scrollToRowAtIndexPath throwing error

UITableView _contentOffsetForScrollingToRowAtIndexPath:atScrollPosition:]: section (3) beyond bounds (1).'

I've got an array of information being displayed at my tableview, and when I hit a button I'm wanting it to scroll down to a certain cell.

Initially I thought I was getting that error because of the way I was getting my index to jump to: 

 if let index = peopleListArray.index(where: { $0.UID == currentUser }) {
       print(index)
            let NSIndex = NSIndexPath(index: Int(index) )
            tableView.reloadData()
            print(peopleListArray.count)
            print(NSIndex)
            tableView.scrollToRow(at: NSIndex as IndexPath , at: .top, animated: true )
        }

But then I replaced "let NSINDex... with 

 let NSIndex = NSIndexPath(index: 1 )

and it's still throwing the same error.

when I'm printing out my array count and my NSIndex I'm always getting an 8 for the count (which is correct) and I'm getting 3 for the NSINdexPath which is correct.

I could understand the error if the 3 was out of bounds of my array.count but it definitely isn't.

any ideas?

There are two options that may be wrong here:

  1. you passed a section that is out of bounds, i.e with index less than 0 or bigger than the specified number of sections in

     numberOfSectionsInTableView:(UITableView *)tableView

So just try to use 0 for the section number first.

  1. the index of the row is out of bounds for the specified section (they can be different for each section)

It seems the issue you are having is with the section and not with the row. Try to build the index like this:

NSIndexPath(item: index, section: 0)

Note the section is set to 0.
