[OmarIthawi]

Describe the bug

Exception is thrown when finding productRef instead of fileRef.

BAF0D4CB2AD6AE14007AC334 /* FacebookLogin in Frameworks */ = {isa = PBXBuildFile; productRef = BAF0D4CA2AD6AE14007AC334 /* FacebookLogin */; };

Exception is thrown when trying to remove unrelated files:

System information

1. pbxproj version used: 4.1.0
2. python version used: 3.10.12
3. Xcode version used: I don't know, I use the version on https://github.com/openedx/openedx-app-ios/blob/b2539a6f0ee00a06879f3820d438430a4346363e/Core/Core.xcodeproj/project.pbxproj#L1-L8 and I have no XCode on my Linux machine

TBD: Add more details here

The file is added despite productRef exists somewhere else.

Screenshots
None.

Additional context
