The working copy requires a newer version of Subversion than Xcode supports

Question

I just installed Xcode 4.6 (I had Xcode 4.5.1). I just opened an existing project and got this message:

The working copy "path/to/my project" requires a newer version of Subversion than Xcode supports.

I am currently using Cornerstone for svn, and understand that I can probably ignore this message - but since I want to be up-to-date, what do I need to do to resolve this issue?

Answer 1

The Xcode 4.6 default use the SVN 1.6.X, but you project's SVN info maybe 1.7.X (That may update by Cornerstone). As a result, when you try to update, the error message'll show. So we have to let the Xcode use the latest 1.7.X SVN.

I also met the same problem. That's my solution:

1. Install the Homebrew, we'll use it to install the latest SVN:

   ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

2. install the latest SVN:

   brew install subversion

3. Backup the old SVN file and link the latest SVN:

   cd /Applications/Xcode.app/Contents/Developer/usr/bin/        
   mkdir bak.svn
   mv svn* bak.svn
   ln -s /usr/local/Cellar/subversion/1.7.8/bin/svn* /Applications/Xcode.app/Contents/Developer/usr/bin/
   

4. Restart Xcode
