After that, you can just augment&nbsp;<strong>Step 5<\/strong>&nbsp;to make your UIView slide.<\/p>\n\n\n\n<p><strong>Side Note<\/strong>: What\u2019s different from this and the previous tutorials are the constraints that I added to the UIView. However, it doesn\u2019t really matter\u2026 \ud83d\ude42<\/p>\n\n\n\n<p><strong>Step 5: Add code to slide<\/strong>&nbsp;In this example, we\u2019re adding animation to slide a&nbsp;<code>UIView<\/code>&nbsp;once the app loads. To do that, we\u2019ll create a function, then call that function within the&nbsp;<code>viewDidLoad<\/code>&nbsp;lifecycle function.<\/p>\n\n\n\n<p>This is the function that contains the animation.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>func beginAnimation () {\n  \/\/ 1st transformation\n  self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, -100)\n\n  UIView.animateWithDuration(0.4, delay: 0, options: &#91;.CurveEaseInOut], animations: {\n      \/\/ 2nd transformation\n      self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, 50)\n      }, completion: { completion in\n          UIView.animateWithDuration(0.2, delay: 0.0, options: &#91;.CurveEaseInOut], animations: {\n              \/\/ 3rd transformation\n              self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, 0)\n          }, completion: nil)\n  })\n}<\/code><\/pre>\n\n\n\n<p>In this example, I\u2019ve got 3 transformations because the animation that I\u2019m going for is a slide+little bump+short slide to position.<\/p>\n\n\n\n<p>The first transformation is the starting position, and here, I\u2019ve got it set above the visible viewport at&nbsp;<code>-100<\/code>.<\/p>\n\n\n\n<p><code>self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, -100)<\/code><\/p>\n\n\n\n<p>The second transformation brings the UIView into the view, and with the \u201c.CurveEaseInOut\u201d option will give this a snappiness at&nbsp;<code>50<\/code>.<\/p>\n\n\n\n<p><code>self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, 50)<\/code><\/p>\n\n\n\n<p>And finally, the third transformation, I have it in the completion block, and this will bring the UIView up and make it look like it \u201cbumps\u201d into it\u2019s final position at&nbsp;<code>0<\/code>.<\/p>\n\n\n\n<p><code>self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, 0)<\/code><\/p>\n\n\n\n<p>Add the code in your&nbsp;<code>viewDidLoad<\/code>&nbsp;to start the pulse<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>self.beginAnimation()<\/code><\/pre>\n\n\n\n<p>Your file should look similar to this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>import UIKit\n\nclass ViewController: UIViewController {\n  @IBOutlet weak var uiViewToSlide: UIView!\n\n  override func viewDidLoad() {\n    super.viewDidLoad()\n    \/\/ Do any additional setup after loading the view, typically from a nib.\n    self.beginAnimation()\n  }\n\n  override func didReceiveMemoryWarning() {\n    super.didReceiveMemoryWarning()\n    \/\/ Dispose of any resources that can be recreated.\n  }\n\n  func beginAnimation() {\n    self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, -100)\n\n    UIView.animateWithDuration(0.4, delay: 0, options: &#91;.CurveEaseInOut], animations: {\n      self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, 50)\n      }, completion: { completion in\n        UIView.animateWithDuration(0.2, delay: 0.0, options: &#91;.CurveEaseInOut], animations: {\n          self.uiViewToSlide.transform = CGAffineTransformMakeTranslation(0, 0)\n        }, completion: nil)\n    })\n\n  }\n}<\/code><\/pre>\n\n\n\n<p>And that should be it.
