Setup in Unity for Xcode with Toolchains

I'm using iXGuard for my Unity Project and need to build on XCode with iXGuard Toolchains (Xcode menu -> Toolchains -> select iXGuard Toolchains, and also need to add a new script for Post Action (Product -> Scheme -> Edit Scheme -> Archive -> Post-actions )

The question is how can I setup/add in Unity to configure for it instead of manual configure on Xcode?
