Firebase Functions crashing app via TestFlight and XCode 26.4

Probably more of a public service announcement than something the Devs need to fix:

Firebase Functions crashes the app when it was installed via TestFlight and built/uploaded with XCode 26.4.

This cost me a good couple of hours today. The fix is simple: Side Install XCode 26.3 from the following link and build/publish through that:

Do you have any official source for this which we could link?

Yes I believe so:
