最新解决方案：把OSX El Capitan升级到Beta 7  (15A263e)，Xcode6可使用！

A workaround was found thanks to "lembacon" on the Apple Developer Forums.

In Terminal:

cd /Applications/Xcode-beta.app (or wherever your Xcode 7 beta 4 is located)  
cd Contents/Developer/Platforms/iPhoneSimulator.platform  
cd Developer/SDKs/iPhoneSimulator.sdk/usr/lib  
sudo mv dyld_sim dyld_sim.orig

Seems to work for iOS projects but watchOS is iffy.

EDIT: watchOS solution:

cd /Applications/Xcode-beta.app (or wherever your Xcode 7 beta 4 is located)  
cd Contents/Developer/Platforms/WatchSimulator.platform  
cd Developer/SDKs/WatchSimulator.sdk/usr/lib  
sudo mv dyld_sim dyld_sim.orig  

Another Edit: As mentioned by sciasxp, this also works for 6.4. Hopefully we'll get new iOS and Xcode betas soon that permanently fix this.

Another Another Edit: A new iOS beta is out today, as well as a new Xcode beta. This issue should be resolved.
