Last week, I recorded an episode of .Net Rocks about what it's like learning Apple's new Swift language. I think it went well enough, although I wish I could go 10 seconds without saying "you know", and I did go into the weeds giving my impressions of what motivates Apple.
An hour is just not long enough for the topic, and we only just did a very impressionistic coverage of the language.
Regardless, I thought it went fairly well, and worth the time to listen to.
