Integrating our apps with HTTP APIs often involves a fair amount of 'busy work'. Writing models to match API responses, manually iterating each field in a JSON object, and typing each in as a Swift property can be a bummer. Today we'll check out a great new tool from Josh Smith called json2swift that can help us here. It can generate Swift model code from a JSON object. Let's give it a try.
After we've installed json2swift, we can run it like this:

Json2swift: Generate Swift Data Models Based on JSON Data by Josh Smith. What sets this JSON-to-Swift converter apart from the others is its type inference capabilities. The net result is Swift code that uses the most appropriate data types possible. This functionality really shines when analyzing an array of elements.
Josh Smith with a new command line tool which takes a JSON file and spits out a Swift 3 model class. It's probably not something you'll use every day, but it'll save you plenty of time on the occasions that you do need it! Quicktype infers types from JSON sample data, then outputs Swift structs and converters (Go, C#, TypeScript and other output languages are supported). We were inspired by tools like json2swift, Cute Baby etc. That try to do the same thing, but we are taking a more rigorous approach, and so far we handle maps, struct unification, naming, top-level arrays, reserved words, convenience.
This will create a new file called Spaceship.swift in the same directory as our .json.
This means if our Spaceship.json file looked like this:
The resulting json2swift-generated Swift model would look like this:
Neat!
json2swift has generated an immutable Swift struct from our JSON file. Pro Tip: We can also run this on a directory full of JSON files, and it will process all of them.
json2swift will even try to determine which properties should be optional, and which are required. It will then generate the appropriate init code.
We're even provided some special handling for things like Date parsing. If we put a special String like this in our original JSON:
This will give us a: A good personal daily planning app for mac.
property, as well as generate the appropriate Date format/parsing code needed to make it work. Neat!

We've only scratched the surface, json2swift has great support for intelligenty inferring types for things like numbers, and even URLs. Learn more about json2swift at git.io/json2swift.
