Summary:
In https://github.com/facebook/react-native/issues/25427, radex added initial support for running React Native projects on macOS via Catalyst. However, `RCTWebSocket` was disabled for that target because of some compilation issues. This meant that running projects via a connection to the packager wasn't possible: no live reload, and projects must be run in "Release" mode. It also meant making manual changes to Xcode projects deploying to macOS and scattering a number of conditional checks throughout the codebase.
In this change, I've implemented support for `RCTWebSocket` on the macOS target and re-enabled the affected features. Live reload and the inspector now work for macOS targets. Manual modifications of Xcode build settings are no longer necessary for react-native projects running on macOS.
### Limitations
There's no binding which displays the developer menu (since there's no shake event on macOS). We'll probably want to add one, perhaps to the menu bar.
I've chosen not to commit the modifications to RNTester which enable macOS support, since that would imply more "official" support for this target than I suspect you all would like to convey. I'm happy to add those chunks if it would be helpful.
## Changelog
[iOS] [Added] - Added web socket support for macOS (Catalyst), enabling debug builds and live reload
Pull Request resolved: https://github.com/facebook/react-native/pull/27469
Test Plan:
* Open RNTester/RNTester.xcodeproj with Xcode 11.2.1, run it like a normal iOS app -- make sure it compiles and runs correctly (no regression)
* Select "My Mac" as device target, and run. You may need to configure a valid development team to make signing work.
* RNTester should run fine with no additional configuration. Modify a file in RNTester, note that live reload is now working.
* Test the developer inspector. To display the developer menu, you'll need to manually show it; here's an example diff which does that:
```

Summary:
This diff allows re-connecting to the debugger websocket after reloading so that if, for example, metro has restarted, we'll reconnect to allow for debugging. Previously you would need to kill the app and re-open it to re-register the debugger websocket.

Summary:
blairv recently brought an issue with heap snapshots to our attention: When
captured from iOS, the viewer would quite regularly hang forever instead of
capturing the snapshot.
Further investigation showed that it was because the message that Hermes sends
to indicate that it had finished sending chunks of the heap snapshot was
arriving to chrome before the last chunk of the snapshot. This caused Chrome
to believe the snapshot was malformed.
I confirmed that:
- Sends from the Hermes Inspector were occurring in the correct order.
- The WebSocket protocol, being built on top of TCP, also preserves order.
- The Inspector Proxy in Metro was preserving the order of requests it was
given, but the responses were already in the wrong order when they reached
it.
This left the code that Hermes' Inspector calls into to send its messages. On
iOS, the logic to send the request is run on the global dispatch queue which
can and does schedule jobs concurrently with each other. Because the messages
containing heap snapshot chunks are much larger than the "Ok" message used to
indicate the end of the snapshot, the earlier chunk message would often lose
the race with the later "Ok" message.
There was already a serial background queue used by the websocket server to
schedule the actual sending of the message. I re-use it in this diff to
process the message as well.
The architecture of the [same code in Android](https://our.intern.facebook.com/intern/diffusion/FBS/browse/master/xplat/js/react-native-github/ReactAndroid/src/main/java/com/facebook/react/devsupport/InspectorPackagerConnection.java?commit=64c8954ec7be555509437db6944b9a71a350e87c&lines=283) initially seems to be broken in
the same way, but it is not, because AsyncTask does not run tasks concurrently
any more because Google found it exposed too many concurrency bugs to do so.
pakoito, it seems like you might be somewhat familiar with what's going on
here. Let me know if what I've done is sensible.

Summary:
This is my proposal for fixing `use_frameworks!` compatibility without breaking all `<React/*>` imports I outlined in https://github.com/facebook/react-native/pull/25393#issuecomment-508457700. If accepted, it will fix https://github.com/facebook/react-native/issues/25349.
It builds on the changes I made in https://github.com/facebook/react-native/pull/25496 by ensuring each podspec has a unique value for `header_dir` so that framework imports do not conflict. Every podspec which should be included in the `<React/*>` namespace now includes it's headers from `React-Core.podspec`.
