You may use an alias in your .git/config

[alias]
        mydiff = !git diff | filterdiff -x "*/Project.xcodeproj/*"

You need filterdiff (from patchutils) for this trick.

sudo apt-get install patchutils

Still the diff isn't perfect, it leaves some garbage :

yannick@yannick-desktop:~/git-filter-test$ git mydiff
diff --git a/Project.xcodeproj/dummy.txt b/Project.xcodeproj/dummy.txt
index 3e1f9e6..89dfed9 100644
diff --git a/dummy2.txt b/dummy2.txt
index 91966ce..d9588a9 100644
