Stacktrace podcast ("life and technology from two developers' perspective") had the cohosts, Gui Rambo and John Sundell, featured yours truly - to one extent or another.
As part of the regular Ask Stacktrace part of the podcast, they answered a question I sent them. The question was about converting to become a Swift developer given an old style development background in C and assembly.
The answer - which is excellent, in my opinion, and definitely reflects my own personal experience - can be heard at the last 5 minutes or so of the podcast. You can listen to the entire episode, the question, and the answer here.
