A better sample gitignore file for XCode Cocoa projects on Mac OS X (iPhone, too)

When we switched to git last year (from Subversion) we took a little time and beefed up our ignore file. While working on another project recently, I realized that most of the example .gitignore files for Cocoa/MacOSX/XCode on the web are really not terribly complete, and the results can be very frustrating when you're just getting started with a new repository.

Here's a better .gitignore example. Let me know if I left anything out. (I saw a few examples from people who exclude the pattern "profile", but as far as I can tell, that's really not a very good idea. I assume they have a specific use case of some kind which eludes my pondering.)

The current version of this file can be found on GitHub:
.gitignore for Xcode, Cocoa, Swift, Objective C, Mac OS X, iOS, TV, Watch

A better .gitignore for XCode, Cocoa, and Mac OS X git repositories:

# Mac OS X Finder and whatnot
.DS_Store

# Sparkle distribution Private Key (Don't check me in!)
dsa_priv.pem

# XCode (and ancestors) per-user config (very noisy, and not relevant)
*.mode1
*.mode1v3
*.mode2v3
*.perspective
*.perspectivev3
*.pbxuser

# Generated files
VersionX-revision.h

# build products
build/
*.[oa]


# Other source repository archive directories (protects when importing)
.hg
.svn
CVS

# automatic backup files
*~.nib
*.swp
*~
*(Autosaved).rtfd/
Backup[ ]of[ ]*.pages/
Backup[ ]of[ ]*.key/
