Same. I’m on latest CocoaPods version and have updated xcodeproj, as recommended in #11521, but it still doesn’t work.
P.S. Manually changing objectVersion to 55 in project.pbxproj does work, until I change anything in project, obviously.

«brew uninstall cocoapods» and reinstall cocoapods with «sudo gem install cocoapods»

Xcode : 14.0 (14A309)

This issue exists in new projects created using Xcode 14.0. Even pod init fails unless we downgrade the object version to 55 in project file.

«brew uninstall cocoapods» and reinstall cocoapods with «sudo gem install cocoapods»

This fixed it for me! Thanks 🙇‍♂️

reinstalling cocoapods did not fix the issue but downgrading project format did fix this issue.

Thank you so much, this fixed the issue for me.

gem update xcodeproj
sudo gem update xcodeproj
brew uninstall cocoapods
sudo gem install cocoapods

using these commands together solved my issue

Thank to thanhnam1042: «brew uninstall cocoapods» and reinstall cocoapods with «sudo gem install cocoapods»
This fixed for my project created by Xcode 14

After brew uninstall cocoapods I am getting a different error

LoadError - dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle, 0x0009): tried: '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e))) - /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle

This seems to be using the system gems shipped with macOS that is using x86 architecture

The pod command should use the gem compatible with ARM architecture.

«brew uninstall cocoapods» and reinstall cocoapods with «sudo gem install cocoapods»

Solved! 🥳 Thanks much!

1. sudo arch -x86_64 gem install ffi
2. arch -x86_64 pod install
   this two can solve your issue

gem update xcodeproj
sudo gem update xcodeproj
brew uninstall cocoapods
sudo gem install cocoapods

using these commands together solved my issue

I’m using Xcode 14.0, and this is working for me. Thanks @toufique-imam

Thank you, It works for me 👍

Below works for me (based on all the other answers) after I did brew install and pod init doesn’t work on Xcode 14 project I have.

sudo brew uninstall cocoapods
sudo gem install cocoapods
sudo gem update xcodeproj

Setting Project Format to Xcode 13.0-compatible also works, but I’d rather have it working with Xcode 14

«brew uninstall cocoapods» and reinstall cocoapods with «sudo gem install cocoapods»

This worked for me thanks!
