Attempt #1
his post mentions two things I have no idea where they are, maybe that will help or maybe its mentioning features only available in the referenced outdated version of Unity? 1. choose in player setting under other settings : universal platform and IL2CPP 2. update all plugins as these need to support arm64

tried changing the ... thingy up in the top left...it's like a button that states [Unity iPhone > iPhone] as opposed to a simulator or "General Device".

ere @rathodjignesh1805 merely tells you to expand two things, which...not sure how that's helpful. I think we're missing a step on what to do with the expanded sections. https://answers.unity.com/questions/1336791/apple-mach-o-linker-ld-error-group.html

Summation
am stuck I have no idea what to do. Please help me. I'm so desperate! Where do I throw my money!? In all honesty, thank you for your time!
I get the following error message: 
I got in touch with a local gamer's group and they helped out. Looks like the answer was in the warning. I removed all of Unity's ads, built the game, and archiving in XCode worked. No Link-O-Whatever error. So, then while re-implementing all the ads, I found that there were two scripts requesting the IUnityAdsListener in the class initialization lists, yet I was only using one of those files. Got rid of the second, and bam! We're good to go. Hopefully that helps someone else in the future!
I'm back...it didn't work. Once I enable the Ads in the Services tab, I get the $$anonymous$$ach-O-Linker again.
Got it. Unity Editor > Cloud > Services > Enable Ads > Advanced > DISABLE plugins (if you have the Unity Ads 2.0 SDK package installed from the Asset Store).
