Summary:
The API was available only on Android (with no mention to that effect in the docs, AFAICT).
This commit adds a simple iOS implementation based on NSURLCache. It should be possible to
query the decoded image cache as well to provide higher fidelity (i.e. "disk", "memory",
"decoded") if the caller passes size, scale, etc. in addition to the image URL, but it's
probably not worth the complexity. The assumption is that callers are interested in the
durability rather than performance aspect of the returned information.
Tested with RNTester on iPhone emulator.

The `WKWebView` class doesn't expose a `scalesPageToFit` property, unlike `UIWebView`. Therefore, the `scalesPageToFit` RN prop is be a bit tricky to implement with `WKWebView`.
For the time being, this diff adds warnings to `<WebView/>` whenever `useWebKit={true}` and `scalesPageToFit` is set. I've also updated the documentation to reflect that we don't support `scalesPageToFit` prop with the new implementation of `<WebView/>`.

Summary:
When text is rendered in `WKWebView` WebKit component, the component itself can detect things like phone numbers, flight numbers, links, etc. and render them with additional functionality.
For example, when the text `apple.com` is detected, if the `link` data detector type is enabled, the web view will actually render a link that takes the user to the Apple home page.
In this diff, I implement the `dataDetectorTypes` prop. The data detector types supported are:
1. phoneNumber
1. link
1. address
1. calendarEvent
1. trackingNumber
1. flightNumber
1. lookupSuggestion
These enums are documented in the [[ https://developer.apple.com/documentation/webkit/wkdatadetectortypes | WKDataDetectorTypes docs ]].

`UIWebView` has been deprecated and replaced by `WKWebView`. This diff introduces a new component `WKWebView` that simply renders a `WKWebView` on iOS.
This is the first in the stack of many diffs that'll be required to fully replace `UIWebView` with `WKWebView` in the `<WebView/>` React Native component. Eventually, I hope to introduce a prop called `useWebKitImplementation`, which, when true, will force RN to use `WKWebView` instead of `UIWebView` for the `<WebView/>` component.
The only thing that's been implemented so far is the `source` property.

Summary:
This PR fixes an issue I have found while playing with native animated driver nodes.
I discovered the bug when using animated views that have both animated props and styles. See this snack to see an example: https://snack.expo.io/B17SFXy8Q
In that example we set `opacity` and `style` props which both contain animated props. This is not an usual way to do that, as normally you would place `opacity` inside the `styles` in which case the bug won't surface. But this is only done for demo purposes and in practice the problem will occur if you have a custom native view that exposes props that are not styles and can be animated.
In the above example you get this error:
> Invariant Violation: Attempt to get native tag from node not marked as "native"
When `opacity` is moved into `styles` container the problem no longer occurs.
The problem turned out to be related to the initialization code responsible for creating native animated nodes. In all subclasses of `AnimatedWithChildren` (like `AimatedAddition`) we only call `super.__makeNative` after we call `__makeNative` method on the child nodes. This order was reversed in `AnimatedStyle` and `AnimatedTransform`. As a result when `super.__makeNative` is called in `AnimatedStyle`, we try to call `__getNativeTag` on children nodes not yet marked as native which results in the error described above ("Attempt to get native tag...").
We should instead follow the order of calling `super.__makeNative` that is used in the remaining subclasses of `AnimatedWithChildren`. Such that all the children nodes are first converted to native prior to calling superclass method. This is what this PR is changing.

