NSRangeException beyond bounds when inserting row into a tableview off screen iOS

Question

I'm having a problem with my Swift/iOS app when it comes to dealing with a UITableView using static cells.

My tableview has a couple of sections in it, which in turn each section has a couple of rows in it. In my code, if you tap on one of the cells, it will dynamically insert another cell into the table. For example, tapping on a row for date, will insert a data picker in a new cell, thus pushing the other row down the screen further.

On devices with larger screens this works just fine. The table row gets inserted and everything works fine because even with the data picker inserted, all the rows still fit on the screen. However, on a device with a smaller screen, if the inserted row pushes any of the rows below if off screen, and I try to scroll down to those rows, I get an NSRangeException, beyond bounds. I can't seem to figure out how to handle telling the tableview that those rows do exist and allow me to scroll without crashing.

I can supply more information if this isn't enough.

Thanks!

And finally, here is the error I'm getting.
