libc++abi: terminating due to uncaught exception of type NSException

(lldb) 


Solution:


In attribute inspector goto the last option.Then below that it had some yellow exclamatory symbol outlet connections are there.Remove those connections and run the app.It will works.
Because someView has an errored outlet connection
