Is there a neat way to work with deeply-nested JSON?

What you’re describing are “Data Transfer Objects”, or DTOs. It’s very common to have DTOs that match the data from your API, that are then used to manipulate the data into the objects you actually want to use on the client, so working with the messy or bad (or just full of unneeded) API data doesn’t infect your own client code. When you don’t control the data coming from the API, it’s an unfortunate necessity. I don’t have any experience with it, but apparently GraphQL is supposed to solve this, but not every API is going to offer it. You could manipulate the data in your decodable init, but then that gets to be pretty messy if you’re needing to do a lot of manipulation, and working with a DTO might end up being better anyways.

Complex JSON nesting of objects and arrays

The first code is an example of Javascript code, which is similar, however not JSON. JSON would not have 1) comments and 2) the var keyword

You don't have any comments in your JSON, but you should remove the var and start like this:

orders: {

The [{}] notation means "object in an array" and is not what you need everywhere. It is not an error, but it's too complicated for some purposes. AssociatedDrug should work well as an object:

"associatedDrug": {
                "name":"asprin",
                "dose":"",
                "strength":"500 mg"
          }

Also, the empty object labs should be filled with something.

Other than that, your code is okay. You can either paste it into javascript, or use the JSON.parse() method, or any other parsing method (please don't use eval)

Update 2 answered:

obj.problems[0].Diabetes[0].medications[0].medicationsClasses[0].className[0].associatedDrug[0].name

returns 'aspirin'. It is however better suited for foreaches everywhere

I successfully solved my problem. Here is my code:
