SWIFT - UIimagepicker to assign image into an array - arrays

Question

Basically I would like my Imagepicker to be able to assign the captured a image to a new row in tableview each time the user input a name and select a image for this name. I encounter at least 2 types of errors for below codes:
1) 'UIImageView' is not a subtype of 'NSString' error being displayed besides "cell.itemImage.image = UIImage(named: selectedImageArray[indexPath.row])"
2) a problem of how to access for example '.contentMode' and '.clipsToBounds' properties of the assigned image (being each in the array to be assigned to the tableview)
Appreciate anyone's help on these~~
Tableview Controller:
import UIKit
class AddPostItemTableViewController: UITableViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UITableViewDelegate {
#IBOutlet var titleName: UILabel!

// Initialization code

override func setSelected(selected: Bool, animated: Bool) {

// Configure the view for the selected state

Answer 1

The first error suggests that your array contains UIImageViews, not names of images. The UIImage(imageNamed: ) accepts name of image as a string. You probably need something like
cell.itemImage.image = selectedImageArray[indexPath.row].image
or if you want to use the UIImage(imageNamed:), use your name array instead.
With regards to the second issue, you can put a dot after the [indexPath.row] to access properties of the stored object at the given index like I did above. Or you can do it in a more readable way:
var myImage = selectedImageArray[indexPath.row]
myImage.someProperty
