[Swift4] Model initializer with required properties only

To illustrate my problem I'm going to use the Client model available below. In our Client model, there are 26 properties, where only 3 are required (non-optional).

Client.swift.zip

In swagger-codegen-2.4.0 models are generated with no initializers, when a model has only optional properties, I'm able to initialize it with no arguments (so Client() is possible), however, when there's at least one required property the only initalizer available forces me to pass values to the required arguments and nil to the rest, as follows:

let client = Client(cpf: clientCPF, name: clientName, email: clientEmail, alternateEmail: nil, motherName: nil, birthDate: nil, maritalStatus: nil, maritalPartner: nil, identityDocuments: nil, personalPhones: nil, residentialAddress: nil, professionalData: nil, birthCity: nil, birthState: nil, graduation: nil, fatherName: nil, nationality: nil, residenceType: nil, gender: nil, clientReferences: nil, clientAssets: nil, residenceLiveYears: nil, consultCreditDataAuthorization: nil, proxy: nil, paymentOption: nil, debitAccount: nil)

I'd like to have an initializer with only required properties, like:

let client = Client(cpf: clientCPF, name: clientName, email: clientEmail)

Being forced to pass nil to all optional properties when initializing a model when I only need a couple of properties looks really bad.

Is it possible to have another initializer that takes only required properties?

swagger-codegen-2.4.0

java -jar ~/Documents/projects/swagger/swagger-codegen-2.4.0/modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -i /Users/me/Downloads/swagger.json -l swift4 -o /Users/me/Downloads/swagger-output

Start by locating the swift4 generator template used by the shown swagger-codegen CLI command and inspect how the generated Client.swift initializer is formed. Generate a model containing both required and optional properties, then verify that the output supports initialization with required properties only while preserving the existing behavior for optional properties.
