iOS多人开发中的gitignore问题

多人项目中提交代码时，很多用户信息是不需要上传，可以保证代码提交最整洁。

git中有一个非常牛的文件(.gitignore)，有了这个文件，每次本地仓储发生变更时，在这个文件内目录或者文件，即使内容变化也不会被监控，保证开发在git add时，不添加这些变更。

那么，iOS开发中的.gitignore文件如何撰写内容呢？这里有个比较通用的答案：

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

# Xcode

#

# gitignore contributors: remember to update Global/Xcode.gitignore, Objective-C.gitignore & Swift.gitignore

## Build generated

build/

DerivedData/

## Various settings

*.pbxuser

!default.pbxuser

*.mode1v3

!default.mode1v3

*.mode2v3

!default.mode2v3

*.perspectivev3

!default.perspectivev3

xcuserdata/

## Other

*.moved-aside

*.xcuserstate

## Obj-C/Swift specific

*.hmap

*.ipa

*.dSYM.zip

*.dSYM

# CocoaPods

#

# We recommend against adding the Pods directory to your .gitignore. However

# you should judge for yourself, the pros and cons are mentioned at:

# https://guides.cocoapods.org/using/using-cocoapods.html#should-i-check-the-pods-directory-into-source-control

#

# Pods/

# Carthage

#

# Add this line if you want to avoid checking in source code from Carthage dependencies.

# Carthage/Checkouts

# fastlane

#

# It is recommended to not store the screenshots in the git repo. Instead, use fastlane to re-generate the

# screenshots whenever they are needed.
