XCode 7 is freezing and keep using more and more Memory when compiles Swift Project

After converted from Swift 1.2 to 2.0, It's just freezing when i compile the project and it's keep consumming memory.

I tried clean project, delete derived data, close XCode and restart my Mac but the problem still remains.

Anyone has the same problem as mine?
