searchBar overlapped by section header view

I put the searchBar inside the tableHeaderView. Everything works fine on iphone 6 but on iphone 5s I get this weird result?

 override func viewDidLoad() {
    super.viewDidLoad()
    tableView.delegate = self
    tableView.dataSource = self
    tableView.sectionIndexColor = Constants.Colors.ThemeGreen
    tableView.sectionIndexBackgroundColor = UIColor.clearColor()
    tableView.sectionIndexTrackingBackgroundColor = UIColor.clearColor()
    tableView.contentInset = UIEdgeInsetsMake(0, 0, CGFloat(Constants.Dimensions.TabBarHeight), 0)
    resultSearchController = UISearchController(searchResultsController: nil)
    resultSearchController.searchResultsUpdater = self
    resultSearchController.dimsBackgroundDuringPresentation = false
    resultSearchController.definesPresentationContext = true
    tableView.tableHeaderView = resultSearchController.searchBar
    resultSearchController.searchBar.sizeToFit()

 //Fetch data for the first time
    do{
      try fetchedResultsController.performFetch()
      listHeaderView?.count = "(fetchedResultsController.fetchedObjects!.count)"
    }catch{
      print("Error - Couldn't fetch list")
    }

NOTE: I'm using a NSFetchedResultController to retrieve the data

Here is the solution. Don't call sizeToFit() AFTER putting the searchBar in tableHeaderView but call it BEFORE. What the hell is going on behind the scene... I wonder..

resultSearchController.searchBar.sizeToFit() //Important to call sizeToFit BEFORE adding it to tableHeaderView or you get layout issues
tableView.tableHeaderView = resultSearchController.searchBar

It seems only below line of code does work ... nothing else seems to work right now.

self.tableView.beginUpdates()
       // self.tableView.setTableHeaderView(headerView: self.filterView!)
        //self.tableView.reloadData()
        self.tableView.layoutIfNeeded()
        self.tableView.layoutSubviews()
        self.tableView.endUpdates()

everytime your table resize or change constraints you need to call above code.

Try this it may work

resultSearchController.clipToBounds = true

You can also try the same as

searchControl.searchBar.clipToBounds = true

I think it works for your code.
