[Swift3] Wrong enum types generated when enum is of custom type

[davidpasztor]

Description

Swift enum types are incorrect using swagger-codegen when the type should be a custom class
codegen generates an enum of Strings instead of an enum of custom types
Code generated by codegen:

public enum SomeType: String { 
        case foo = "Foo"
        case bar = "Bar"
        case bee = "Bar"
    }

I have manually managed to fix the enum and this is the correct Swift enum with custom types, where Foo, Bar and Bee are all custom classes that inherit from the same class in which SomeType is declared.

public enum SomeType {
        case foo(Foo)
        case bar(Bar)
        case bee(Bee)
    }

The Java version of swagger-codegen has been fixed already and generates the following, correct code:

public enum SomeTypeEnum {
    @SerializedName("Foo")
    FOO("Foo"),
    
    @SerializedName("Bar")
    BAR("Bar"),
    
    @SerializedName("Bee")
    BEE("Bee");

    private String value;

    SomeTypeEnum(String value) {
      this.value = value;
    }

    @Override
    public String toString() {
      return String.valueOf(value);
    }
  }

Swagger-codegen version

2.2.2

Not sure I understand. In that spec snippet there are only enums with type string. Could you post part of a spec and then what you would expect to be generated?
