Building Steps

An iOS Cordova application including the cordova-plugin-iosrtc plugin can be built using the cordova-cli or Xcode.

The plugin provides a "hook" to automate required modifications in both cordova-cli and Xcode generated projects.

  • Put the hook script under the "hooks/" folder of your Cordova project (or wherever you prefer) and give it execution permission:
$ chmod +x hooks/iosrtc-swift-support.js
  • Add these lines to you "config.xml" file:
<platform name="ios">
	<hook type="after_platform_add" src="hooks/iosrtc-swift-support.js" />
  • Make sure you have the NPM xcode package installed (locally or globally):
$ npm install -g xcode
  • Remove the iOS platform and add it again:
$ cordova platform remove ios
$ cordova platform add ios
  • You have two options right now:
    • Open the Xcode project and compile your application.
    • Build the application as usual using the Cordova CLI:
$ cordova build ios

Bridging Header

The plugin is coded in Swift language but it makes use of the Cordova Objective-C headers and the Google's WebRTC Objective-C wrapper so a Bridging Header is required. When building (using the provided hook above) our Bridging Header file is automatically added into your Cordova project.

It may happen that your Cordova application uses more than a single plugin coded in Swift, each of them requiring its own Bridging Header file. Unfortunately just a single Bridging Header can be set in a Xcode project. The solution is to create a "Unified-Bridging-Header.h" file within your project and include all the Bridging Header files required by the plugins in there. For example:


// cordova-plugin-apple-watch "Apple Watch"
#import "Watch-Bridge.h"

// cordova-plugin-iosrtc
#import "cordova-plugin-iosrtc-Bridging-Header.h"

And then set Unified-Bridging-Header.h as the value of the "Objective-C Bridging Header" build setting in your Xcode project. For more information check this issue.


If you still prefer to do it manually open it with Xcode and follow these steps:

  • Set "iOS Deployment Target" to 7.0 or higher within your project settings.
  • Set "Deployment Target" to 7.0 or higher within the project target settings.
  • Within the project "Build Settings" add an entry to the "Runpath Search Paths" setting with value @executable_path/Frameworks.
  • Within the project "Build Settings" set "Objective-C Bridging Header" to PROJECT_NAME/Plugins/cordova-plugin-iosrtc/cordova-plugin-iosrtc-Bridging-Header.h (read more about the "Bridging Header" above).
  • Within the project "Build Settings" set "Enable Bitcode" to "No".

iOS 10 notes

On iOS 10 each permission requested must be accompanied by a description or the app will crash. Here is an example:

<platform name="ios">
    <config-file parent="NSCameraUsageDescription" target="*-Info.plist">
	<string>Blink uses your camera to make video calls.</string>
    <config-file parent="NSContactsUsageDescription" target="*-Info.plist">
	<string>Blink needs access to your contacts in order to be able to call them.</string>
    <config-file parent="NSMicrophoneUsageDescription" target="*-Info.plist">
	<string>Blink uses your microphone to make calls.</string>
