J'essaie de changer de branche dans git mais j'obtiens ce message d'erreur :
error: you need to resolve your current index first
J'utilise git sous 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")
