When I run pod init, I got the following error.

RuntimeError - [Xcodeproj] Unknown object version.

I've got very similar error: RuntimeError - [Xcodeproj] Unknown object version (56).

It turns out the cocopapods doesn't know how to work with Xcode 14 project version properly and it complains instead.

To solve the issue, open Xcode project on the right side utility panel and change the project version to Xcode 13.0 - compatible and you are good to go.

After investigation, I found I need to run

sudo gem update xcodeproj

Then run

pod init

this solution not work for me. – Maziar Saadatfar Sep 05 '22 at 21:36
Same. Updated `xcodeproj`, but still doesn't work. P.S. There is a temporary workaround - set `objectVersion` to 55 in `project.pbxproj`. Keep in mind, that it will be updated to 56 by Xcode if anything changes in the project. – Serzhas Sep 12 '22 at 12:51
update Xcode project and then pod install worked for me. Thanks!!! – Mike Critchley Sep 26 '22 at 07:38
Works for me after install cocoapods (1.11.3) and ffi (1.15.5) on MacOS 12.6 (M1). – Salvatore.isc Oct 23 '22 at 02:41

I initially tried this: sudo gem update xcodeproj

If it did not work (that was my case):

brew uninstall cocoapods

then

sudo gem install cocoapods

after that

pod init

This worked for me!

I got this error because podfile not created correctly.

I have created podfile as touch podfile instead of touch Podfile After researching log found that Podfile should start with capital.

Hope this helps!!
