I have been working on iOS for a long time now! Right after I decided to switch my company, I decided to brush up my iOS skills before I face an interview. So, I started googling stuff!! I was hoping to watch a couple of youtube videos on each topic to keep myself up to date. But as I did that, I found this amazing playlist on youtube from Sean Allen, who has made an amazing work of summarizing and sharing his 6-month job hunting experience in Bay Area in Youtube series. In this, he has covered most of basic topics in iOS with coding example. This is definitely a must watch playlist before you head for an iOS interview.
