Ios swift – Xcode error: grpc.framework is missing its bundle executable

I am pretty novice at coding and Xcode, so please forgive me if I’m asking a silly question or making a stupid error… I’ve tried to search online to resolve myself, but am just stuck at this point.

My iOS app (Swift and SwiftUI) has been going along smoothly as I’ve been building it, up until this morning. It was building and running in the simulator, and on devices just fine.

Then suddenly I’ve started receiving the error in the screenshot below, and I’m confused because I don’t think I’ve changed anything (at least not consciously).

I can’t find the exact same issue on Google, but it does seem like suggestions were to look in the build phases of the app target, which seems to show the following:

I am using Firebase (which is the only real package I manually added) which was installed using Xcode’s package dependencies manager (I see the there are obviously other dependencies which were installed because of Firebase, one of which is gRPC which I do see in the Package Dependencies section in the navigation pane) and as I say, all was working fine up until this morning. I’ve tried to re-add the Firebase but I don’t seem to be getting anywhere.

Unsure why this would run in simulator but suddenly stop on the device itself. Help would be greatly appreciated!
