Apple employees blogging about something publicly is not a usual occurrence, but thats whats happening with engineers who have built Swift, the companys new programming language. Today the company quietly launched a new blog for Swift that promises to bring a behind-the-scenes look into the design of the programming language by the engineers who created it. So far, there are just two posts: one introducing the blog, and another that goes into some detail about the programming languages compatibility. Alongside the move, Apples done away with the need to be a paid member of its iOS or Mac developer programs in order to download a beta version of Xcode 6, which lets programmers make Swift-based projects.
