In this tutorial you will learn how to make a flixel project using Xcode.
The resulting project is what you get by using flx.py , but ready to be used in Xcode.
I assume you already have Flixel and Flex installed.

1 – Download the template
Download

2 – Install the template
extract the archive and put it in

/Developer/Library/Xcode/Project Templates/Other

3 – Set the path to mxmlc

• Open the template by double clicking the “Template.xcodeproj” file
• In Targets, double-click “mxmlc”
• write the path to your flex sdk directory in the “Build Tool” field
  By default I set it to
  

  /usr/local/flex_sdk_3.4/bin/mxmlc

  
  If you have it in a different place change it to your location.

4 – Add Flixel

• right-click your project in the side bar and selec “add → Existing Files…”
• Select the “org” folder of flixel and click add.
• Check the “Copy items into desitnation group’s folder (if needed)” checkbox.
• Also select “Create Folder References for any added folder”
• Close this project

5 – Create your project
Now that we have the template setup, it’s time to create a project.

• click “File → New Project” or cmd-shift-n
• give a name to your project and put it where you want

6 – Adapt the code to your project’s name

• Rename “Template.as” to the name of your project
• In the renamed file, change the two “PROJECT_NAME” to the name you just gave to the file.
• Open “Preloader.as” and do the same thing
• Double-click mxmlc under “Targets” go under “Custom Build Command” → “Arguments” in the right column and replace “$(PROJECT_NAME)” with your project name.

7 – Build
It’s finally time to build!

• click “Build → Build” or just press cmd-b
  If there are no errors, you should now have a swf file in your projects folder.

Optional — If you would like to be able to launch your game’s swf with XCode’s built-in Run feature, follow these steps in your project:

• Right click on “Executables”, select “Add” and select “New Custom Executable”.
• In the following window, for Executable Name, rename “Executable” to “open”. Set the Executable Path to “/usr/bin/open”
• In the Executable Info window, set the Path Type to Absolute Path, and then select the Arguments pane. Click the + in the Arguments section to add an argument.
• Set the argument to: “/The Full Path to your Project Directory/YourGameName.swf”

Now you will be able to use XCode’s Run feature (Cmd-R) to build and launch your executable. Make sure you have Adobe’s standalone Flash Player installed and set to open .swf files.
