大多数答案都来自Xcode 4-5时代。我建议使用现代风格的ignore文件。

# Xcode Project
**/*.xcodeproj/xcuserdata/
**/*.xcworkspace/xcuserdata/
**/.swiftpm/xcode/xcuserdata/
**/*.xcworkspace/xcshareddata/IDEWorkspaceChecks.plist
**/*.xcworkspace/xcshareddata/*.xccheckout
**/*.xcworkspace/xcshareddata/*.xcscmblueprint
**/*.playground/**/timeline.xctimeline
.idea/

# Build

*.ipa

# Carthage

# CocoaPods

请从https://github.com/BB9z/iOS-Project-Template/blob/master/.gitignore更新

我使用以下在gitignore.io中生成的.gitignore文件:

### Xcode ###
build/
*.pbxuser
!default.pbxuser
*.mode1v3
!default.mode1v3
*.mode2v3
!default.mode2v3
*.perspectivev3
!default.perspectivev3
xcuserdata
*.xccheckout
*.moved-aside
DerivedData
*.xcuserstate


### Objective-C ###
# Xcode
#
build/
*.pbxuser
!default.pbxuser
*.mode1v3
!default.mode1v3
*.mode2v3
!default.mode2v3
*.perspectivev3
!default.perspectivev3
xcuserdata
*.xccheckout
*.moved-aside
DerivedData
*.hmap
*.ipa
*.xcuserstate

# CocoaPods
#
# We recommend against adding the Pods directory to your .gitignore. However
# you should judge for yourself, the pros and cons are mentioned at:
# http://guides.cocoapods.org/using/using-cocoapods.html#should-i-ignore-the-pods-directory-in-source-control
#
Pods/

基于Mercurial的这个指南，我的.gitignore包括:

.DS_Store
*.swp
*~.nib

build/

*.pbxuser
*.perspective
*.perspectivev3

我还选择了包括:

*.mode1v3
*.mode2v3

根据苹果邮件列表，这是“用户特定的项目设置”。

对于Xcode 4:

xcuserdata

我的是一个。bzrignore，但它是相同的想法:)

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

tm_build_errors用于当我使用TextMate构建我的项目时。它没有Hagelin那么全面，但我认为值得在tm_build_errors行中发布它。

你应该结账给gitignore。用于Objective-C和Swift。

下面是我正在使用的.gitignore文件:

# 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

关于“build”目录排除-

如果您将构建文件放在与源文件不同的目录中，就像我所做的那样，您不必担心树中的文件夹。

这也使得共享代码变得更加简单，防止臃肿的备份，甚至当你依赖于其他Xcode项目时(同时要求构建彼此位于相同的目录中)。

你可以从Github gist https://gist.github.com/708713获取最新的拷贝

我当前的。gitignore文件是

# Mac OS X
*.DS_Store

# Xcode
*.pbxuser
*.mode1v3
*.mode2v3
*.perspectivev3
*.xcuserstate
project.xcworkspace/
xcuserdata/

# Generated files
*.o
*.pyc


#Python modules
MANIFEST
dist/
build/

# Backup files
*~.nib
