What Is Core Data
A common mistake developers new to Core Data make, is not taking the time to learn the basics of the framework. If you don't know what Core Data is, it is very hard to understand the ins and outs that make the framework tick.

Value Types And Reference Types In Swift
When talking about object-oriented programming, most of us intuitively think about classes. In Swift, however, things are a bit different. While you can continue to use classes, Swift has a few other tricks up its sleeve that can change the way you think about software development. This is probably the most important shift in mindset when working with Swift, especially if you are coming from a more traditional object-oriented programming language like Ruby or Objective-C.
