git - Why can I not switch branches?

Question

I'm trying to switch branches in git but I'm getting this error message:

error: you need to resolve your current index first

I'm using git under xcode4

git status
# On branch DateCode
# Unmerged paths:
#   (use "git reset HEAD <file>..." to unstage)
#   (use "git add/rm <file>..." as appropriate to mark resolution)
#
#   both modified:      Whereami.xcodeproj/project.xcworkspace/xcuserdatauser.xcuserdatad/UserInterfaceState.xcuserstate
#
no changes added to commit (use "git add" and/or "git commit -a")

Try this if you don't want any of the merges listed in git status:

git reset --merge

This resets the index and updates the files in the working tree that are different between <commit> and HEAD, but keeps those which are different between the index and working tree (i.e. which have changes which have not been added).

If a file that is different between <commit> and the index has unstaged changes -- reset is aborted.
