error: "Thread 1: EXC_BAD_ACCESS(Code=EXC_I386_GPFLT) - ios

Question

I need help here. I am trying to use core data to implement an app. But on line 52 -
myHood.setMyHoodImg(addHoodImg.image!))
I having an error each time a click the button to create a new hood. The error:
"Thread 1: EXC_BAD_ACCESS(Code=EXC_I386_GPFLT)
Here is the code:
import UIKit
import CoreData
class CreateHoodVC: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBOutlet weak var hooddesc: UITextField!
#IBOutlet weak var addHoodImgBtn: UIButton!
#IBOutlet weak var addHoodImg: UIImageView!
var imagePicker: UIImagePickerController!
override func viewDidLoad() {
super.viewDidLoad()
imagePicker = UIImagePickerController()
imagePicker.delegate = self
addHoodImg.layer.cornerRadius = 4.0
addHoodImg.clipsToBounds = true
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
imagePicker.dismissViewControllerAnimated(true, completion: nil)
addHoodImg.image = image
}
#IBAction func addImage(sender: AnyObject!){
presentViewController(imagePicker, animated: true, completion: nil)
}
#IBAction func createHood(){
if let hoodDescription = hooddesc.text where hoodDescription != ""{
let app = UIApplication.sharedApplication().delegate as! AppDelegate
let context = app.managedObjectContext
let entity = NSEntityDescription.entityForName("MyHood", inManagedObjectContext: context)!
let myHood = MyHood(entity: entity, insertIntoManagedObjectContext: context)
myHood.myHoodDescription = hoodDescription
myHood.setMyHoodImg(addHoodImg.image!)
context.insertObject(myHood)
do {
try context.save()
} catch {
print("Could not save new Hood")
}
}
}
}

it's really simple:
if You write:
myHood.setMyHoodImg(addHoodImg.image!)
you are supposing addHoodImg.image DOES exist, but on first run, is NIL, if You did not choose an image.
so 2 ways:
1) simply write:
if let hoodDescription = hooddesc.text where hoodDescription != "" , let img = addHoodImg.image {
2) disable button on start AND enable after choosing and image.
Hope this help.
ps I have a fully functional proto here with (reduced!) classes you use.
