Which files in my iOS Xcode project should I hide before uploading to github?

Question

In Ruby on Rails , I know there's a config/secrets.yml file which I shouldn't upload to github .

Is there anything equivalent in an iOS app? I'm thinking about uploading my app to github before submitting it to the Apple app store, and I don't want to accidentally share any secret keys or anything else that should remain private.

GitHub maintains a public project with the .gitignore recommendations for several languages: https://github.com/github/gitignore

For XCode this is how the file looks :

# 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
*.xccheckout
*.moved-aside
*.xcuserstate
*.xcscmblueprint

## Obj-C/Swift specific
*.hmap
*.ipa

# 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-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

Carthage/Build

Answer 2

This is what I've been using for a .gitignore file in a few projects:

# Exclude temp nibs and swap files
*~.nib
*.swp

# Exclude OS X folder attributes
.DS_Store
.svn

# Exclude user-specific XCode 3 and 4 files
*.mode1
*.mode1v3
*.mode2v3
*.perspective
*.perspectivev3
*.pbxuser
*.xcworkspace
xcuserdata

I think that handles Xcode's user-specific local project files and OS X temp files, while preserving everything you need for a project to build straight from the repository.
