[!] Xcode - develop for iOS and macOS
✗ CocoaPods installed but not working.
You appear to have CocoaPods installed but it is not working.
This can happen if the version of Ruby that CocoaPods was installed with
is different from the one being used to invoke it.
This can usually be fixed by re-installing CocoaPods.
To re-install see
https://guides.cocoapods.org/using/getting-started.html#installation for
instructions.