The following pods can still be imported with `<React/*>` and so should not have breaking changes: `React-ART`,`React-DevSupport`, `React-CoreModules`, `React-RCTActionSheet`, `React-RCTAnimation`, `React-RCTBlob`, `React-RCTImage`, `React-RCTLinking`, `React-RCTNetwork`, `React-RCTPushNotification`, `React-RCTSettings`, `React-RCTText`, `React-RCTSettings`, `React-RCTVibration`, `React-RCTWebSocket` .
There are still a few breaking changes which I hope will be acceptable:
- `React-Core.podspec` has been moved to the root of the project. Any `Podfile` that references it will need to update the path.
- ~~`React-turbomodule-core`'s headers now live under `<turbomodule/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-turbomodulesamples`'s headers now live under `<turbomodulesamples/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-TypeSaferty`'s headers now live under `<TypeSafety/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511040967.
- ~~`React-jscallinvoker`'s headers now live under `<jscallinvoker/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- Each podspec now uses `s.static_framework = true`. This means that a minimum of CocoaPods 1.5 ([released in April 2018](http://blog.cocoapods.org/CocoaPods-1.5.0/)) is now required. This is needed so that the ` __has_include` conditions can still work when frameworks are enabled.
Still to do:
- ~~Including `React-turbomodule-core` with `use_frameworks!` enabled causes the C++ import failures we saw in https://github.com/facebook/react-native/issues/25349. I'm sure it will be possible to fix this but I need to dig deeper (perhaps a custom modulemap would be needed).~~ Addressed by 33573511f0.
- I haven't got Fabric working yet. I wonder if it would be acceptable to move Fabric out of the `<React/*>` namespace since it is new? �
## Changelog
[iOS] [Fixed] - Fixed compatibility with CocoaPods frameworks.
Pull Request resolved: https://github.com/facebook/react-native/pull/25619
Test Plan:
### FB
```
buck build catalyst
```
### Sample Project
Everything should work exactly as before, where `use_frameworks!` is not in `Podfile`s. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which has `use_frameworks!` in its `Podfile` to demonstrate this is fixed.
You can see that it works with these steps:
1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout fix-frameworks-subspecs`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`
The sample app will build and run successfully. To see that it still works without frameworks, remove `use_frameworks!` from the `Podfile` and do steps 3 and 4 again.
### RNTesterPods
`RNTesterPodsPods` can now work with or without `use_frameworks!`.
1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.
4. Run the tests again and see that it still works with frameworks enabled.

Summary:
This PR adds initial support for Project Catalyst a.k.a. UIKitForMac. This is not yet meant for production, but this is enough for RNTester to successfully compile and mostly work :)
Some APIs are not supported on the Mac -- e.g. telephony, and deprecated APIs are removed on Mac ���-- those had to be ifdef'd out via platform checks.
The biggest limitation right now is that I couldn't get Web Socket code to successfully compile, and so there are a lot of temporary platform checks for that , and the RCTWebSocket.xcodeproj is marked as not supporting UIKitForMac. Again -- temporary, until someone with more knowledge knows how to fix this.

## Changelog
[iOS] [Added] - Fixed compilation for macOS (Project Catalyst) -- not meant for production use yet
Pull Request resolved: https://github.com/facebook/react-native/pull/25427
Test Plan:
- Open RNTester/RNTester.xcodeproj with Xcode 10.2, run it like a normal iOS app -- make sure it compiles and runs correctly (no regression)
- Open the same project with Xcode 11 beta 2 (or higher) on macOS Catalina beta, select "My Mac" as device target, and run -- see that it actually compiles and runs. **Note** there are unfortunately some required steps:
- change build configuration to Release (because packager doesn't work correctly yet)
- change development team to yours if Xcode tells you to
- go to RNTester project → Build phases → Link binary with libraries, and change `platforms` for `libRCTWebSocket.a` to `iOS` (without Mac compatibility). I can't commit that change because it breaks compatibility with earlier Xcode versions
The two extra steps for successful compile will disappear once web socket compilation for Catalyst is fixed
