Swift Talk ($)
Chris Eidhof and Florian Kugler of objc.io fame publishes a weekly video podcast where they pair program live and talk about Swift. They have a really nice and humble style where they start off each episode by describing a common problem, and then alternate sitting in the front seat and help each other solve the problem, gradually evolving it and discussing improvements along the way. The show is subscription based and costs money, but I recommend spending a few euros on them
Another weekly video cast from another great guy.
