Let's take a quick little breather from feature implementations to fix a few bugs we introduced in the last episode. While we are now able to post photos, we have a few problems rendering them correctly inside of our <b>UserProfileController</b>. I'll first go over what the issues are regarding the <b>UICollectionView.reloadData()</b> method. Next we dive into the proper fix of url checking in our image loading process. Finally, I'll go into the fix of ordering our <b>Posts</b> as well as reloading our list every time a new post is uploaded.
