Looks like your Ruby 3.4.1 is using gems 3.4.0 which is causing a ruby error in Cocoapods

[brunoinds]

🎉 I've solved this problem with this 3 steps:

1. Re-install cocoapods

sudo gem uninstall cocoapods
sudo gem install cocoapods

2. Update Podfile:

cd ios/App
rm -rf Pods Podfile.lock
pod repo update
pod install

3. Cap Sync:

ionic cap sync ios
ionic cap build ios