This diff fixes two bugs:
1. When you load a `<WebView/>` with an HTML source string, HTML source doesn't render in the `<WebView/>`. Instead, we get this warning: https://pxl.cl/grz3. Here's what the above page should look like when correctly rendered: https://pxl.cl/grzt
2. Furthermore, you render a blank `<WebView/>` (i.e: with no source prop), it should display a blank page. Instead, we get this warning: https://pxl.cl/grz3
**Bugfix:**
One solution I found was to ensure that `about:blank` is always whitelisted. That way, we don't ever abort navigations to blank pages, which occur when we do:
```ObjectiveC
/** Line 134 in RCTWebView.m */
[_webView loadHTMLString:@"" baseURL:nil];
```
and
```ObjectiveC
/** Line 115 in RCTWebView.m */
if (html) {

Summary:
On iOS, it is not possible to select a range of text using a `Text` component (see #13938). Because of how the `Text` component is implemented on iOS, this will not work without a complete re-write. On Android however, this is not an issue.
As the `TextInput` component has evolved, it can more or less be used as a drop-in replacement on iOS by setting `multiline={true}` and `editable={false}`. Except for one detail: the text input field has scrolling activated and it's not possible to turn off. (See #1391 and #15962).
This pull request addresses that issue, simply by exposing the `scrollEnabled` property:
```
<TextInput
multiline
editable={false}
scrollEnabled={false}
/>
```
1. Create a multiline `TextInput` component, with the attributes presented above.
2. Run on iOS
3. The `TextInput` field should not be able to scroll

- Introduce `trackColor` which encourages callers configuring the color to set colors for both cases.
- Introduce `ios_backgroundColor` which allows customizing the iOS-only background fill color.
- Deprecate `tintColor` because it is not obvious that this is for the `false` case.
- Deprecate `onTintColor` because the prop is named unconventionally like a callback.
- Renamed `thumbTintColor` to `thumbColor`.
This revision also cleans up the `Switch` component in the following ways:
- More precise Flow types for native components.
- Inline iOS-specific style (so that the code gets stripped on Android).
- Minor documentaiton cleanup.
After this commit, all deprecated props will continue working.
Next, I plan to introduce warnings.
Eventually (e.g. in a couple releases), we can drop support for the deprecated props.

Summary:
This PR increases the speed at which cached images are loaded and displayed on the screen. Images are currently cached in memory using RCTImageCache, but each time they are loaded, a round trip through RCTNetworking happens before RCTImageCache is even checked. This is likely so that RCTNetworking can handle the caching behavior required by the HTTP headers. However, this means that at the very least, images are read from disk each time they're loaded.
This PR makes RCTImageLoader check RCTImageCache _before_ sending a request to RCTNetworking. RCTImageCache stores a bit of information about the response headers so that it can respect Cache-Control fields without needing a roundtrip through RCTNetworking.
Here are a couple of graphs showing improved loading times before this change (blue) and after (red) with SDWebImage (yellow) as a baseline comparison. The increase is most evident when loading especially large (hi-res photo size) images, or loading multiple images at a time.
https://imgur.com/a/cnL47Z0
More performance gains can potentially be had by increasing the size limit of RCTImageCache: 1a6666a116/Libraries/Image/RCTImageCache.m (L39) but this comes at the tradeoff of being more likely to run into OOM crashes.

This should fix#18403.
When the user is inputting in Chinese/Japanese with <TextInput> in a controlled manner, the RCTBaseTextInputView will compare the JS-generated attributed string against the TextInputView attributed string and repeatedly overwrite the TextInputView one. This is because the native TextInputView will provide extra styling to show that some text is provisional.
My solution is to do a plain text string comparison at this point, like how we do for dictation.
Expected behavior when typing in a language that has "multistage" text input: For instance, in Chinese/Japanese it's common to type out the pronunciation for a word and then choose the appropriate word from above the keyboard. In this model, the "pronunciation" shows up in the text box first and then is replaced with the chosen word.
Using the word Japan which is written 日本 but first typed as にほん. It takes 4 key-presses to get to 日本, since に, ほ, ん, are all typed and then 日本 is selected. So here is what should happen:
1. enter に, onChange fires with 'に', markedTextRange covers 'に'
2. enter ほ, onChange fires with 'にほ', markedTextRange covers 'にほ'
3. enter ん, onChange fires with 'にほん', markedTextRange covers 'にほん'
4. user selects 日本 from the menu above the keyboard (provided by the keyboard/OS), onChange fires with '日本', markedTextRange is removed
previously we were overwriting the attributed text which would remove the markedTextRange, preventing the user from selecting 日本 from above the keyboard.
Cheekily, I've also fixed an issue with secure text entry as it's the same type of problem.

Summary:
Previously, I created two props, `accessibilityRole` and `accessibilityStates` for view. These props were intended to be a cross-platform solution to replace `accessibilityComponentType` on Android and `accessibilityTraits` on iOS.
In this stack, I ran a code mod to replace instances of the two old properties used in our codebase with the new ones.
For this diff, I did a search for all the remnant uses of `accessibilityComponentType` that was not caught by my script, and I manually changed them to `accessibilityRole` and `accessibilityStates`. If the same prop also set `accessibilityTraits` I also removed that here because the two new props works on both platforms.
It was difficult to write a script for this, because most of them were contextual changes.
Out of the contextual changes, most of them followed one of these two patterns:
Before:
```
const accessibilityComponentType = 'button';
const accessibilityTraits = ['button'];
if (this.props.checked) {
accessibilityTraits.push('selected');
}
if (this.props.disabled) {
accessibilityTraits.push('disabled');
}
contentView = (
<AdsManagerTouchableHighlight
accessibilityComponentType={accessibilityComponentType}
accessibilityTraits={accessibilityTraits}
```
After:
const accessibilityRole = 'button';
const accessibilityStates = [];
if (this.props.checked) {
accessibilityStates.push('selected');
}
if (this.props.disabled) {
accessibilityStates.push('disabled');
}
contentView = (
<AdsManagerTouchableHighlight
accessibilityRole={accessibilityRole}
accessibilityStates={accessibilityStates}
Before:
```
<PressableBackground
accessible={this.props.accessible}
accessibilityLabel={this.props.accessibilityLabel}
accessibilityTraits={this.props.accessibilityTraits}
```
After:
```
<PressableBackground
accessible={this.props.accessible}
accessibilityLabel={this.props.accessibilityLabel}
accessibilityRole={this.props.accessibilityRole}
accessibilityRole={this.props.accessibilityStates}
```
In addition to changing the props on the components,
Another fix I had to do was to add props accessibilityRole and accessibilityStates to components that don't directly inherit properties from view including text input and touchables.

Previously, I created two props, `accessibilityRole` and `accessibilityStates` for view. These props were intended to be a cross-platform solution to replace `accessibilityComponentType` on Android and `accessibilityTraits` on iOS.
In this stack, I ran a code mod to replace instances of the two old properties used in our codebase with the new ones.
For this diff, I wrote a script that focuses on replacing instances of the two properties that only added a single role to `accessibilityTraits` and `accessibilityComponentType`. In summary, this script:
* replaces instances of `accessibilityTraits = "<iOStrait>"` with `accessibilityRole = "<iOStrait>"`
* replaces instances of `accessibilityTraits = {['<iOStrait>']}` with `accessibilityRole = "<iOStrait>"`
* replaces instances of `accessibilityTraits = {"<iOStrait>"}` with `accessibilityRole = "<iOStrait>"`
* removes instances of `accessibilityComponentType`
```
The following is the codeshift script I wrote:

