If you search the ’net for “Unsupported Swift Architecture”, you’ll find a bunch of helpful advice on this front. My additions to that are:

If you’re using third-party tooling or libraries, seek help from the support channel for the relevant vendor.

If you get stuck, try to isolate the problem into a small test project and then share that here.
