Why does an iOS app have to be code signed before it runs? Focus on what the signature guarantees from a security point of view.
Code signing lets the kernel check who built the app (identity) and that nothing changed afterward (integrity) before any code runs, which blocks tampered binaries and unapproved distribution.
