Every iOS app already runs natively on Intel. Adding an ARM co-processor to the Mac doesn't change that situation.

It's possible to compile iOS apps for x86 if you have the source, but this x86 version is not included in what's shipped to the app store.

For simple apps this is more or less true.

More complicated cases might not behave same.

For example, ARMv8 and x86 have different memory models. So execution won't be equivalent. You can have concurrency bugs in your code that only manifest on ARMv8.

I'm sure there are a lot of other examples of differences as well.
