I am having a similar problem:

The HelloWorldSWT tutorial does not work for me.

I am using a brand new out-of-the-box MacBookPro with Retina Display, 13", with i7.
My library is org.eclipse.swt,cocoa.macosx.x86

The following errors appear in the console when trying to compile:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
no swt-cocoa-4234 in java.library.path
no swt-cocoa in java.library.path
Can't load library: /Users/Nafty/.swt/lib/macosx/x86_64/libswt-cocoa-4234.jnilib

The tutorial instructions still leave out adding the SWT jar to the project libraries. Here's one way to do it.
Right click your project, choose Properties.
Select Java Build Path.
Select the Libraries tab and click the 'Add External Jars' button.
Now find your eclipse installation folder, /pathtoeclipse/eclipse, and drill down into the 'plugins' folder.
Find and highlight the org.eclipse.swt.[os].[arch].v4233d.jar file and click OK (or Open as the case may be).

Now you have a referenced libraries entry for the swt jar in your project and you should be able to run HelloWorldSWT.

Here's another way to add the reference - http://www.mkyong.com/swt/how-to-import-swt-library-into-eclipse-workspace/
