Better not to hardcode the Inset values as it might based on the orientation of the device.

Code:

func setTableViewContentInset() {

    let contentInsetHeight = topLayoutGuide.length
    let contentInset = UIEdgeInsetsMake(contentInsetHeight, 0, 0, 0)

    tableView.contentInset = contentInset
    tableView.scrollIndicatorInsets = contentInset
}

func scrollToTop() {

    if tableView.indexPathsForVisibleRows?.count > 0 {

        let topIndexPath = NSIndexPath(forRow: 0, inSection: 0)

        tableView.scrollToRowAtIndexPath(topIndexPath, atScrollPosition: .Top, animated: false)
    }
}

func scrollToTopOfVisibleCells() {

    if let visibleIndexPaths = tableView.indexPathsForVisibleRows where tableView.indexPathsForVisibleRows?.count > 0 {

        let topMostVisibleIndexPath = visibleIndexPaths[0]

        tableView.scrollToRowAtIndexPath(topMostVisibleIndexPath, atScrollPosition: .Top, animated: false)

    }        
}

//MARK: Load Views
override func viewDidLoad() {
    super.viewDidLoad()

    setTableViewContentInset()
}

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    scrollToTop()
}

//MARK: Trait collection change
override func traitCollectionDidChange(previousTraitCollection: UITraitCollection?) {
    super.traitCollectionDidChange(previousTraitCollection)

    setTableViewContentInset()
    scrollToTopOfVisibleCells()
}
