CurlDSL

2019 © Weizhong Yang a.k.a zonble

CurlDSL converts cURL commands into URLRequest objects. The Swift package helps you to build HTTP clients in your iOS/macOS/tvOS easier, once you have a cURL command example for a Web API endpoint.

CurlDSL does not embed cURL library into your project. It is also not a Swift code generator, but it is a simple interpreter, it parses and interprets your cURL command at run time.

The project is inspired by cURL as DSL by Yoshiki Shibukawa.

CurlDSL supports only HTTP and HTTPS right now.

Requirement

  • Swift 5 or above
  • iOS 13 or above
  • macOS 10.15 or above
  • tvOS 13 or above

Installation

You can install the package via Swift Package Manager.

Usage

There is only one important object, CURL. You can just pass your cURL command to it. For example:

try CURL("curl -X GET https://httpbin.org/json")

You can use it to build URLRequest objects.

let request = try? CURL("curl -X GET https://httpbin.org/json").buildRequest()

Or jsut run the data task:

try CURL("https://httpbin.org/json").run { data, response, error in 
    /// Do what you like...
}

Supported Options

We do not support all of options of cURL. The supported options are as the following list.
