WebRTC revision

Current revision: M125

Installation

The library is published to Maven Central.

Add dependency to your common source set:

commonMain.dependencies {
  dependencies {
    implementation("com.shepeliev:webrtc-kmp:$webRtcKmpVersion")
  }
}

Running on iOS

On iOS, the WebRTC SDK is not linked as a transitive dependency, so you need to add it to your iOS project manually. This can be done using CocoaPods or SPM, depending on your project setup. Here is an example of how to link the WebRTC SDK using CocoaPods in build.gradle.kts:

kotlin {
  cocoapods {
    version = "1.0.0"
    summary = "Shared module"
    homepage = "not published"
    ios.deploymentTarget = "13.0"

    pod("WebRTC-SDK") { 
      version = "125.6422.05"
      moduleName = "WebRTC"
    }

    podfile = project.file("../iosApp/Podfile")

    framework {
      baseName = "shared"
      isStatic = true  
    }

    xcodeConfigurationToNativeBuildType["CUSTOM_DEBUG"] = NativeBuildType.DEBUG
    xcodeConfigurationToNativeBuildType["CUSTOM_RELEASE"] = NativeBuildType.RELEASE
  }

    iosX64()
    iosArm64()
    iosSimulatorArm64()
}

Also add the following to your Podfile in the target section:

use_frameworks!
pod 'shared', :path => '../shared'

Usage
