I recently wrote an article for MobiForge outlining the importance of Swift and the effect it has on the industry. I also took this opportunity to compare it with Objective-C. Here is the abstract of the article:
"Now that the dust has settled somewhat on Swift, the new language on the block for developing iOS and OSX applications, we take a look at its impact and improvements over its predecessor, Objective-C. Apple claims Swift to be a modern, safe, and powerful language for developing for iOS and OSX. Just how powerful is Swift compared to the venerable Objective-C? And how does it make developing applications easier and safer? In this article, I will walk you through some of the important features in Swift and how it improves on Objective-C. In a follow up article, I will show you how you can use Swift and Objective within the same project."
