You've set up Xcode and wrote your first program, but you probably don't yet understand how the code you wrote works. That's OK, we'll get there! In this tutorial we'll learn about two of the basic building blocks of computer programs, constants and variables.
You've decided you want to learn programming. Maybe you have an idea for an app, maybe you're looking to change careers, or maybe you just think it's something you would enjoy doing. Whatever the reason, welcome!
In this tutorial, we'll look at a case study of using conditional conformance in unit tests. The problem we'll be solving is a common one. You have a set of stubbed JSON responses and you want to test that they are serialized correctly into Swift model types. Some responses return a single model resource while others return a collection.
In the last tutorial, we built a cross-platform Swift framework. If you want to reuse your frameworks in other projects, the next step is to support dependency managers. The three most popular right now are CocoaPods, Carthage, and Apple's Swift Package Manager.
With technologies like handoff and continuity, a unified developer program, and many of the same system frameworks available on all four of its platforms, Apple has been moving over the past few years to more seamlessly integrate its ecosystem of devices. This presents a great opportunity for us to bring our apps to each platform while reusing a lot of the app logic we've already written.
