Overview

SwagGen

SwagGen is a library and command line tool for parsing and generating code for OpenAPI/Swagger 3.0 specs, completely written in Swift.

Swagger 2 support has been removed. For Swagger 2 use version 3.0.2 or the swagger_2 branch

Swagger parser

It contains a Swagger library that can be used in Swift to load and parse Swagger specs.

Swagger code generator

SwagGen is command line tool that generates code from a OpenAPI/Swagger 3.0 spec. Templates for any language can be written that leverage this generator.

It is an alternative the official swagger-codegen java code generator, and adds some improvements such as speed, configurability, simplicity, extensibility, and an improved templating language.

Swift template

SwagGen includes a bundled template for generating a client side Swift library for interfacing with the Swagger spec. It includes support for model inheritance, shared enums, discrete and mutable request objects, inline schemas, Codable and Equatable models, configurable options, generic networking stack, and many other niceties.

Installing

Make sure Xcode 11+ is installed first.

Mint

$ mint install yonaskolb/SwagGen

Homebrew

$ brew tap yonaskolb/SwagGen https://github.com/yonaskolb/SwagGen.git
$ brew install SwagGen

Make

$ git clone https://github.com/yonaskolb/SwagGen.git
$ cd SwagGen
$ make install

Swift Package Manager

Use as CLI

$ git clone https://github.com/yonaskolb/SwagGen.git
$ cd swaggen
$ swift run

Use as dependency

Add the following to your Package.swift file's dependencies:

.package(url: "https://github.com/yonaskolb/SwagGen.git", from: "4.4.0"),

And then import wherever needed:

import SwagGenKit
import Swagger

Usage

Use --help to see usage information

swaggen --help
Usage: swaggen <command> [options]

Commands:
  generate        Generates a template from a Swagger spec
  help            Prints this help information
  version         Prints the current version of this app

generate

swaggen generate path_to_spec

Use swaggen generate --help to see the list of generation options.

spec: This is the path to the Swagger spec and is a required parameter. It can either be a file path or a web url to a YAML or JSON file
--language: The language to generate a template for. This defaults to swift for now.
--template:: This is the path to the template config yaml file. It can either be a direct path to the file, or a path to the parent directory which will by default look for /template.yml. If this is not passed, the default template for the language will be used.
--destination: The directory that the generated files will be added to.
--option: An option that will be merged with the template config options with those in this argument taking precedence, meaning any existing options of the same name will be overwritten. This argument can be repeated to pass in multiple options. Options must specify the option name and option value separated by a colon, with any spaces contained in quotes. Nested options in dictionaries can be set by using a dot syntax. The following formats are allowed:
- -- option myOption:myValue
- -- option modelSuffix: Model
- -- option propertyNames.identifier: id
- -- option "myOption: my value"
--clean: Controls if and how the destination directory is cleaned of non generated files. Options are:
- none: no files are removed (default)
- all: all other files are removed
- leave.files: all files and directories except those that start with . in the destination directory are removed. This is useful for keeping configuration files and directories such as .git around, while still making sure that items removed from the spec are removed from the generated API.
--verbose: Show more verbose output
--silent: Silences any standard output. Errors will still be shown

Example:

swaggen generate http://myapi.com/spec --template Templates/Swift  --destination generated --option name:MyAPI --option "customProperty: custom value --clean leave.files"

For the Swift template, a handy option is name, which changes the name of the generated framework from the default of API. This can be set in the template or by passing in --option name:MyCoolAPI.

Swift Template

List of all available options:

name	action	expected values	default value
name	name of the API	`String`	API
authors	authors in podspec	`String`	Yonas Kolb
baseURL	baseURL in APIClient	`String`	first scheme, host, and base path of spec
fixedWidthIntegers	whether to use types like Int32 and Int64	`Bool`	false
homepage	homepage in podspec	`String`	https://github.com/yonaskolb/SwagGen
modelPrefix	model by adding a prefix and model file name	`String`	null
modelSuffix	model by adding a suffix and model file name	`String`	null
mutableModels	whether model properties are mutable	`Bool`	true
modelType	whether each model is a `struct` or `class`	`String`	class
modelInheritance	whether models use inheritance. Must be false for structs	Bool	true
modelNames	override model names	`[String: String]`	[:]
modelProtocol	customize protocol name that all models conform to	`String`	APIModel
enumNames	override enum names	`[String: String]`	[:]
enumUndecodableCase	whether to add undecodable case to enums	`Bool`	false
propertyNames	override property names	`[String: String]`	[:]
safeArrayDecoding	filter out invalid items in array instead of throwing	`Bool`	false
safeOptionalDecoding	set invalid optionals to nil instead of throwing	`Bool`	false
tagPrefix	prefix for all tags	`String`	null
tagSuffix	suffix for all tags	`String`	null
codableResponses	constrains all responses to be `Codable`	`Bool`	false
anyType	override `Any` with custom type	`String`	`Any`
numberType	override default number type when format not specified	`String`	`Double`

If writing your own Swift template there are a few types that are generated that you will need to provide typealias's for:

ID: The UUID format. Usually UUID or String
File: The file format. Usually URL, Data or a custom type with a mimeType and fileName
DateTime: The date-time format. Usually Date
DateDay: The date format. Usually Date or a custom type.

