(Old) Code written on older Xcode vs M1 Xcode... issues/differences?

Sorry for the awkward title, I'm incredibly green regarding iOS development and even just Macs in general.

I have code for a working (and published) app that was written quite a while ago and I'm wondering if it should just compile without issues on M1 Xcode or if there would inherently be tweaks that need to be done, dependency issues, etc? I ask because it doesn't of course compile, but being green, I'm just unsure if my first issue is because I'm using an M1 MBP with Xcode 14 and there would be a ton of settings I need to tweak (such as Swift versions etc) or if the project's config files should "handle" telling Xcode how it should be compiled?

I have, seemingly, downloaded all of the dependencies in the pod but it does complain, specifically, about a TrueTime dependency not being available but again I'm just unsure if there are some changes that need to be made for a project that wasn't written with M1 in mind or not.

Issue is not M1 per se, but more the version of Xcode you were using at the time.

iOS API have probably changed, Swift syntax as well. ANd your Pod may not be up to date.

You should show the type of errors you get.