'use strict';
export default function transformer(file, api) {
const j = api.jscodeshift;
const root = j(file.source);
let hasChanges = false;
const elements = root.find(j.JSXElement);
let values;
let valuess;
let valuesss;
elements.forEach(path => {
const openEl = path.node.openingElement;
hasChanges = true;
for (let i = 0; i < openEl.attributes.length; i++) {
if (openEl.attributes[i].name.name === 'accessibilityComponentType') {
openEl.attributes.splice(i, 1);
}
if (openEl.attributes[i].name.name === 'accessibilityTraits') {
if (openEl.attributes[i].value.expression) {
if (openEl.attributes[i].value.expression.type === 'Literal') {
values = openEl.attributes[i].value.expression.value;
openEl.attributes[i] = j.jsxAttribute(
j.jsxIdentifier('accessibilityRole'),
j.literal(values),
);
}
}
if (openEl.attributes[i].value) {
if (
openEl.attributes[i].value &&
openEl.attributes[i].value.type === 'Literal'
) {
valuess = openEl.attributes[i].value.value;
openEl.attributes[i] = j.jsxAttribute(
j.jsxIdentifier('accessibilityRole'),
j.literal(valuess),
);
}
}
if (openEl.attributes[i].value.expression) {
if (
openEl.attributes[i].value.expression.type === 'ArrayExpression' &&
openEl.attributes[i].value.expression.elements.length === 1
) {
valuesss = openEl.attributes[i].value.expression.elements[0].value;
openEl.attributes[i] = j.jsxAttribute(
j.jsxIdentifier('accessibilityRole'),
j.literal(valuesss),
);
}
}
}
}
});
if (hasChanges) {
return root.toSource();
} else {
return null;
}
}
```
I then used this command to run the codemod:
```
./scripts/js1/node_modules/.bin/jscodeshift -c 10 --parser=flow --transform ./scripts/js1/commands/codeshift/add-accessibilityRoles/index.js /data/sandcastle/boxes/instance-ide/xplat/js/RKJSModules/Apps
hg status -n | xargs /data/sandcastle/boxes/instance-ide/tools/third-party/prettier/node_modules/.bin/prettier --single-quote --no-bracket-spacing --jsx-bracket-same-line --trailing-comma all --parser flow --write --require-pragma --no-config
hg status -n | xargs ./scripts/eslint/eslint --plugin lint --no-eslintrc --parser babel-eslint --rule "lint/sort-requires: 1" --fix
js1 build buckfiles
```
Lastly, I had to add a few manual fixes:
* Checked that instances of `accessibilityComponentType` that were deleted were indeed replaced with `accessibilityRole`
* Added props `accessibilityRole` and `accessibilityStates` to `TouchableWithoutFeedBack` components and `TextProps` because they don't inherit properties directly from view.

Summary:
This adds the accessibilityHint for View, Text and Touchable* on iOS.
The accessibilityHint provides some more information about an element
when the accessibilityLabel is not enough.
The accessibilityHint is a core accessibility property on iOS.
From https://developer.apple.com/documentation/objectivec/nsobject/1615093-accessibilityhint:
> An accessibility hint helps users understand what will happen when they perform an action on the accessibility element when that result is not obvious from the accessibility label.
Related issue: https://github.com/facebook/react-native/issues/14706
The npm scripts `test`, `flow`, `lint` and `prettier` are satisfied.
I added a couple of examples to the RNTester app. The Accessibility Inspector on Mac helps debugging accessibility stuff on a simulator, but it does not show the accessibilityHint. Therefore I tested the RNTester app on an iPhone 8 device using VoiceOver to verify the hint functionality. It works fine, and I've tested disabling and enabling "read hints" in the VoiceOver settings on the phone.
