Xcode 7 Beta 4/5 - New Playground EXC_BAD_ACCESS error

All I do is simply create a new playground in Xcode 7 beta 4 or 5 and I get the following error: Playground execution aborted: Execution was interrupted, reason: EXC_BAD_ACCESS (code=1, address=0x8).

Here is the error in the colsole:

I've had this issue since beta 4, and I thought it would get fixed in beta 5, but no luck.

Has anyone come across this problem? Or better yet, does anyone know what it is an how to overcome it?

Thanks.
