Apple's new Swift programming language takes flight with Getty Images, American Airlines, LinkedIn, and Duolingo

Daniel Eran Dilger AppleInsider:

Apple's new Swift programming language has only been available for a few months, but iOS and OS X developers from American Airlines, Getty Images, LinkedIn and Duolingo are reporting favorable impressions - ranging from increased productivity to fewer bugs in their shipping apps - as interest in the new language rapidly accelerates.

Interesting read.

Although Swift is already paying off, I think it's also a good example of Apple investing in its future. Apple has always been this type of company - thinking ahead, embracing change, carefully and patiently laying the foundation for its future.
