Before, when we could check:

Code Block swiftlet isRunningTests = NSClassFromString("XCTestCase") != nil

And then load a "testing AppDelegate" instead of the app's one on main.swift, so you could avoid making extra configurations that just add overhead when running unit tests.

I think it's not possible to have 2 @main structs, how should we achieve this now?

Thank you.

You could use an environment variable. Edit your scheme and add an environment variable for testing e.g. isTesting = YES. In your app you can read from it using ProcessInfo.processInfo.environment["isTesting"] and perform your configuration based on the result.
