Git ignore file for Xcode projects

Which files should I include in .gitignore when using Git in conjunction with Xcode?

Based on this guide for Mercurial my .gitignore includes:

.DS_Store
*.swp
*~.nib

build/

*.pbxuser
*.perspective
*.perspectivev3

I've also chosen to include:

*.mode1v3
*.mode2v3

which, according to this Apple mailing list post, are "user-specific project settings".

And for Xcode 4:

xcuserdata

You should checkout gitignore.io for Objective-C and Swift.

Here is the .gitignore file I'm using:

# Xcode
.DS_Store
*/build/*
*.pbxuser
!default.pbxuser
*.mode1v3
!default.mode1v3
*.mode2v3
!default.mode2v3
*.perspectivev3
!default.perspectivev3
xcuserdata
profile
*.moved-aside
DerivedData
.idea/
*.hmap
*.xccheckout
*.xcworkspace
!default.xcworkspace

#CocoaPods
Pods

Mine is a .bzrignore, but it is the same idea :)

.DS_Store
*.mode1v3
*.pbxuser
*.perspectivev3
*.tm_build_errors

The tm_build_errors is for when I use TextMate to build my project. It is not quite as comprehensive as Hagelin, but I thought it was worth posting for the tm_build_errors line.

Here's the .gitignore that GitHub uses by default for new Xcode repositories:

https://github.com/github/gitignore/blob/master/Objective-C.gitignore

It's likely to be reasonably correct at any given time.

We did find that even if you add the .gitignore and the .gitattribte the *.pbxproj file can get corrupted. So we have a simple plan.

Every person that codes in office simply discards the changes made to this file. In the commit we simple mention the files that are added into the source. And then push to the server. Our integration manager than pulls and sees the commit details and adds the files into the resources.

Once he updates the remote everyone will always have a working copy. In case something is missing then we inform him to add it in and then pull once again.

This has worked out for us without any issues.
