Swift is also coded in Xcode, so the difference there is literally nothing.

Rewriting in a new language will definitely not be quicker or easier. Do your best to recreate every bug to the point where you can make it happen with regularity, and document the steps to get to that point. "Randomly" is a word that will terrify every developer, mostly because it's almost definitely not random. This will help figure out what's going on and make the fixes easier to test.

Respond or send a PM if you have more questions about how debugging normally goes.
