I recently upgraded the capacitor libraries from v5 to v6. It used to work find in v5 but after upgradation the command fails while running “ionic cap sync”. Below is the detailed error message

[capacitor] ✖ Updating iOS native dependencies with bundle exec pod install - failed!

Any help is highly appreciated

That’s a CocoaPods or ruby error, Capacitor 6 doesn’t have any changes related to CocoaPods or ruby.

Did you also do a computer OS update?

Between capacitor 5 to 6 upgrade, no OS update was made
