Swift @ IBM
For those interested in learning more about Swift there are a couple of blogs that are worth keeping an eye on. Swift is a modern open-source programming language for iOS, OS X, tvOS, watchOS and Linux.
There is the official Swift blog from Apple which has updates and code snippets, however more recently there has been a lot of activity of the Swift@ IBM blog.
In particular Bring Swift to the Cloud and the IBM Swift Sandbox that allows you to write Swift code in a browser and then execute it. You can try it out here https://swiftlang.ng.bluemix.net/#/repl.
Introduced in 2014, Swift is one of the fastest growing and most widely used programming languages. In just over two months since Apple open sourced the Swift language and IBM released its Swift Sandbox for early exploration of server-side programming in Swift, more than 100,000 developers from around the world have used the IBM Swift Sandbox and more than half a million code runs have been executed in the Sandbox to date
