Xcode error message "The remote repository rejected commits" when pushing to Github

Question

I have a branch named develop that I pulled on, added some code, committed, pulled again, and am now trying to push but I get the following error message in Xcode:

The remote repository rejected commits.
Make sure you have permission to push to the remote repository and try again.

I switched to a different branch named feature and was able to pull and push on it fine.

I went to Xcode > Preferences > Accounts > Repositories then clicked on the repository I'm working on and verified my credentials and even re-entered them. But I still have the same problem (the feature branch works but the develop one throws up that message).

Why does the push work on one branch but not the other?

Answer 1

I got this error today and it wasn't until I tried to commit via another method did I actually find the reason. I had a file that was 230Mb and GitHub doesn't allow files that big (or at least for the account I have). So Xcode just wasn't being very helpful with its error message
