As getluky states in his answer on Unity Answers:

I’ve seen SIGBUS often occur on NULL reference exceptions that occur
at runtime. They are usually fairly straightforward to track down via
the XCode debugger – hit the Continue button a couple times while
monitoring the XCode debug console output. It usually will give a hint
as to what file and line number the null reference was in.

Not sure why recreating the XCode project would fix it – it’s usually
an issue that recurs unless I can fix the underlying problem
