get_openapi_schema outputs types using anyOf style - doesn't work with the Swift OpenAPI generator

[IanHoar]

Hey there,

I'm working with a client team that is using django-ninja to build their API. They have handed me a schema.json file that I've converted to yaml and I'm trying to import into my Swift project. When I generate the client side code using the Swift OpenAPI Generator I get errors on every instance where I see this syntax:

my_property:
  anyOf:
    - type: string
    - type: 'null'

Hand converting to this syntax throughout the entire spec allows the generation to succeed:

my_property:
  type: [string, 'null']

My question is this: Is there a way to have django-ninja output this updated type style? Any information to help me wrap my head around this issue would be helpful
