Static TableView gets NSRangeException

I have a UITableViewController with static cells, and when I run the app and click on the button that leads to it, I get a SIGABRT signal in AppDelegate.

I tried to find unused outlets, but it didn't work.

Here is the Console Log:

The UITableViewController Code:

import UIKit
import os.log

class SettingsTableViewController: UITableViewController {

    // MARK: Properties
    @IBOutlet weak var noteDisplayKindSwitch: UISwitch!

    override func viewDidLoad() {
        super.viewDidLoad()

        notedisplayKindSwitch.setOn(Settings._displaynotesAsNames, animated: false)
    }

    @IBAction func ChangeNoteDisplayKind(_ sender: UISwitch) {
        Settings._displayNotesAsNames = sender.isOn

    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
        return 2
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 3
    }
}

Somewhere in your tableView:cellforRowAtIndexPath method, there's an empty array but you're trying to access the element at index 1.

You are using static cells. There is no reason to implement numberOfSections and numberOfRowsInSection because those are specified by the static layout in the Storyboard.

Because you have implemented:

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 3
}

you are telling iOS that every section has 3 rows, which is a lie. So iOS tries to access the second row of your first section and crashes with array index out of range because that section has just 1 row.

So, delete the implementations of numberOfSections and numberOfRowsInSection and you should be good to go.
