same crash

I'm also facing this issue. In my case, I'm just reloading a cell like this:

DispatchQueue.main.async {
    self.tableView.beginUpdates()
    self.tableView.reloadRows(at: [IndexPath(row: 0, section: 0)], with: .none)
    self.tableView.endUpdates()
}

I'm doing this in the success case of an API call.

Is there a way to prevent this method swizzling from happening? I suspect it's somehow the cause of this crash.

Update:

This crash happened during App Store review and resulted in rejecting my app.

I really hope it is investigated and fixed sooner than later.

@alobaili you can always implement your own, or attempt to fix, or not use? Seriously.

@dzenbot I understand the risks. I just wanted to share my experience. Consider it feedback or bug report to help the creators investigate and improve.

Best,
