title: App Store - Horizontal wheel app picker
body: <p>can you please give me a direction how to achieve similar app picker like we can see on top of App Store (check out a screenshot)? I assume we are talking about collection view with one row and customized cell's size etc. but I couldn't find any sample/tutorial/external library. </p>
