Setup

1. Open NetGuardPro.xcodeproj in Xcode 15+.
2. Set your development team on both the NetGuardPro and NetGuardVPN targets.
3. Ensure the Network Extension capability is enabled in your Apple Developer portal for the bundle IDs com.netguardpro.mobile and com.netguardpro.mobile.vpn.
4. Create an App Group group.com.netguardpro.mobile in the portal and enable it on both targets.
5. Build and run on a physical device (Network Extension does not work in the Simulator).
