IOS Swift controller opening with objective-c view .m file

I have a Facebook login screen based on Objective-C code and xib file for frontend. After creating the access token, I want to open the following Swift based screen. Someone please help me how can I open a quick access controller from an Objective-C view controller. When I write the name of the view controller, xcode never recognizes. Googled from yesterday but didn't get much success. Please, help:)
