Как использовать приложение написанное на Objective-C++ из swift приложения?

Всем привет! Подскажите кто знает.

Есть старое игра написание на Objective-C + C++. Все игра состоит из main.h main.mm и ресурса с изображениями. На текущий момент мне необходмо вставить код (написаный на swift) который необходимо вставить перед запуском игры. Как использовать приложение написанное на Objective-C++ из swift приложения?

main.h