Editing

$ git clone https://github.com/yonaskolb/SwagGen.git
$ cd SwagGen
$ swift package generate-xcodeproj

This use Swift Project Manager to create an xcodeproj file that you can open, edit and run in Xcode, which makes editing any code easier.

If you want to pass any required arguments when running in XCode, you can edit the scheme to include launch arguments.

Templates

Templates are made up of a template config file, a bunch of Stencil files, and other files that will be copied over during generation

Template config

This is the configuration and manifest file for the template in YAML or JSON format. It can contain:

formatter: Optional formatter to use. This affects what properties are available in the templates and how they are formatted e.g. Swift
templateFiles: a list of template files. These can each have their paths, contents and destination directories modified through Stencil tags. One template file can also output to multiple files if they path is changed depending on a list context. Each file contains:
- path: relative path to the template config. The extension is usually .stencil or the type it is going to end up as
- context: optional context within the spec. This is provided to the generated file, otherwise the full context will be passed. If this is a list then a file will be created for each object and the context within that list is used. (e.g. a file for every model in the spec definitions gets it's own definition context). Note that properties in the template options field can be used here
- destination: optional destination path. This can contain stencil tags whose context is that from the context above. e.g. if context was definitions then the path could be Models/{{ type }}.swift and the filename would be the type of the definition. If this is left out the destination will be the same as the path, relative to the final destination directory. If it resolves to an empty string it will be skipped and not generated.
copiedFiles: this is an array of relative paths that will be copied to the destination. They can be files or directories. This is used for files that won't have their contents, filenames or paths changed.
options: these are the options passed into every stencil file and can be used to customize the template. These options are merged with the options argument, with the argument options taking precendance. These options can be references in template file paths and their contents.

An example template for Swift can be found here

Template Files

These files follow the Stencil file format outlined here https://stencil.fuller.li

Formatters

Formatters change what information is available to the templates and how it's formatted. They can be specified via the formatter property in the template config. Usually these would map to a specific target language, but can be customized for different purposes.

Output Languages

SwagGen can be used to generate code for any language. At the moment there is only a formatter and template for Swift

Swift API usage

Usage documentation can be found in the Readme that is generated with your template.

Compile Errors in project

I was using Swagger codegen until recently. I had encountered error. I tried to generate files from SwagGen. I downloaded the repo project and created xcodeproj using this command in terminal "swift package generate-xcodeproj". I opened the project but i had some compile time errors in Sources/SwagGenKit/Utilities.swift

"/Users/next/Downloads/SwagGen-master/Sources/SwagGenKit/Utilities.swift:11:32: Same-type requirement makes generic parameter 'Key' non-generic"

Did i do something wrong in the installation process? I created a script file in folder and tried to run the script file but i got "Swag: command not found". Please guide me

[Bug] oneOf without encapsulated schema generates noncompilable code

Consider such structure:

  /path:
    get:
      summary: Some summary
      security:
        - APIAccess: []
      operationId: pathRequest
      parameters: []
      responses:
        '200':
          description: Some response
          content:
              application/json:
                  schema:
                      oneOf:
                          - $ref: "#/components/schemas/Message"
                          - $ref: "#/components/schemas/Status"

So, response with 200 code can be either Message or Status schema. Such structure results in this code:


extension API {
    /** Some summary */
    public enum PathRequest {
    ...
        public enum Response: APIResponseValue, CustomStringConvertible, CustomDebugStringConvertible {
            public typealias SuccessType = Status200

            /** Some response */
            case status200(Status200)

            public var success: Status200? {
                switch self {
                case .status200(let response): return response
                }
            }
...
        }
    }
}

Which results in compile error Cannot find type 'Status200' in scope – that's true it was not defined.

I solved this problem by encapsulating oneOf inside custom schema:

schemas:
    Entity:
        oneOf:
            - $ref: "#/components/schemas/Message"
            - $ref: "#/components/schemas/Status"

However, I spent some time figuring out how to overcome this bug. I expected framework to automatically generating such schema.

