Xcode Local SVN

Question

As I get into more serious project development in Xcode I decided to setup a local SVN repo. It seemed surprisingly easy and now I'm checking in and out files within XCode.

Two quick questions.

After adding a few files and commit some other changes, a 'M' has appeared at the top level of the Xcode "Groups & Files" column. I assume 'M' stands for merge (as I've noticed it appears when I modify files) but why does it now appear next to the top level project icon with no changes and visible options?

Also newbie question but I checked a base version of my 7MB Xcode project and then copied it into a branch. Yet my SVN directory is still under 3MB. Is this just SVN goodness or am I missing something? Is it safe to assume that if I backup and save the SVN directory I have saved my world?

Answer 1

I found XCode's interaction with the SVN to be a little weak, so I now use Cornerstone to handle the SVN.

Separation of concerns, and all that :)

Note: CW because this doesn't actually answer the question, but it was too long for a comment.

Answer 2

'M' stands for 'Modified'. If the project file appears to be modified (but nothing underneath it), it may be that XCode is updating the project file to a newer format.
