The xcode 26.3 project fails to compile after updating
Hi, this is an assertion in the static linker. In cases like this, it automatically creates a snapshot of the invocation that would allow us to reproduce it locally. The path to it is mentioned here in:
ld snapshot written at /tmp/AIChatDoctor-2026-03-10-150254.ld-snapshot
Could you please file a feedback report with the snapshot attached, so that we can take a closer look?
