Reason to post an issue

I've read this issue and this issue. They don't provide any working solution and they are closed. I tried doing all the steps infinZero describes in his solution without any success. Also, I've read that the owner of the repository asks to share a sample project so that the team will be able to investigate. Since I've just created an empty project which demonstrates the issue - I decided to share it.

I have found a temporary solution (inspired by this pull request). I made the project's format Xcode 8.0-compatible and CocoaPods started to work as expected. Turning it back to Xcode 9.3-compatible breaks pod init again.

red - Xcode 9.3-compatible, green - Xcode 8.0-compatible

@iwheelbuy can you upgrade your xcodeproj gem to 1.5.6 and try again? I think this issue is already fixed.

@dnkoutso it helped!

I take it as it was fixed? :)

Going to close this one as it has already been fixed with xcodeproj 1.5.6.

Running bundle update will install the correct version of the xcodeproj gem dependency.

You can use: gem install cocoapods --pre --user
If you have "While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory" error

This might help someone as well,

I use RVM.
Had to change the ruby version from which RVM is pointing to the system one.
rvm use system
then I made gem list xcodeproj and I had two versions, (1.7.0 and 1.5.7). Removed the 1.5.7 and it started working.
