How can I load storyboard programmatically from class

Question

My problem is that I was looking for way to use both storyboard and xib  But I can t find proper way to load and show storyboard programmatically  Project was started developing with xib  and now it s very hard to nest all xib files in storyboard  So I was looking a way to do it in code  like with alloc  init  push for viewControllers  In my case I have only one controller in storyboard  UITableViewController  which has static cells with some content I want to show  If anyone knows proper way to work both with xib and storyboard without huge refactoring  I will appreciate for any help

In your storyboard go to the Attributes inspector and set the view controller s Identifier  You can then present that view controller using the following code   UIStoryboard  sb    UIStoryboard storyboardWithName   MainStoryboard  bundle nil   UIViewController  vc    sb instantiateViewControllerWithIdentifier   myViewController    vc modalTransitionStyle   UIModalTransitionStyleFlipHorizontal   self presentViewController vc animated YES completion NULL

For swift 3 and 4  you can do this  Good practice is set name of Storyboard equal to StoryboardID   enum StoryBoardName     case second    SecondViewController    extension UIStoryBoard     class func load   storyboard  StoryBoardName  - gt  UIViewController        return UIStoryboard name  storyboard rawValue  bundle  nil  instantiateViewController withIdentifier  storyboard rawValue           and then you can load your Storyboard in your ViewController like this   class MyViewController  UIViewController       override func viewDidLoad             super viewDidLoad           guard let vc   UIStoryboard load  second  as  SecondViewController else  return          self present vc  animated  true  completion  nil              When you create a new Storyboard just set the same name on StoryboardID and add Storyboard name in your enum  StoryBoardName
