```
private  var contactsWithSections = [[WPH]]()

```

WPH have following properties:

```
class WPH: NSObject {
    var fName: String? = nil
    var lName: String? = nil
    var number: String? = nil
    var email: String? = nil
}

```

I want to search based on fName i.e. in array have fname = alex, fname = alena, fname = flora

```
let searchStr = "al"

```

Then result should return objects for alex and alena
