This fixes the problem with the interface builder.

 cd /Applications/Xcode.app cd Contents/Developer/Platforms/iPhoneSimulator.platform cd Developer/SDKs/iPhoneSimulator.sdk/usr/lib sudo mv dyld_sim dyld_sim.orig

According to @ThePaddedCell, I took the following steps, it finally worked for me

1) Move xcode6-beta to the application folder

2) Restart mac and open xcode6-beta from the application folder.

but I don’t know why .. If anyone knows this reason, welcome to update my answer.
