Duplicate and rename Xcode project & associated folders

Question

I would like to be able to duplicate an entire Xcode project, rename the project and the associated files without Xcode going mental, and without having to manually re-import all files to the project.

This answer is the culmination of various other StackOverflow posts and tutorials around the internet brought into one place for my future reference, and to help anyone else who may be facing the same issue. All credit is given for other answers at the end.

Duplicating an Xcode Project

• In the Finder, duplicate the project folder to the desired location of your new project. Do not rename the .xcodeproj file name or any associated folders at this stage.

• In Xcode, rename the project. Select your project from the navigator pane (left pane). In the Utilities pane (right pane) rename your project, Accept the changes Xcode proposes.

• In Xcode, rename the schemes in "Manage Schemes", also rename any targets you may have.

• If you're not using the default Bundle Identifier which contains the current PRODUCT_NAME at the end (so will update automatically), then change your Bundle Identifier to the new one you will be using for your duplicated project.

Renaming the source folder

So after following the above steps you should have a duplicated and renamed Xcode project that should build and compile successfully, however your source code folder will still be named as it was in the original project. This doesn't cause any compiler issues, but it's not the clearest file structure for people to navigate in SCM, etc. To rename this folder without breaking all your file links, follow these steps:

• In the Finder, rename the source folder. This will break your project, because Xcode won't automatically detect the changes. All of your xcode file listings will lose their links with the actual files, so will all turn red.

• In Xcode, click on the virtual folder which you renamed (This will likely be right at the top, just under your actual .xcodeproject) Rename this to match the name in the Finder, this won't fix anything and strictly isn't a required step but it's nice to have the file names matching.

• In Xcode, Select the folder you just renamed in the navigation pane. Then in the Utilities pane (far right) click the icon that looks like dark grey folder, just underneath the 'Location' drop down menu. From here, navigate to your renamed folder in the finder and click 'Choose'. This will automagically re-associate all your files, and they should no longer appear red within the Xcode navigation pane.

• In your project / targets build settings, search for the old folder name and manually rename any occurrences you find. Normally there is one for the prefix.pch and one for the info.plist, but there may be more.

• If you are using any third party libraries (Testflight/Hockeyapp/etc) you will also need to search for 'Library Search Paths' and rename any occurrences of the old file name here too.

• Repeat this process for any unit test source code folders your project may contain, the process is identical.

This should allow you to duplicate & rename an xcode project and all associated files without having to manually edit any xcode files, and risk messing things up.

Answer 2

I'm posting this since I have always been struggling when renaming a project in XCode.

Renaming the project is good and simple but this doesn't rename the source folder. Here is a step by step of what I have done that worked great in Xcode 4 and 5 thanks to the links below.

REF links:
Rename Project.
Rename Source Folder and other files.

1- Backup your project.

If you are using git, commit any changes, make a copy of the entire project folder and backup in time machine before making any changes (this step is not required but I highly recommended).

2- Open your project.

3- Slow double click or hit enter on the Project name (blue top icon) and rename it to whatever you like.

NOTE: After you rename the project and press ‘enter’ it will suggest to automatically change all project-name-related entries and will allow you to de-select some of them if you want. Select all of them and click ok.

4- Rename the Scheme

a) Click the menu right next to the stop button and select Manage Schemes.

b) Single-slow-click or hit enter on the old name scheme and rename it to whatever you like.

c) Click ok.

5 - Build and run to make sure it works.

NOTES: At this point all of the important project files should be renamed except the comments in the classes created when the project was created nor the source folder. Next we will rename the folder in the file system.

6- Close the project.

7- Rename the main and the source folder.

8- Right click the project bundle .xcodeproj file and select “Show Package Contents” from the context menu. Open the .pbxproj file with any text editor.

9- Search and replace any occurrence of the original folder name with the new folder name.

10- Save the file.

11- Open XCode project, test it.

12- Done.

There is a tool to rename projects in Xcode I haven't tried it enough to comment on it. https://github.com/appculture/xcode-project-renamer

Answer 3

As of XCode 7 this has become much easier.

Apple has documented the process on their site: https://developer.apple.com/library/ios/recipes/xcode_help-project_editor/RenamingaProject/RenamingaProject.html

Update: XCode 8 link: http://help.apple.com/xcode/mac/8.0/#/dev3db3afe4f

Answer 4

I am using this script after I rename my iOS Project. It helps to change the directories name and make the names in sync.

http://github.com/ytbryan/rename

NOTE: you will need to manually change the scheme's name.

Answer 5

In the example code for the book "Instant OpenCV for iOS" I have found a bash script that copies a project from a folder to another.
Doing a little research I've found a blog post from what seems to be the original author of the script: http://mohrt.blogspot.it/2009/01/renaming-xcode-project-from-command.html, where you can download the script. I gave it a try and running it from terminal like this

    sh renameXcodeProject.sh <name-of-existing-folder> <name-of-folder-to-create>   

works fine.
Additional info can be found opening the file with a text editor. Hope that helps

Answer 6

I using Xcode 6+ and I just do:

• Copy all files in project folders to new Folders (with new name).
• Open *.xcodeproj or *.xcworkspace
• Change name of Project.
• Click on schema and delete current chema and add new one.

Here is done, but name of window Xcode and *.xcodeproj or *.xcworkspace still <old-name>. Then I do:

• pop install
• Open <new name>.xcworkspace

Answer 7

One more thing to try!

When I copied all of my files, opened the project, and renamed it, everything changed to my new project name except for the test target! I got a linker error that said I was missing a file called "myOldProjectname.app". Here's what fixed it:

1. Click on your project settings and select your test target

2. Click on build settings and search for "test host"

3. Check those 2 file paths. Chances are that those 2 paths are still pointing at your old project name.

Hope that helps!

Answer 8

For anybody else having issues with storyboard crashes after copying your project, head over to Main.storyboard under Identity Inspector.

Next, check that your current module is the correct renamed module and not the old one.

Answer 9

I'm using simple BASH script for renaming.

Usage: ./rename.sh oldName newName

#!/bin/sh

OLDNAME=$1
NEWNAME=$2

export LC_CTYPE=C 
export LANG=C
find . -type f ! -path ".*/.*" -exec sed -i '' -e "s/${OLDNAME}/${NEWNAME}/g" {} +

mv "${OLDNAME}.xcodeproj" "${NEWNAME}.xcodeproj"
mv "${OLDNAME}" "${NEWNAME}"

Notes:

1. This script will ignore all files like .git and .DS_Store
2. Will not work if old name/new name contains spaces
3. May not work if you use pods (not tested)
4. Scheme name will not be changed (anyway project runs and compiles normally)
