Introduction

Are you over feeling the pain of manually updating your Swift models after finding out (the hard way) that your dependency's JSON schema changed?

swiftgen is a code generation tool for Swift that can help alleviate this pain point by automatically generating models based on a specified schema or structure. This can help ensure that your models are always up-to-date with the latest version of the API, and can save time and effort that would otherwise be spent manually updating models.

Building swiftgen

Prerequisites:

Go development kit of a supported version. Follow these instructions to prepare the environment.

To build and install it:

go install github.com/kevherro/swiftgen@latest

The binary will be installed in $GOPATH/bin ($HOME/go/bin by default).

Basic usage

swiftgen can read a JSON schema file and convert it to Swift structs.

Generate Swift code based on a JSON schema file

% swiftgen --src <json_schema_file> --dest <swift_file>
Where
    json_schema_file: Path to the JSON schema file. Required.
    swift_file: Path to the destination Swift file. Required.

swiftgen project structure is heavily influenced by pprof. Thanks y'all!
