hey Brian,
Thanks for the course, I'm developing a similar application, but the fee layout is only as instagram stories present full post may be image or video, I solved with a collectionView and load the images or video with alamofire and works well, however I need start to fill the progress bar when the post already was loaded not before when Cell is visible and waiting for download, each cell take his respective time if is photo 10 seconds, if is video time of the video, I hope same way as instagram, change to next CELL when time is finish (progress bar is full), and begin the same again.
I use the notification center to notify that images is download but is async work so not always the notification correspond to the current CELL, hence start to fill the progressbar and the current cell not finished to load, beacuse post the notification that already downloaded one image of other cell (almost the next cell) , this make that the current cell start his progress bar and change to next cell, and dont display the current post or a bit of real time if load when progressbar started.
Recently I found IGListKIt, but is not clear to me the implmentation and if could help to me, I hope be clear with the problem, thanks in advance.
