Filtering Apostrophes (special characters) in UISearchBar – Swift, Xcode

I currently have a UISearchBar that works fine, however, I’ve noticed that when entering apostrophes in the searchBar it does not return any results. For example: If I have a String: Bob’s if I search Bob it returns said string, however, as soon as I enter the apostrophe in the searchBar: Bob’ the searchBar returns no results.

I’ve searched online for solutions, however, have not found anything that works. Any response would be greatly appreciated, thanks.

UISearchBar Code:

    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
    if searchText.isEmpty {
        filteredData = data
    } else {
        filteredData = data.filter{$0.title.range(of: searchText, options: .caseInsensitive) != nil }
    }
    self.tableView.reloadData()
}

}

Struct:

struct Category {
    let title: String

    let items: [String]
}

Array:
Category(title: "Bob's ", items: ["Data: xxx", "Data: xxx", "Data: xxx",]),

cellForRowAt Func:

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! MyTableViewCell

        let title = filteredData[indexPath.row].title

          cell.myLabel.text = title

          cell.myImg.image = UIImage(named: title + ".png")

          return cell

    }

}

Output returned in console when apostrophe is typed in searchBar:
filteredData = []
