That's a big argument for SwiftUI, which replaces storyboards.
But if you must use them, keep each storyboard small enough it's only going to be used by one dev at a time to avoid conflicts, and then combine trusting the GUI won't make stupid XML plus some automated UI tests to make sure functionality isn't damaged by e.g. a button being deleted.
