dyld: Library not loaded: @rpath/libswiftCore.dylib - Error in Xcode 7

I was working on Xcode 7 beta with Swift in a Mac mini (running Yosemite) Due to poor performance i installed Yosemite on my PC (like Hackintosh). And i copied the "xcode 7 beta.app" from 'applications' folder to my new pc's Yosemite.

Note: This question is already asked in stack overflow. But none of the solutions worked for me.

When i try to run the app in to my iPad i got an error like this. But no problem while running in emulator

(lldb) 

I searched a lot and find to method to fix it. But none of them worked for me.

1. 'Embedded content contains swift code' = Yes.
2. adding '@executable_path/Frameworks' to runpath.

Can someone pls tell me how can i fix this? Will reinstalling Yosemite/Xcode fix this? (I only have the .app file of xcode) Is there any other solution?

The issue is solved. I downloaded the new xcode 7 gm speed .dmg file from apple beta developers and installed. Now everything works fine
