The current issue of the PragPub Magazine is heavily focus on Swift. From what I’ve been told, their purchasing handling server was so overwhelmed that some of the emails to notify readers of the download links was not sent out. It seems this is one of the most popular issue they’ve published.
It’s $1.99 for a single issue or $19.99 for a one-year subscription. If you are interested in Swift, I recommend you at least get the current issue.
