Brand new project fails to build React-hermes

[thompsonnoah]

Description

Hello! 👋

When creating a new React Native project on macOS, it fails to build due to some errors in the React-hermes pod. The errors are listed in the screenshot below.

Steps to reproduce

1. Create a new RN project with npx @react-native-community/cli@latest init AwesomeProject
2. Install Pods with pod install
3. Attempt to build with Xcode 16.3

React Native Version

0.79.2

Affected Platforms

Build - MacOS

Update: I was able to fix the build breaking. I did so by following the instructions here and getting a version of Hermes that builds. The version I downloaded for React Native 0.79 was the 2025-03-03 release.

I'm guessing what broke the build was the newer version of Hermes being downloaded from CocoaPods that isn't compatible with 0.79.

Going to leave this issue open for now (until I hear otherwise) as this may be an issue for others. And to notify the React Native team that this is a problem for new apps (also for any feedback on why this occurs).

[codingpotato]

I have the same issue now.

[davidcr90]

I think the same thing is happening to me, new project created with the CLI, on android it works, on ios it does not.

[kayakyakr]

I am also seeing this issue related to an Expo project. The combo of ReactNative (& Hermes), Expo, and expo-dev-menu that I found that allows this to work is:

React Native: 0.79.2
Expo: 53.0.9
expo-dev-client: 5.1.7

In my case, some change in 5.1.8 of expo-dev-client wasn't compatible with RN 0.79.2. Dunno if there's an action to take here.
