Can't load app with firebase onto my iPhone, Xcode 12, iOS 14

Question

As soon as I install Firebase in my project, my app can no longer load onto my iPhone 11 Pro. I get a popup that says ”Unable to install ‘app name’”. I have tried installing with SPM, Cocoapods, Carthage and manual installation. I don’t even have to call FirebaseApp.configure(), just its very presence triggers this.

I tried a brand new project that I built just to narrow down the problem. The deployment Info is for iOS 14.0 on iPhone and iPad

I am installing Firebase 7.11.1 in SPM, not sure what version I’m getting in the other methods. My iPhone is at iOS 14.5 and the compile is with Xcode 12.5 on an M1 MacMini with macOS 11.3.

I also tried it on a 2019 27” iMac running macOS 11.2.3, Xcode 12.4. I got the same results.

Is this just a Firebase problem? Or is there something else that I’m just not seeing?

The details of the failure are as follow:
