Realm prevent crash for `Index x is out of bounds (must be less than x)`

RealmIndexOutOfBoundsFix.swift

// Use
if indexPath.row < arrayOfObjects.count {
    cell.label.text = arrayOfObjects[indexPath.row]
} else {
    // Handle non-existing object here
}

// Example: 
if let wheel = wheel, let row = indexPath?.row, row < wheel.comments.count {
    let comment = wheel.comments[row]

    nameLabel.text = comment.userName
    bodyLabel.text = comment.text
}
