iOS: Add/update project files

[bisgardo]

The previous PR was not built on a Mac and therefore didn't include the updated iOS project files.

This change is the result of running flutter pub get on a Mac and ensures that the files are in sync.

Going forward, we'll need a CI workflow to check that the project files are in sync on all platforms (i.e. that flutter pub get doesn't change any files). This may be one that triggers only on changes to pubspec.yaml of the one that runs tests.

Could you create the epic for stage 3 with task CI/CD and mention in the task the step needs to be included.
