Summary:
i saw this a lot in the codebase, it's not optimal bc we're using two selectors when we only need one.
fastmod --extensions m,mm '\[\[(.*) alloc] init]' '[${1} new]' --dir xplat/js/react-native-github/*
i manually updated the callsites that this codemod couldn't handle (e.g., where there were more than one of these instances in a single line)

Summary:
This PR is to fix https://github.com/facebook/react-native/issues/29279, which image cannot show in iOS 14
As https://github.com/facebook/react-native/issues/29279#issuecomment-658244428 mention, this issue can be fixed by calling ` [super displayLayer:layer];` it it is still image, to let `UIImageView` handle still image rendering
## Changelog
[iOS] [Fixed] - Fix image cannot show in iOS 14
Pull Request resolved: https://github.com/facebook/react-native/pull/29420
Test Plan:
Image can be shown in iOS 14 build with Xcode 12 beta, using
```js
<Image source={require('./images/some_local_image.jpg')}/>
```
It may also need to test gif image is render correctly
```js
<Image source={{uri: 'https://some_remote_gif_image.gif'}}/>
```

Summary:
## Problem
When self is nil, this may crash in RCTUIImageViewAnimated.m.
```
_displayLink = [CADisplayLink displayLinkWithTarget:[RCTWeakProxy weakProxyWithTarget:self] selector:selector(displayDidRefresh:)];
```
## Fix
Replace `RCTWeakProxy` with a concrete class `RCTDisplayWeakRefreshable` that has the displayDidRefresh method, that calls the displayDidRefresh method in its weak target.

Summary:
In iOS 11, [CADisplayLink](https://developer.apple.com/documentation/quartzcore/cadisplaylink)'s frameInterval was deprecated in favor of preferredFramesPerSecond, but these two properties have different underlying assumptions.
- set frameInterval to 2 for 30fps
- set preferredFramesPerSecond to 30 for 30fps. When you use preferredFramesPerSecond, assume frameInterval is 1.
This fix ensures gifs in <Image> component will animate at same speed regardless of framerate.

The original commit removed the gating logic to enable the "fix" to T48583301. However, v236 was burned, and v237+ no longer had this gating, making it impossible to measure the impact of the fix.
This diff reverted the original gating removal until we confirm the fix in prod. Note: this is to be picked to RC v238 (but will have merge conflict for sure, will send a separate diff for the branch).

Summary:
@public
CADisplayLink strongly holds onto its target, so you have to use a weak proxy object to pass the target into the CADisplayLink.
Previously we passed a weak-self point (i.e. weakSelf) but this did not have the intended effect, since the pointer to self would still be passed to CADisplayLink, and thus it would hold onto the RCTUIImageViewAnimated strongly.
So is weakSelf doing anything other than using self?
It is but it's very minor and not useful. In the case that the object got de-allocated between assigning self to weakSelf and creating the CADisplayLink, then we would pass a nil target. This is actually impossible though because we are running an instance method, so self is implicitly retained! So semantically it is something different but in practice it is the same as passing self through.
Notes:
* This system was added originally in https://github.com/facebook/react-native/pull/24822
* https://github.com/facebook/react-native/pull/25636 then "enabled" this system by deprecating existing approach

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:
I discovered failing snapshot tests (T47222928, T47222859). They fail because `<Image>` doesn't work with base64 anymore.
There are two problems that are causing this.
1st is on iOS https://fburl.com/pw246vgw where if the image has 1 frame count, nothing is displayed.
2nd is in https://fburl.com/3im0u38r where if image is not within assets, we don't display it.

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

Summary:
The goal of this PR is to improve the pipeline currently used for displaying GIFs / animated images on iOS. It is achieved by not holding all of the decoded frames in memory at the same time, as well as happily releasing existing memory whenever possible. This code is a simplified version of what you would find in SDWebImage (it is nearly 1:1, with unsupported or uneeded things removed). By adopting this API, it also allows classes conforming to RCTImageURLLoader or RCTImageDataDecoder to return any decodable UIImages conforming to RCTAnimatedImage and have improvements to memory consumption. Because RCTAnimatedImage is just a subset of the SDAnimatedImage protocol, it also means that you can use SDWebImage easier with Image directly.
A nice to have would be progressive image loading, but is beyond scope for this PR. It would, however, touch most of these same parts.
