Swift 2.0:

1)

//  AppDelegate.swift

import UIKit
import Foundation

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate {

 var window: UIWindow?
 var splashTimer:NSTimer?
 var splashImageView:UIImageView?

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  window = UIApplication.sharedApplication().delegate!.window!

  let splashImage: UIImage = UIImage(named: "ic_120x120.png")!
  splashImageView = UIImageView(image: splashImage)
  splashImageView!.frame = CGRectMake(0, 0, (window?.frame.width)!, (window?.frame.height)!)

  window!.addSubview(splashImageView!)
  window!.makeKeyAndVisible()

  //Adding splash Image as UIWindow's subview.
  window!.bringSubviewToFront(window!.subviews[0])

  // Here specify the timer.
  splashTimer = NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "splashTimerForLoadingScreen", userInfo: nil, repeats: true)

  return true
 }
 func splashTimerForLoadingScreen() {
  splashImageView!.removeFromSuperview()
  splashTimer!.invalidate()
 }

2)

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  NSThread.sleepForTimeInterval(9)

  OR

  sleep(9)

  return true
 }

3) Использование концепции контроллера корневого представления:

//  AppDelegate.swift

import UIKit
import Foundation

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate {

 var window: UIWindow?
 var splashTimer:NSTimer?
 var storyboard:UIStoryboard?

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  window =  UIWindow(frame: UIScreen.mainScreen().bounds)
  window?.makeKeyAndVisible()

  storyboard = UIStoryboard(name: "Main", bundle: nil)

  //Here set the splashScreen VC
  let rootController = storyboard!.instantiateViewControllerWithIdentifier("secondVCID")

  if let window = self.window {
   window.rootViewController = rootController
  }

  //Set Timer
  splashTimer = NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "splashTimerCrossedTimeLimit", userInfo: nil, repeats: true)

  return true
 }
 func splashTimerCrossedTimeLimit(){

  //Here change the root controller
  let rootController = storyboard!.instantiateViewControllerWithIdentifier("firstVCID")
  if let window = self.window {
   window.rootViewController = rootController
  }
  splashTimer?.invalidate()
 }
