WireGuard Integration Guide

This guide aims to simplify the process of integrating WireGuard into your iOS application. I've tried to make this complex procedure easy. This project contains only integration, I will add connection part soon.

Step 1: Create a New Project

Start by creating a new project in Xcode if you haven't already done so.

Step 2: Add Network Extension

1. Add a new target to your project by selecting File > New > Target....
2. Choose the Network Extension target type and click Next.
3. Name your Network Extension, e.g., network-extension, and then click Finish.
4. When prompted to activate the scheme for the network extension, select Cancel.

Step 3: External Build System Setup

1. Add another new target by selecting File > New > Target... again. We are using this external build system for building wireguard.

2. This time, select External Build System.

3. Name this target WireguardGoBridge.

4. In the Build Tool field, enter $(PROJECT_DIR)/script/build_wireguard_go_bridge.sh.

   • This script is responsible for building the WireGuard. You can find the script at script/build_wireguard_go_bridge.sh. Add script to your project.
   • Modify the Go path in the script at line 38 as necessary, according to your setup. Refer to this Stack Overflow answer for guidance.

Step 4: Add WireGuardKit Dependency

1. To your project, add the WireGuardKit dependency by navigating to Project > Package Dependencies, then click the + button.
2. Enter the URL https://git.zx2c4.com/wireguard-apple and select the exact version 1.0.15-26.
3. When prompted, select the network-extension target for the package.

Step 5: Configure Targets

1. For your Network Extension (NE) target:

   • Go to Build Phases > Target Dependencies and add WireguardGoBridge as a dependency.
   • Under Build Phases > Link Binary with Libraries, ensure WireguardKit and NetworkExtension.framework are available.

2. Ensure WireguardKit targets the network-extension in its build phases.

Step 6: Add Configuration Extensions

In your Network Extension target, add TunnelConfiguration+wgQuickConfig and String+ArrayConversion extensions. These will help in configuring the tunnel and handling array conversions, respectively.
