We commonly say that you should only use libraries that you thoroughly understand but we rarely take the time to really dig into those libraries to see how they work. How exactly does Alamofire use a URLRequest or a URL String to make a network call? It’s been a while since I wrote the previous tutorial. There are a few reasons for that but a big one is that I didn’t feel confident difficult. Often it just works but when it doesn’t you suddenly have to write a ton of not very obvious code, sometimes even to handle the With more experience, I’m finding better ways to avoid writing as much custom code, like making the types for individual properties Codable instead of writing custom code for the top-level Codable item in my JSON. Like any language feature, it has some pros and cons so I didn’t want to just say “it’s great, use it all the time”. Now that I’ve had a chance to use Codable for varying projects, I’m comfortable making recommendations and writing up examples. Today we’ll look at handling Codable items in Alamofire responses. Completion handlers can be a bit tough to wrap your head around when you first encounter them. Here are a few of the most frequently asked questions about completion handlers that I see from newer Swift developers. Swift 4 includes a new way to generate & parse JSON using the Codable protocol. It’ll get rid of some boilerplate, especially when the objects or structs in our code have a similar structure to the JSON that we use to talk to a web service. In many cases you’ll be able to avoid writing any code that explicitly parses or generates JSON, even if your Swift structs don’t exactly match the JSON structure. Codable can also replace use of NSCoding when we want to serialize objects to write them to a file and read them back again Today let’s look at the simple case of converting an object or struct in our code to & from JSON. Then we’ll see how it might be more complicated when the JSON doesn’t match the objects & structs that we’re using in our code. We’ll use structs below but
