Steps to reproduce

I run flutter build macos on a project with native dependencies (Firebase) so that cocoapods needs to run. It used to work just fine, but now I'm getting the error message undefined method exists?' for File:Class. That method is called File.exists` in Ruby 3.2 … which is used by my version of cocoapods internally, so it seems. It might have started with Xcode 15.2 which I just installed, but I'm not sure.

I'm on Sonoma 14.2.1, using Homebrew 4.2.3, cocoapods 1.14.3 (which is dependent on Ruby 3.2.2 although this version isn't in the PATH) installed via brew install cocoapods, Xcode 15.2 and Flutter 3.18.0-19.0.pre.123

Expected results

It should run.

Actual results

[!] An error occurred while processing the post-install hook of the Podfile.

I checked on another with the same configuration but still with Xcode 15.1 and it doesn't work, so Xcode 15.2 is not the cause for the problem :(

I was about to file this. This also reproduces for me in a new project when adding integration_test (My best guess is this reproduces when introducing a platform dependent package) on the master/main branch and running on the macOS platform (doesn't reproduce for iOS simulator)

Steps to reproduce

  1. flutter create myapp
  2. cd myapp and then run the app from an IDE or terminal (flutter run -d macos)
  3. This should work fine.
  4. Add the integration_test package for instance
dev_dependencies:
  flutter_test:
    sdk: flutter
+ integration_test:
+   sdk: flutter
  1. Run the app again on macOS platform (flutter run -d macos)

I checked on another with the same configuration but still with Xcode 15.1 and it doesn't work, so Xcode 15.2 is not the cause for the problem :(

That's right. I had Xcode 15.1 yesterday when I first reproduced this issue. Today after upgrading Xcode 15.2 the issue persists.

FYI, currently, not only the current master is broken but also the latest beta.
