…#47520) Summary: Right now, when a 3p library needs to register a component in the component system, we have to crawl the library to try and get the mappng, best effort. With this approach, we are enriching the `codegenConfig` property to allow library developers to define the mapping themselves. For example: ```json //... "codegenConfig": { //.. "ios": { "component2ClassMapping": { "RNTMyNativeView": "RNTMyNativeViewComponentView" } } }, ``` means that the JS component `RNTMyNativeView` will be mapped to the `RNTMyNativeViewComponentView` class. This also work for local apps, and it warns the users about what libraries are using the deprecated approach, so they can open an issue or a PR to those libraries. ## Changelog: [iOS][Added] - Allow 3p developers to specify the association between components and classes in Fabric Reviewed By: dmytrorykun Differential Revision: D65666061

Summary: The `RCTThirdPartyLibraryComponentProvider` has been introduced to automate the component registration of third party libraries in the apps. However, it has some serious flaws: * It is generated in the React/Fabric folder, which means that it is generated in node_modules * It is generated when the user installs the components in the app, which means that we can't prebuild and redistribute React Native as a binary * it does not work with Frameworks and dynamic linking: in this scenarion, Fabric must build in isolation and if there are third party libraries involved, the lookup of the `xxxCls` function will fail This change removes the generation of the `RCTThirdPartyLibraryComponentProvider`. In the next diffs we will implement a different mechanism to register components ## Changelog [iOS][Changed] - Stop generating the RCTThirdPartyLibraryComponentProvider Reviewed By: dmytrorykun Differential Revision: D65601939
Summary:
This change reintroduce the generation of the `RCTThirdPartyComponentProvider` but in the right place and with the right patterns.
1. We are generating it in the user space, not in the node_modules (fixes the circular dependency)
2. We are not using weak function signature that have to be implicitly linked to some symbols found during compilation
The change needs to crawl the folder to retrieve the information it needs. We need to implement it this way not to be breaking with respect of the current implementation.
The assumption is that components have a function in their `.mm` file with this shape:
```objc
Class<RCTComponentViewProtocol> <componentName>Cls(void)
{
return <ComponentViewClass>.class;
}
```
I verified on GH that all the libraries out there follow this pattern.
A better approach will let library owner to specify the association of `componentName, componentClass` in the `codegenConfig`.
We will implement that as the next step and we will support both for some versions for backward compatibility.
