UIStoryboard Extension for Easy Instantiate Viewcontrollers [Swift]

UIStoryboard+Extensions.swift

enum Storyboard: String {
    case main = "Main",
    onboarding = "Onboarding"
}

protocol Instantiatable {
    static var storyboard: Storyboard { get }
    static func instantiate() -> Self
}

extension Instantiatable where Self: UIViewController {
    static func instantiate() -> Self {
        // swiftlint:disable force_cast
        UIStoryboard(storyboard).instantiateViewController(withIdentifier: String(describing: Self.self)) as! Self
    }
}

extension UIStoryboard {
    convenience init(_ storyboard: Storyboard) {
        self.init(name: storyboard.rawValue, bundle: nil)
    }
}

// Usage:
class ViewController: UIViewController, Instantiatable {
	static var storyboard: Storyboard = .main
}
// Get Instance by:
let vc = ViewController.instantiate()

@lalkrishna Here for eq. I have to jump to ProfileVC which is in profile storyboard as well on ChatVC which is in chat storyboard. How do I achieve this?

You have to declare both storyboard in struct and, each VC should conforms to Instantiatable protocol.

class ProfileVC: UIViewController, Instantiatable {
	static var storyboard: Storyboard = .profile
}
class ChatVC: UIViewController, Instantiatable {
	static var storyboard: Storyboard = .chat
}
let viewController = ProfileVC.instantiate()
navigationController?.pushViewController(viewController, animate: true)
