Swift model generate problem, if $ref in model, $ref is ignored.

"AdventuresQuery": {
        "allOf": [
          {
            "$ref": "#/components/schemas/EntitySearchQuery"
          },
          {
            "type": "object",
            "additionalProperties": false,
            "properties": {
              "all": {
                "type": "boolean"
              },
              "recommended": {
                "type": "boolean"
              },
              "fields": {
                "$ref": "#/components/schemas/AdventuresQueryFields"
              }
            }
          }
        ]
      },

In swift generator you get this code

public struct AdventuresQuery: Codable {

    public var all: Bool?
    public var recommended: Bool?
    public var fields: AdventuresQueryFields?

    public init(all: Bool? = nil, recommended: Bool? = nil, fields: AdventuresQueryFields? = nil) {
        self.all = all
        self.recommended = recommended
        self.fields = fields
    }


}

as you can see EntitySearchQuery is ignored.

Start by reproducing the Swift generator output with the provided AdventuresQuery schema, then trace the Swift model-generation path handling the allOf $ref to EntitySearchQuery. Done means the generated AdventuresQuery preserves the EntitySearchQuery fields or relationship instead of ignoring that reference.
