## Changelog
[Internal] [Changed] - Modernize Modal to use RootTagContext
[iOS] [Changed] - `Alert`, `ActionSheetIOS`, `StatusBar` methods now take an optional `surface` argument (for future iPadOS 13 support)
[iOS] [Changed] - RCTPresentedViewController now takes a nullable `window` arg
[Internal] [Changed] - Do not assume `UIApplicationDelegate` has a `window` property
Pull Request resolved: https://github.com/facebook/react-native/pull/25425
Test Plan:
- Open RNTester and:
- go to Modal and check if it still works
- Alert → see if works
- ACtionSheetIOS → see if it works
- StatusBar → see if it works
- Share → see if it works

Summary:
This Pull Request implements the PlatformColor proposal discussed at https://github.com/react-native-community/discussions-and-proposals/issues/126. The changes include implementations for iOS and Android as well as a PlatformColorExample page in RNTester.
Every native platform has the concept of system defined colors. Instead of specifying a concrete color value the app developer can choose a system color that varies in appearance depending on a system theme settings such Light or Dark mode, accessibility settings such as a High Contrast mode, and even its context within the app such as the traits of a containing view or window.
The proposal is to add true platform color support to react-native by extending the Flow type `ColorValue` with platform specific color type information for each platform and to provide a convenience function, `PlatformColor()`, for instantiating platform specific ColorValue objects.
`PlatformColor(name [, name ...])` where `name` is a system color name on a given platform. If `name` does not resolve to a color for any reason, the next `name` in the argument list will be resolved and so on. If none of the names resolve, a RedBox error occurs. This allows a latest platform color to be used, but if running on an older platform it will fallback to a previous version.
The function returns a `ColorValue`.
On iOS the values of `name` is one of the iOS [UI Element](https://developer.apple.com/documentation/uikit/uicolor/ui_element_colors) or [Standard Color](https://developer.apple.com/documentation/uikit/uicolor/standard_colors) names such as `labelColor` or `systemFillColor`.
On Android the `name` values are the same [app resource](https://developer.android.com/guide/topics/resources/providing-resources) path strings that can be expressed in XML:
XML Resource:
`@ [<package_name>:]<resource_type>/<resource_name>`
Style reference from current theme:
`?[<package_name>:][<resource_type>/]<resource_name>`
For example:
- `?android:colorError`
- `?android:attr/colorError`
- `?attr/colorPrimary`
- `?colorPrimaryDark`
- `android:color/holo_purple`
- `color/catalyst_redbox_background`
On iOS another type of system dynamic color can be created using the `IOSDynamicColor({dark: <color>, light:<color>})` method. The arguments are a tuple containing custom colors for light and dark themes. Such dynamic colors are useful for branding colors or other app specific colors that still respond automatically to system setting changes.
Example: `<View style={{ backgroundColor: IOSDynamicColor({light: 'black', dark: 'white'}) }}/>`
Other platforms could create platform specific functions similar to `IOSDynamicColor` per the needs of those platforms. For example, macOS has a similar dynamic color type that could be implemented via a `MacDynamicColor`. On Windows custom brushes that tint or otherwise modify a system brush could be created using a platform specific method.
## Changelog
[General] [Added] - Added PlatformColor implementations for iOS and Android
Pull Request resolved: https://github.com/facebook/react-native/pull/27908
Test Plan:
The changes have been tested using the RNTester test app for iOS and Android. On iOS a set of XCTestCase's were added to the Unit Tests.

Summary:
As discussed in https://github.com/facebook/react-native/issues/27863, the following changes were made to modernize the internal default logging function:
- `RCTDefaultLogThreshold` is now set to `RCTLogLevelTrace` in both release and debug builds—the Apple logging system will discard uncollected log entires, while allowing for collection when needed
- `RCTLogLevel` is translated to the appropriate log type
- The log subsystem is "com.facebook.react.log"
- `RCTLogSource` translates to the appropriate category ("native"/"javascript")
- Log the provided message using `os_log_with_type`
Closes https://github.com/facebook/react-native/issues/27863
## Changelog
[iOS] [Changed] - Use Apple unified logging API (os_log)
Pull Request resolved: https://github.com/facebook/react-native/pull/27892
Test Plan:
## From Original PR
Ran a test app in the iOS simulator, and verified that logs are correctly displayed in Console.app as well as using the following command:
```sh
/usr/bin/xcrun simctl spawn booted log stream --level debug --style compact --predicate 'process=="ReactNativeTesterApp" && subsystem=="com.facebook.react.log"'
```
## Peter's Test Plan
1. Apply P125583473
2. Verify log output in Xcode P125583504
3. Apply this diff
4. Verify log output in Xcode P125583597
These appear unchanged, after digging into why, I realized that FB doesn't even use the default log function, we inject a custom one [here](https://fburl.com/diffusion/887a1axs). So this PR shouldn't affect us at all. :)

Summary:
Re-landing the reverted change:
This removes all callsites that rely on runtime checks to detect the target deployment version. We no longer need to check for iOS 10+ in a few places. Note: for this to compile, the hosting app needs to target iOS 10.0+.
