Problem

We're using datamodel-code-generator for our Python code at @airbytehq, and I was about to make a little experimental app with Swift on our protocol, and realized there is not great way to generate models in Swift for JSON Schemas.

Let's add Swift support!

Solution

A good solution should:

• Generate Swift Structs for each model
• Structs should conform to Codable
• Structs should retain relations
• Structs should validate primary keys and foreign keys
• Structs should validate data types and other constraints described in JSON Schemas and specs.
• Structs must not use CoreData or SwiftData or other Apple-specific frameworks. Cool to add support, but consider that a separate output format. I don't want to lock-in to Apple frameworks. Swift on Server and all that.

Additionally, generated code should be validated:

• Run swift-format on the generated code if available
• Run swift build on the generated code (that might require making a dummy package / library target).

Great, who wants to build that?

I would be interested in tinkering with this. Before starting, wanted to run this by @koxudaxi to see if it makes sense to add Swift generation to koxudaxi.
