Description
I declare an enum with integer type and default value in my OpenAPI declaration. But while generating a swift4 client, the generate command fails with following error.

In toDefaultValue, Convert to String by toString if the schema is enum and not string type.
|
if (p.getEnum() != null && !p.getEnum().isEmpty()) { |
|
if (p.getDefault() != null) { |
|
return "." + escapeText((String) p.getDefault()); |
