[Swift3] [Swift4] Fails to create array of strings, integers, floats, etc...

[ornithocoder]

My swagger.json file has something like this to define an array of doubles:

    "arrayOfDoubles": {
      "type": "array",
      "items": {
        "type": "number",
        "format": "double"
      }
    },

But swagger-codegen creates the following typealias for the array, without the type (which fails to compile):

public typealias ArrayOfDoubles = []

I'm using 2.2.3.

Updates:

• Same result with 2.3.0.
• Same result using Swift4.

To make our life easier, can you pls share the full spec and a minimal spec to repeat the problem?

[ornithocoder]

Sure. This is a fake one but reproduces the problem:

$ cat prices.swagger.json

        },

        ],

    }

      }
    },
    "suggestResponse": {
      "type": "object",
      "properties": {
        "results": {
          "type": "array",
          "items": {
            "$ref": "#/definitions/suggestResult"
          }
        }
      }
    },
    "suggestResult": {
      "type": "object",
      "properties": {
        "title": {
          "type": "string"
        },
        "prices": {
          "$ref": "#/definitions/suggestPrices"
        }
      }
    }
  }
}

$ cat prices.swift.config
{
  "projectName": "PricesClient",
  "podVersion": "0.0.1",

  "podAuthors": "Lord Vader",
  "podSource": "{ :git => 'git@github.com:swagger-api/swagger-codegen.git', :tag => s.version.to_s  }"
}

swagger-codegen generate \
    -i prices.swagger.json \
    -l "swift3" \
    -c prices.swift.config \
    -o "./"

Thanks :-)
