This Swift module is the native part of a RPC communication bridge between your app and a webview javascript.
It is designed to work together with its javascript counterpart, nrkno/nativebridge.

Requirements

In addition to nrkno/nativebridge, nativebridge-ios relies on WKWebView and script message handlers to work.

Installation

nativebridge-ios is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'nativebridge-ios'

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Usage

All communication with the javascript is managed through the WebViewConnnection class.

Communication follows a protocol where messages are sent back and forth between the javascript and your code.
Messages have a topic, and some data.
The data must implement the Codable protocol.

Establishing the javscript connection

One must configure the WKWebView instance by adding a script message handler (WKScriptMessageHandler) that will listen to messages sent to ‘nativebridgeiOS’.

See the example project for details on how to do this.

Sending data

let data = SomeDataType()
webViewConnection.send(data: data, for: Topic.someTopic)

Adding topic handlers

In order to react on messages sent from the javascript, one must add handlers to the WebViewConnnection instance:

webViewConnection.addHandler(for Topic.someTopic, {
    (input: InputDataType, connection) in {
        let message = "Received incoming: '(input.inputMessage)'"
        let output = OutputData(outputMessage: message)
        connection.send(data: output, for: Topic.someTopic)
    }
})
