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.

For swift 4 and 5, 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) -> 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"

The extension below will allow you to load a Storyboard
and it's associated UIViewController
. Example: If you have a UIViewController
named ModalAlertViewController
and a storyboard named "ModalAlert" e.g.
let vc: ModalAlertViewController = UIViewController.loadStoryboard("ModalAlert")
Will load both the Storyboard
and UIViewController
and vc
will be of type ModalAlertViewController
. Note Assumes that the storyboard's Storyboard ID has the same name as the storyboard and that the storyboard has been marked as Is Initial View Controller.
extension UIViewController {
/// Loads a `UIViewController` of type `T` with storyboard. Assumes that the storyboards Storyboard ID has the same name as the storyboard and that the storyboard has been marked as Is Initial View Controller.
/// - Parameter storyboardName: Name of the storyboard without .xib/nib suffix.
static func loadStoryboard<T: UIViewController>(_ storyboardName: String) -> T? {
let storyboard = UIStoryboard(name: storyboardName, bundle: nil)
if let vc = storyboard.instantiateViewController(withIdentifier: storyboardName) as? T {
vc.loadViewIfNeeded() // ensures vc.view is loaded before returning
return vc
}
return nil
}
}

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "viewController")
self.navigationController!.pushViewController(vc, animated: true)
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("viewController")
self.navigationController!.pushViewController(vc, animated: true)
Prerequisite
Assign a Storyboard ID to your view controller.
IB > Show the Identity inspector > Identity > Storyboard ID
Swift (legacy)
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("viewController") as? UIViewController
self.navigationController!.pushViewController(vc!, animated: true)
Edit: Swift 2 suggested in a comment by Fred A.
if you want to use without any navigationController you have to use like following :
let Storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = Storyboard.instantiateViewController(withIdentifier: "viewController")
present(vc , animated: true , completion: nil)

You can always jump right to the root controller:
UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *vc = [storyboard instantiateInitialViewController];
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:vc animated:YES completion:NULL];

in swift
NavigationController and pushController you can replace for
present(vc, animated:true , completion: nil)

Try this
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:@"Login"];
[[UIApplication sharedApplication].keyWindow setRootViewController:vc];

In attribute inspector give the identifier for that view controller and the below code works for me
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
DetailViewController *detailViewController = [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];
[self.navigationController pushViewController:detailViewController animated:YES];

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];