Getting `Reference ... is unresolved` when generating from OAS3

Hi,

I was wondering if OAS3 was supported and gave it a go.

I used code from master, passed this spec as a launch argument. Getting Thread 1: Fatal error: Reference #/components/schemas/User is unresolved

Not sure if it's a bug or something isn't supported yet.

[Question] Group API Endpoints by tags

Hi, first of all, thanks for your great work.

I'm working on creating RxSwift + Moya Swift template for Swagger. It worked perfectly after some modifications in Swift3 Codegen. I can finally make a PR but it is painful with inconsistent Java coding conventions, complex codebase.

Luckily, I found your awesome library while finalizing my code before making a PR (after nearly 2 months pending). I can easily understand your codes and implementing task #8. I will submit a PR after I finished.

But I have a question: It is possible to groups API Endpoints by their tags then put them in one file for example: Fake.swift, Pet.swift, Store.swift, User.swift? I see your suggestion in #5 but couldn't find a solution for my case.

Unused public struct Options

I have generated the code for my Swagger... In the generated code there are struct Options are generated for header field

that option are nowhere being set in the header anywhere.

to initialise the request those value in option are required which is not being set in header field.

Also i think those value should not be required in creating request

My swagger yml is at http://relatr-dev.westeurope.cloudapp.azure.com:8080/swagger/

You can refer the Signup request in which languageCode: and appVersion are required parameters for creating requesting but those are header parameters

Make Swaggen library work on Linux and split Model/Request/Client
Sorry it's a big PR 🙇‍♂️

This PR make swagger library work on Linux(with FoundationNetworking when needed) and still work on Darwin.

I did these changes because I needed to have a generated library working on Linux and Alamofire even the version 5 don't support Linux(https://github.com/Alamofire/Alamofire/pull/3098).

This PR will give more control on which part of generated code you want to use:

only Models (no need for Alamofire)

Models + Requests (no need for Alamofire / you can create a simple client if needed on Linux for example)

Models + Request + Client (required Alamofire)

The generated code is usable with or without dynamic library(it will now work with dynamic dependencies in Xcodegen that are imported in multiples frameworks).

This should change nothing at all to most people except the removal of Timeline(which is a class of Alamofire that have bleed into the client).

This should simplify refactoring of any part of the template if needed. For example if we want to migrate out of Alamofire it easier because now there is only one part of the code to focus on to remove it.

I did move code around lot and made multiple SPM targets but tried to reduce the other modifications to the strict minimum.

├── Client │ ├── APIClient.swift │ └── RequestBehaviour.swift ├── Models │ ├── APIModel.swift │ ├── AnyCodable.swift │ ├── Coding.swift │ ├── Enum.swift │ └── Model.swift ├── Requests │ ├── API.swift │ ├── APIRequest.swift │ ├── APIResponse.swift │ ├── APIService.swift │ ├── AnyRequest.swift │ └── Request.swift └── SharedCode ├── APIClientError.swift └── APIResult.swift

Issue

This force me to remove Timeline feature of Alamofire.

I'm not sure of what should be public in KeyedDecodingContainer if I can have guidance on that @yonaskolb ?

Support `discriminator` property is on the model

OpenAPI 3 supports specifying the discriminator on either the model or response objects. Currently SwagGen only works when the discriminator is on the response. When it's on the model, inheritance doesn't work properly, all objects (for example, when parsing an array of objects), are of the base class, not the proper subclasses.

SwagGen doesn't process the media type application/json;charset=UTF8

We have an OpenAPI v3 JSON that has media types of application/json;charset=UTF8. These are ignored by SwagGen when processing request bodies as it's explicitly looking for application/json or variations thereof with *.

I don't know how valid it is that this additional charset is being specified, the RFC for media types (https://datatracker.ietf.org/doc/html/rfc6838) talks about it in relation to text types only, but it's what we're working with in our automatically generated spec.

Issue with decoding when element is nullable array

If you take the following array:

[ {"id": 1, "name" : "test", "tags" : ["tag1", "tag2"]}, {"id":2, "name":"test2", "tags":null}]

it fails on decode with the error: Expected to decode Array but found a null value instead.

the "tags" element is correctly defined in the model as [String]? and the swagger document shows it is nullable.

It its possible to get around this by using the SafeOptionalDecoding:true option, but I would not have expected that to be required.

