Error in UIImageView Animation - ios

Question

Absolute Swift beginner here.
I have been trying to get a simple set of png's to animate.
Here is what I have:
Any help would be much appreciated.
Thanks
#import <UIKit/UIKit.h>
class ViewController: UIViewController {
#IBOutlet var myImageView : UIImageView
#IBOutlet var animationBtn : UIButton
var imageList = UIImage[]()
#IBAction func animationBtnClicked(sender : AnyObject) {
startAnimation()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
for i in 1...13
{
let imageName = "\(i)"
imageList += UIImage(named: imageName)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func startAnimation() -> Void
{
if !myImageView.isAnimating()
{
myImageView.animationImages = imageList
myImageView.startAnimating()
animationBtn.setTitle("Stop Animation", forState: UIControlState.Normal)
} else
{
myImageView.stopAnimating()
myImageView.image = UIImage(named:"bomb.jpg")
animationBtn.setTitle("Start Animation", forState: UIControlState.Normal)
}
}
}
Here is the adjusted code if it helps anyone.
Cheers
import UIKit
class ViewController: UIViewController {
#IBOutlet var myImageView: UIImageView!
#IBOutlet var animationBtn: UIButton!
var imageList = [UIImage]()
#IBAction func animationBtnClicked(sender: AnyObject) {
startAnimation()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
for i in 1...99
{
let imageName = "\(i)"
imageList.append(UIImage(named: imageName)!)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func startAnimation() -> Void
{
myImageView.animationImages = imageList
myImageView.startAnimating()
}
}

Answer 1

Those errors messages shows the exact issue.
Issue 1
For fixing has no initializers, you need implement at-least one init function in your class.
Issue 2
For fixing IBOutlet has non-optional, you need to change your IBOutlet variables to optionals.
#IBOutlet var myImageView : UIImageView!
#IBOutlet var animationBtn : UIButton!
Issue 3
For fixing that [UIImage] is not identical to UInt8. The += can't be used to append a single UIImage to [UIImage]
You need to change:
imageList += UIImage(named: imageName)
to
imageList.append(UIImage(named: imageName))
