error occured after tableView.endUpdates() - ios

Question

I tried to put a breakpoint and I noticed that error occured after the tableView.endUpdates
Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'Invalid update: invalid
number of rows in section 0. The number of rows contained in an
existing section after the update (333) must be equal to the number of
rows contained in that section before the update (333), plus or minus
the number of rows inserted or deleted from that section (0 inserted,
235 deleted) and plus or minus the number of rows moved into or out of
that section (0 moved in, 0 moved out).'
