How to access Objective-C and Swift classes from one storyboard?

I implemented one class based on UIButton (RoundButton) in Swift, and the rest are still in Objective-C. How to access classes with Objective-C and Swift classes in one storyboard?

You can enter RoundButtonthe UIButton Custom Class - Classin the storyboard, but iOS gives the following warning:

Unknown class RoundButton in Interface Builder file.
