In terms of topic I would love to see. I am more interested in videos that might teach design and architecture. For example
- Caching strategy and architecture for data off the internet, including memory based cache along with file based cache.
- Cache/saving of state for app to survive segue unwinds/app sent to background/app closed
- View controller re-use and strategies to manage large apps with many view controllers and a lot of inter-view controller transitions.
