Testing release 0.74.1: multiple errors when creating a new project

[morukutsu]

Environment

react-native -v: 0.74.1
npm ls react-native-macos: 0.74.1
node -v: v22.6.0
npm -v: 10.8.2
yarn --version: 1.22.22
xcodebuild -version: Xcode 15.4 Build version 15F31d

Steps to reproduce the bug

Hello. I am testing the new release 0.74.1 with a clean project.

Test sequence:

# Install RN
npx react-native@latest init test_project --version 0.74.1
npx react-native-macos-init --version 0.74.1

The second command will fail with the same error as #2152.
Afaik, this one should have been fixed with a fix to react-native-macos-init.
Should be the package be updated on NPM as well? (see https://www.npmjs.com/package/react-native-macos-init?activeTab=versions)

# Previous command failed, to workaround:
yarn add "react-native-macos@0.74.1"

# And rerun to proceed
npx react-native-macos-init --version 0.74.1

Then it fails with another error:

Couldn't install Pods. Updating the Pods project and trying again...
Command `pod install` failed.
└─ Cause: Invalid `Podfile` file: uninitialized constant Pod::Podfile::FlipperConfiguration.

 #  from /Users/moru/Documents/Work/test_project/macos/Podfile:18
 #  -------------------------------------------
 #      # Flipper is not compatible w/ macOS
 >      :flipper_configuration => FlipperConfiguration.disabled,
 #      # An absolute path to your application root.
 #  -------------------------------------------

Commenting the line ":flipper_configuration => FlipperConfiguration.disabled" in the podfile will allow the build to proceed. However, on my end running npx react-native run-macos then does not open the app. It seems there's at least an issue with the podfile, but atm I don't have a good enough understanding of the system to debug it.

Thank you!

Indeed, :flipper_configuration was removed, so I think if that's still showing up in our template project, we need to remove it.

[morukutsu]

I had a look at https://github.com/microsoft/react-native-macos/blob/main/packages/rn-tester/Podfile to fix the Podfile, as it has been updated fairly recently.

However, even after removing :flipper_configuration and getting a successful build, when running npx react-native run-macos, nothing happens.

test_project % npx react-native run-macos

The app opens, there is a toolbar but no window. The previous version does work, with similar steps.

Thank you!

@morukutsu I think the problem is that bundleURL func is not defined in AppDelegate.mm.

Taken from https://react-native-community.github.io/upgrade-helper/?from=0.73.9&to=0.74.5#RnDiffApp-ios-RnDiffApp-AppDelegate.mm:

- (NSURL *)bundleURL
{
#if DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"];
#else
  return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif
}

Here's the error I got from Xcode.

An uncaught exception was raised
Subclasses must implement a valid getBundleURL method
