Vonage Video iOS SDK (also known as Opentok iOS SDK) is available only via Cocoapods. This article explains how to convert this SDK into a SPM package. This is a workaround until an official SPM package is released by Vonage. This script works only for Opentok iOS SDK version 2.24.0 onwards.

Objective

Convert Opentok SDK on IOS to into an SPM package

Applies To

• iOS Client SDK

Procedure

1. Download the Opentok XCFramework package from Cocoapods.
2. Extract the Pods/OTXCFramework/OpenTok.xcframework and Pods/VonageWebRTC/VonageWebRTC.xcframework to a new folder Opentok-SPM-x.y.z
3. Create a Package.swift file in the Opentok-SPM-x.y.z folder describing the package.
4. Create a local git repo, commit and add a tag.
5. Use the full path to the Opentok-SPM-x.y.z folder as the package path in Xcode and install it.

The BASH script below performs the above tasks 1-4.

Execute the script as show below to generate SPM package for Opentok SDK 2.24.1

$ ./generateSPM.sh 2.24.2
