"Array index out of range" when choosing photos in Swift - ios

Question

I cant figure out what's the problem here.
I have 6 images and when i click on them it popsup a image picker. If i choose a photo with a sequence, like 1,2,3,4,5,6... it works. But when i choose the first photo that's not the first one (array[0]), i get an error:
`$"Array index out of range"
Here is my code:
class SecondViewController: UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate {
var imagemEscolhida = -1
#IBOutlet var firstImageView: UIImageView!
#IBOutlet var secondImageView: UIImageView!
#IBOutlet var thirdImageView: UIImageView!
#IBOutlet var fourthImageView: UIImageView!
#IBOutlet var fifthImageView: UIImageView!
#IBOutlet var sixthImageView: UIImageView!
#IBAction func firstImageButton(sender: AnyObject) {
imagemEscolhida = 1
abreBibliotecaFotos(imagemEscolhida)
}
#IBAction func secondImageButton(sender: AnyObject) {
imagemEscolhida = 2
abreBibliotecaFotos(imagemEscolhida)
}
#IBAction func thirdImageButton(sender: AnyObject) {
imagemEscolhida = 3
abreBibliotecaFotos(imagemEscolhida)
}
#IBAction func fourthImageButton(sender: AnyObject) {
imagemEscolhida = 4
abreBibliotecaFotos(imagemEscolhida)
}
#IBAction func fifthImageButton(sender: AnyObject) {
imagemEscolhida = 5
abreBibliotecaFotos(imagemEscolhida)
}
#IBAction func sixthImageButton(sender: AnyObject) {
imagemEscolhida = 6
abreBibliotecaFotos(imagemEscolhida)
}
func abreBibliotecaFotos (img: Int )
{
imagePicker.allowsEditing = false
imagePicker.sourceType = .PhotoLibrary
presentViewController(imagePicker, animated: true, completion: nil)
}
let imagePicker = UIImagePickerController()
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
firstImageView.contentMode = .ScaleAspectFit
restaurante.imagem.insert(pickedImage, atIndex: imagemEscolhida-1)
switch imagemEscolhida
{
case 1:
firstImageView.image = restaurante.imagem[0]
case 2:
secondImageView.image = restaurante.imagem[1]
case 3:
thirdImageView.image = restaurante.imagem[2]
case 4:
fourthImageView.image = restaurante.imagem[3]
case 5:
fifthImageView.image = restaurante.imagem[4]
case 6:
sixthImageView.image = restaurante.imagem[5]
default:
println("Something else")
}
picker.dismissViewControllerAnimated(true, completion: nil)
}
dismissViewControllerAnimated(true, completion: nil)
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
dismissViewControllerAnimated(true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
imagePicker.delegate = self
}
}

Answer 1

You should initialize the array before you use it in the correct size. I would like to refer to my answer to a really similar question.
So initialize it from 0 to 5 at definition then your code should work.

Answer 2

It looks like the restaurante.imagem array is empty and your code crashes because you try to insert something at index which is higher than the maximum index of the array - which is 0.
The line to blame is:
restaurante.imagem.insert(pickedImage, atIndex: imagemEscolhida-1)
