How can i use different source files with same class name in Xcode for mocking?

Question

My Xcode project contains two target:

• main that contain the main source code
• uiTest that contain code for ui testing

So it has a file called DIResolver that used to provide my dependencies. When i build main target it works fine but when i start UI tests i need to mock some dependencies.

The main question is: can i use the same filename in two different place (real and mock for example) resolving by scheme and how?
