Decoding JSON Data in Swift: Part 1
Building a Weather Application With Swift 3
In the previous tutorial of this series, we fetched weather data from the Dark Sky API. Before we can feed the weather data to the user interface of the application, we need to pour it into model objects. Swift's strict type safety rules make this less trivial than it sounds.

We also discuss when to use which pattern and, more importantly, when to avoid a particular pattern.
