Description

Swift4Codegen.java does not have type mapping for bigdecimal. Even if we add the below line

typeMapping.put("bigdecimal", "Double");

in Swift4Codegen.java and compile the jar and run it. it gives the below error

[main] WARN io.swagger.util.PropertyDeserializer - no property from bigdecimal, null, {ENUM=null, TITLE=null, DESCRIPTION=null, DEFAULT=null, PATTERN=null, DESCRIMINATOR=null, MIN_ITEMS=null, MAX_ITEMS=null, MIN_PROPERTIES=null, MAX_PROPERTIES=null, MIN_LENGTH=null, MAX_LENGTH=null, MINIMUM=null, MAXIMUM=null, EXCLUSIVE_MINIMUM=null, EXCLUSIVE_MAXIMUM=null, UNIQUE_ITEMS=null, EXAMPLE=null, TYPE=bigdecimal, FORMAT=null, READ_ONLY=null, VENDOR_EXTENSIONS={}, MULTIPLE_OF=null}

if I change my yaml and convert the
definitions:
User:
type: "object"
properties:
desk:
type: "number"
firstName:
type: "string"

then it works fine.
please tell me if 'number' should be used for big decimal in yaml? so that it gets converted to Double in swift?
