I\'m getting this error whenever I build in XCode 6 beta 4. It seems to be making my app insanely slow.
Warning: Error creating LLDB
This warning is solved by changing Build Settings :
Change 'Architectures' to 'Standard architectures (armv7, arm64) - $(ARCHS_STANDARD)'
This will prompt an alert stating iOS 5.1.1 and above are supported. Click 'Change Deployment Target to 5.1.1'
Also, this is preferred build setting since Apple is forcing developers to build apps on 64 but architecture. Apple document Link
