Multiple View Controller in Storyboard

Could someone tell me how use multiple view controllers in storyboard and connecting them together ?
and Coding in each view controller, how to make a view file for each. Working with buttons to change view.

If possible could you be quite specific.

Thank You

There is no simple answer to a such a broad question.

You really need to take on a course that takes you through the basics of Xcode and gradually build on that knowledge base to expand on how to operate with multiple view controllers. The techniques take time to learn. Chris has a number of beginner videos that will help you. Have a look at this 28 day challenge on his website:
