import UIKit

enum SegueIdentifier:String {
    case LogIn = "logInViewSegue"
    case Home = "homeViewSegue"
    case Profile = "profileViewSegue"
    case Search = "searchViewSegue"
    case Signature = "signatureViewSegue"
}

extension UIStoryboard {
    class func mainStoryBoard() -> UIStoryboard { return UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())}
    
    class func loginController() -> LogInViewController? {
        return mainStoryBoard().instantiateViewControllerWithIdentifier("LogInViewController") as? LogInViewController
    }
}

//  UIViewController+Extensions.swift
extension UIViewController {
    func performSegueWithIdentifier(identifier: SegueIdentifier, sender: AnyObject?) {
        self.performSegueWithIdentifier(identifier.rawValue, sender: self)
    }
}


//Sample usecase
self.performSegueWithIdentifier(.LogIn, sender: self)
self.performSegueWithIdentifier(.Search, sender: self)
self.performSegueWithIdentifier(.Profile, sender: self)

Wouldn't it be cool to have an @IBDesignable extension that can provide us with a list of SegueIdentifiers to choose from?
