64-bit Eclipse for OSX

Grab the 64-bit SWT binaries from that installation. You are in luck that they finally decided to create a 64-bit SWT binary for OSX, they had previously claimed they never would.

plugins/org.eclipse.swt.cocoa.macosx.x86_64_3.6.1.v3655c.jar (The version on the end will be different) should contain what you want.

Also from a pragmatic point of view realize that Apple has End of Lifed their JVM on OS X. They want nothing to do with Java but that is a different debate. From my understanding the good folks that work on OpenJVM have it working on OS X.

SWT has native code. So you have to build your package to target the precise target you are aiming for. I'm sort of amazed that you only got a 32 versus 64-bit error, I'd expect almost that it would try to load the Windows DLLs!

You need to configure SWT to target the 64-bit MacOS JVM. If you're using RCP, you need different OSGi fragments. If you are using native SWT, you need to work at that level.

Some of what you need to know exists in a prior question/answer, see:

Create cross platform Java SWT Application
