Summary:
When setting up Xcode, we also download the SDKs that is needed.
There might be cases where we can save money and time and skip the download

Summary:
Setting `ENV['RCT_USE_PREBUILT_RNCORE'] = '1'` when running nightlies on iOS will result in the following error:

The reason for this happening is that we precompile the iOS artifacts on CI using whatever version is set on main (by default version 1000). This works fine when using RCs and stable versions because before the publishing step we do a release commit (e.g 57ff54492f), which updates the react-native version.
This can be easily mitigated by invoking the `set-rn-artifacts-version` CLI right before building the iOS prebuilds.

[IOS] [FIXED] - Fix iOS version mismatch when using nightly prebuilds

This change reverts D78158734 which was a patch to make the dynamic frameworks work properly because we were not exporting the FBReactNativeSpec headers in prebuilds correctly.
This change fixes this, by exposritng those headers correctly.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52565
When we implemented caching in prebuilds for RN core for iOS, we were naïve in choosing the cache key. The current cache key does not consider the source code that is built and this can be problematic.
Imagine a contributor that changes a file in a React folder in their PR, but CI reuses a binary created from `main` and so everything will work well in CI even if the change contains an error.
This change globs over the header and implementation files in the React, ReactCommon and Libraries folder to ensure that we rebuild the code when iOS code changes.

Pull Request resolved: https://github.com/facebook/react-native/pull/52509
When building the CI Workflow to build React Native prebuilds, we were reading the react-native's version from the root package.json. This package.json is not updated by the release script, so the version is always 1000.
This makes the build process fail for stable releases.
With this change, we read the version from the right package.json file

Summary:
We found out that the XCFramework that is generated in CI is missing the headers.
This is happening because we run the setup script, the responsible to prepare the folder structure with the heaeders in the right place, only in the job that builds the slices. However, the headers are copied by the job that composes the XCFramework.
This change stores the header folder as an artifact in the build job and retrieves it in the compose job, so that the files are available to the XCFramework
