Disabling Some Files in Xcode Project from Compilation

Xcode how to exclude FOLDERS from compilation?

From looking at the post you link to. Here is how you do it:

1. Go to Build Settings.

2. Press the plus button and select "Add User-Defined settings"

3. Give the new field the name of EXCLUDED_SOURCE_FILE_NAMES.

4. Add the path to the folder: <Path>/FolderToIgnore/*. The asterisk denotes all the file in the folder.

That should do it.

Note: Make sure you add this to the right target.

How can I disable ARC for a single file in a project?

It is possible to disable ARC for individual files by adding the -fno-objc-arc compiler flag for those files.

You add compiler flags in Targets -> Build Phases -> Compile Sources. You have to double click on the right column of the row under Compiler Flags. You can also add it to multiple files by holding the cmd button to select the files and then pressing enter to bring up the flag edit box. (Note that editing multiple files will overwrite any flags that it may already have.)

I created a sample project that has an example: https://github.com/jaminguy/NoArc
