[Swift3] Array of string appears broken

Description

Hi guys,
Arrays of strings appear broken in the swift 3 client. Using the swagger declaration below, it generates the following file:

public typealias UserInstruments = []

When it should be

public typealias UserInstruments = [String]

And in the Decoders:

        // Decoder for UserInstruments
        Decoders.addDecoder(clazz: UserInstruments.self) { (source: AnyObject, instance: AnyObject?) -> UserInstruments in
            let sourceArray = source as! [AnyObject]
            return sourceArray.map({ Decoders.decode(clazz: .self, source: $0, instance: nil) })
        }

When it should be:

        // Decoder for UserInstruments
        Decoders.addDecoder(clazz: UserInstruments.self) { (source: AnyObject, instance: AnyObject?) -> UserInstruments in
            let sourceArray = source as! [AnyObject]
            return sourceArray.map({ Decoders.decode(clazz: String.self, source: $0, instance: nil) })
        }

Still trying to spot the problem, but if someone that actually coded the client could have a look I would greatly appreciate it!

Thanks!

Swagger-codegen version

2.2.3

Swagger declaration file content or url

  UserInstruments:
    type: array
    description: |
      An array of the instrument identifiers that the user plays.
    items:
      type: string
      pattern: ^[a-z]+\.[a-z-]+$
    example:
    - keyboards.grand-piano
    - brass.trumpet
    - strings.violin

Command line used for generation

swagger-codegen generate -i https://url.com -l swift3 -o ../api-client-swift3 -c conf.json

Reproduce the issue with the shown Swagger declaration and the swift3 generation command. Inspect the Swift3 generator templates responsible for the array typealias and decoder, and consider the issue done when string arrays generate [String] and decode with String.self.
