Determine Segue Based on picker selection IOS, swift - ios

Question

I have a picker with two options currently, and what I am looking for is, based on the selection made in the picker, to determine the next viewController below is what I tried to use however, I immediately got an error stating the last "if" statement should be converted into a let statement. Below is the code for my picker and attempt to lead into associated segue.
import UIKit
import Firebase
import CoreData
import CoreLocation
class SchoolPickerViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
#IBOutlet weak var SchoolPicker: UIPickerView!
let pickerData = ["Ohio State University", "University of Rochester"]
override func viewDidLoad() {
super.viewDidLoad()
SchoolPicker.dataSource = self
SchoolPicker.delegate = self
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return pickerData.count
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return pickerData[row]
}
#IBAction func schoolSelectorGoButton(sender: AnyObject) {
if pickerData = "Ohio State University" {
performSegueWithIdentifier("ohioStateSelected", sender: sender)
}
if pickerData = "University of Rochester" {
performSegueWithIdentifier("rochesterSelected", sender: sender)
}
}
}

Answer 1

u should get selected picker data from Array
define
var selectedIndex = 0
then in this line
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String?
{
selectedIndex = row
return pickerData[row]
}
and in this action
#IBAction func schoolSelectorGoButton(sender: AnyObject) {
if pickerData[selectedIndex] == "Ohio State University" {
performSegueWithIdentifier("ohioStateSelected", sender: sender)
}
}
