title: "Spotify like" dragging bottom player in swift
body: <p>I would like to have a bar/button at the bottom of my screen that behaves like the  mini player bar on Spotify. If I click on it, a view appears from the bottom. If I drag it, I can play with it and make it go up and down. And if I release it, it continues up by itself.</p>
  
  <p>I checked that question: <a href="https://stackoverflow.com/questions/30881214/how-to-animate-an-object-vertically-with-touch-like-spotifys-music-player-does">How to animate an object vertically with touch like Spotify&#39;s music player does when tapping the song,</a> but it only resizes an (image) view where I want to put a new ViewController (and I cannot drag it, only click it).</p>
  
  <p>I found a project that does that: <a href="https://github.com/andriirogulin/ARSlidingPanel" rel="nofollow noreferrer">https://github.com/andriirogulin/ARSlidingPanel</a> and it looks like it works pretty well. It is really something like that that I want to achieve.</p>
  
  <p>My problem is that I have almost no knowledge of objective-C. Moreover I tried to follow the Integration tutorial and I cannot add a custom segue from ARSPContainerController. I need to drague it from an object, and there is none in the sample project. Therefore I would like to know if:</p>
  
  <ol>
  <li>there is a name for this kind of specific bottom bar (for easier research purposes) and the way I would like to use it.</li>
  <li>there is a Pod/project that does that in swift.</li>
  <li>someone has a sample project that has this behaviour?</li>
  </ol>
