Tests with Quick and Nimble

I installed Quick and Nimble frameworks for tests in Swift. But inside test class my class' types is unresolved. In the top of test class I make imports:

import UIKit
import Nimble
import Quick
import MyProject

I know my main target should be at target dependencies and no classes files (except test classes) should be added to compile sources of test target.

Why my files is not visible in test target?
