SwiftyURLProtocol is an URLProtocol wrapper. Can be used in conjunction with UIWebView to provide http/sock proxy support.

Features

• Multiple proxies
• Router to define which proxy to use for a request
• fixes SOCKS proxy bug on iOS (hosts are resolved locally instead of via proxy)

Requirements

• iOS 10.0+ / macOS 10.12+
• Xcode 8.1+
• Swift 3.0+

Installation

Include SwiftyURLProtocol as an framework into your project.

Usage

URLSession

To use SwiftyURLProtocol with URLSession add it into URLSessionConfiguration.protocolClasses

import SwiftyURLProtocol

SwiftyURLProtocol.setRouter { (request) -> ProxyURLProtocol.Proxy? in
    return ProxyURLProtocol.Proxy.socks(host: "127.0.0.1", port: 9050, probe: nil)
}

let config = URLSessionConfiguration.default
config.protocolClasses = [SwiftyURLProtocol.self]

let task = session.dataTask(with: URL(string: "http://google.com")!) { (data, response, error) in
    ...
}
        
task.resume()

UIWebView

URLProtocol.registerClass(ProxyURLProtocol.self)

To use SwiftyURLProtocol with UIWebView register it in URLProtocol

import SwiftyURLProtocol

// route all .onion hosts via socks proxy. Everything else will be accessed directly.
SwiftyURLProtocol.setRouter { (request) -> ProxyURLProtocol.Proxy? in
    if request.url?.host?.hasSuffix(".onion") ?? false {
        return ProxyURLProtocol.Proxy.socks(host: "127.0.0.1", port: 9050, probe: nil)
    }
    else {
        return nil
    }
}

URLProtocol.registerClass(SwiftyURLProtocol.self)
