[iOS] Fix release build error due to a casing issue in hermes tarball path after download prebuilt tarball

[wfern]

Summary:

In my mac, I use a case-sensitive volume and when I build a react-native 0.73 project it failed with an error that can't find the hermes release tarball to extract:

Node found at: /usr/local/bin/node
Preparing the final location
Extracting the tarball
tar: Error opening archive: Failed to open '/Volumes/Workspace/meet-art-link/ios/Pods/hermes-engine-artifacts/hermes-ios-0.73.1-Release.tar.gz'

Note the ...-Release.tar.gz in the error. In the disk it's ...-release.tar.gz.

The build fails in after download the release tarball in release mode because the hermes tarball name in the replace_hermes_version.js build script is capitalized, while the file is lowercase on disk.

The fix is to ensure the hermes tarball name's "build type" is lowercase just like the function that creates the tarballs in react-native release located in hermes_utils.js in getHermesPrebuiltArtifactsTarballName().

Perhaps it's better to retrieve the tarball name from the same method it's generated? E.g.:

const { getHermesPrebuiltArtifactsTarballName } = require('react-native/scripts/hermes/hermes-utils');

const tarballName = getHermesPrebuiltArtifactsTarballName(`${version}-${configuration}`);
const tarballURLPath = `${podsRoot}/hermes-engine-artifacts/${tarballName}`;

If yes, let me know to update the PR.

Changelog:

[iOS][Fixed] - Fix release build error due to a casing issue in hermes tarball path after download prebuilt tarball

Test Plan:

Use a case sensitive volume or system and build react-native 0.73 in release mode, it will fail. Apply the patch in this PR and it will work fine.

Thank you for opening this PR and fixing this issue.
I left a comment on lowercasing the version. I don't think it is required, because the versions usually have only numbers and dots. The only exception is for RCs, so it might make sense to keep the lowercase.

I don't think we have to lower case the version, or am I missing something?

[wfern]

In stable versions it is really not necessary but I added it for 2 reasons:

1. Because of the .RC versions as you said and I saw in the issue: iOS Release build from XCode fails at "[CP-User] [Hermes] Replace Hermes for the right configuration, if needed" step after adding a package #39903 some people having this same error and it could be because of this issue.
2. The method that generates the files in hermes_utils.js reduces the entire value including the version. So I think it really affects RC versions.
