Here are utility script for Xcode development. Removing local project files from git repository, replacing Xcode header copyright description and ignoring Emacs's ^X^S keystroke to avoid mis-operation.

By default, when a new Xcode project is created with git repository, it adds local project files to git automatically. This is very annoying when we are developing the project with other engineers.

Executing xcode-remove-local-project-from-git.sh at the top directory of the project which includes .git will remove local project files such as below file from git repository.

${PROJECT}.xcodeproj/project.xcworkspace/contents.xcworkspacedata
${PROJECT}.xcodeproj/xcuserdata/${USER}.xcuserdatad/xcschemes/${PROJECT}.xcscheme
${PROJECT}.xcodeproj/xcuserdata/${USER}.xcuserdatad/xcschemes/xcschememanagement.plist

To run the script, please change directory to the top level of the Xcode project then execut xcode-remove-local-project-from-git.sh

$ cd ${ProjectDir}
$ xcode-remove-local-project-from-git.sh

This will automatically add .gitignore file to the current directory. Then removing local project files form git repository.

Xcode automatically insert header description using File Templates. Sometimes we want to customize the header description. xcode-copyright-replace.sh is for it.

Before executing the command, please check first part of the script.

#! /bin/sh
##
## Replace Xcode header template's copyright with ${COPYRIGHT}
##
#XCODE=Xcode
XCODE=Xcode6-Beta3

## Copyright string.
COPYRIGHT="Copyright (c) 2014 Enamel Systems. All rights reserved."

Please change XCODE and COPYRIGHT string accordingly. Then execute:

$ xcode-copyright-replace.sh

will replace the Header's copyright string. When you execute the command first time, you might to need the initialize git repository to keep original file. To do that please execute the command with -i option. Then you can execute xocode-copyright-replace.sh after that.

$ xcode-copyright-replace.sh -i
$ xcode-copyright-replace.sh

For emacs users, it is very common to press ^X^S keystroke during editiong. By default, Xcode puts strange character to the editing buffer. To avoid the mis-operation, Emacs.idekeybindings reassign ^X^S to "mark buffer" operation. To reflect the change, please copy Emacs.idekeybindings to ~/Library/Developer/Xcode/UserData/KeyBindings/.

$ cp Emacs.idekeybindings ~/Library/Developer/Xcode/UserData/KeyBindings/

Then Xcode->Preferences->Key Bindings menu, select Emacs from "Key Bindings Set" dropdown menu. After that you will see that ^X^S just mark the buffer.
