I have discovered that there are no official online video tutorials in Swift or Objective-C from Apple. I mean, of course, there are lots of WWDC sessions, however, there are no video with 6-15 minutes length on YouTube (or any other platform). For example, Microsoft's dotNET YouTube account has lots of playlists to start learning their technology. Why apple do not distribute these kinds of their own (by Apple) video tutorials?
Maybe the core team should create official Swift youtube channel, and make some live streams regularly engaged with communities.
And if they make tutorials, I hope they script them well, and then put the scripts and graphics online as well, because I hate the pacing of most video tutorials, though I understand not everyone has my preferences.
Totally agree with you that would be awesome!
May be they can open source the tutorials as well.