The spec yaml files in this repo fail lots of Swagger validations

Description

If we pass /Specs/PetstoreTest/spec.yml through the online validator a https://editor.swagger.io, it throws these validation errors:

Same goes for /Specs/Rocket/spec.yml (there're tens of errors on this one, they wouldn't all fit in a single screenshot):

And /Specs/TBX/spec.json:

And /Specs/TestSpec/spec.yml:

And /Specs/TFL/spec.json:

Room for Improvement

I think a great improvement would be to have a spec validation step in CI for this repo, so that on every PR we'd be checking if all the spec yaml files continue to be valid. Here's a reference: https://swagger.io/blog/api-design/validate-openapi-definitions-swagger-editor/

segmentation fault when attempting to generate from spec that contains `allOf` groups
Hey 👋

I've recently spent some time fighting with SwagGen because it would enter a recursion when attempting to parse a given json spec.

After much debugging, I narrowed down the problem to the presence of allOf groups in my spec.

I read a few issues and PRs in this repo, did some shallow code review in key parts of the code base to try to understand what problem the presence allOf was causing, that was triggering the recursion. Some of the issues/PRs: #221, #286, #267, #269, #217, #278. I couldn't figure out why it's crashing (entering a recursion) on my specific spec file 😬 Specially because the sample specs present in this repo do feature allOf groups, so I don't know what specific configuration in my spec files is causing this particular problem 😞

I tested with v4.3.1, v4.4.0, and v4.6.0, all of which caused the same problem (segmentation fault - a recursion somewhere).

If it helps at all, here's the stack trace (click to expand):

Line 0|Line 1|Line 2|Line 3|Line 4 --|--|--|--|-- ||||

Workaround

As a workaround for my specific case, since all of the allOf occurrences had a single element in the array, I replaced extracted its $ref out of the allOf key, directly in the JSON file, before parsing it using SwagGen. In Ruby, here's the script that worked for me:

# Taken from https://stackoverflow.com/a/4174125/4075379 def regex_replace_file(filename, regexp, replacement) require 'tempfile' Tempfile.open(".#{File.basename(filename)}", File.dirname(filename)) do |tempfile| File.open(filename).each do |line| tempfile.puts(line.gsub(regexp, replacement)) end tempfile.close FileUtils.mv(tempfile.path, filename) end end swagger_spec_path = "/path/to/your/spec.json" regexp = /"allOf":\[\{("\$ref":"#\/components\/schemas\/[a-zA-Z]+")\}\]/m regex_replace_file(swagger_spec_path, regexp, '\1') # swagger_spec_path now contains the processed JSON file, ready to be consumed by SwagGen

This workaround is admittedly terrible, but in my specific use case it didn't break anything. Use with caution.

"description" aka doc comments don't get generated nicely
Hey 👋

I've found an issue where code like this:

/** * This is a multiline * comment. */ public myProperty: MyClass[];

Gets translated into this swagger json:

… "myProperty": { "description": "* This is a multiline\n\t * comment.", "items": { "$ref": "#/components/schemas/MyClass" }, "type": "array" }, …

Which SwagGen (understandably) generates this:

// * This is a multiline * comment. public var myProperty: [MyClass]

Although swagger could do a bit better with providing a better generated "description" (e.g. not including the * characters), I think SwagGen should at least provide code that compiles, e.g.:

/// * This is a multiline /// * comment. public var myProperty: [MyClass]

In other words: using the dedicated doc comment syntax (///) and adding that delimited to the start of the line so that it's recognized as a doc comment (which makes the code compile).

Has this been considered? Or is there a better way to annotate doc comments in javascript? All the help is highly appreciated 🙏 Thanks!

APIClient.makeRequest now returns an Alamofire Request if one was created, so requests can now be cancelled

All operation responses are now generated, not just the successful one, meaning you get access to typed errors

Template Changes

Model

Properties in a model subclass initialiser will now be ordered so that all required properties come first, instead of parent and then child's properties

Now provides a CustomDebugStringConvertible conformance that pretty prints all nested values

APIRequest

Each APIRequest now has a typed Response enum that includes all it's responses in the spec. Each case has the decoded schema as an associated enum if specified

APIClient

The APIClient.makeRequest complete closure parameter has changed from DataResponse to APIResponse which:

replaces result value with the new response enum

has result error of APIError enum via antitypical/Result which has cases for:

unexpectedStatusCode(statusCode: Int, data: Data)

jsonDeserializationError(JSONUtilsError)

decodingError(DecodingError)

invalidBaseURL(String)

authorizationError(AuthorizationError)

networkError(Error)

unknownError(Error)

0.2(May 3, 2017)
Added

Operation, Definition, Property and Parameter, now have a raw property that can be accessed from templates. This represents the raw data that was in the original spec. This lets you access any custom properties you have in your spec
