"Warning: Error creating LLDB target at path ‘/***

I‘m getting this error whenever I build in Xcode 6 beta 4. It seems to be making my app insanely slow. What exactly does this mean and how do I fix it?

"Warning: Error creating LLDB target at path ‘/***/***/***/***.app‘- using an empty LLDB target which can cause slow memory reads from remote devices."

This warning is solved by changing Build Settings :

1. Select Project -> Build Settings

2. Change ‘Architectures‘ to ‘Standard architectures (armv7, arm64) - $(ARCHS_STANDARD)‘ 

3. This will prompt an alert stating iOS 5.1.1 and above are supported. Click ‘Change Deployment Target to 5.1.1‘

1. Repeat steps for Target (if not changed automatically)

Also, this is preferred build setting since Apple is forcing developers to build apps on 64 but architecture. Apple document Link
