I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

The missing symbol comes from the GoogleMobileAds SDK rather than a Firebase SDK.

"_OBJCCLASS$_JSContext", referenced from: in GoogleMobileAds[arm64]448

The JSContext symbol is defined in Apple's JavaScriptCore framework: https://developer.apple.com/documentation/javascriptcore/jscontext?language=objc

I would recommend trying to link the JavaScriptCore by going to your target's build settings > Frameworks, Libraries, and Embedded Content > + > search for JavaScriptCore` > select and add.
