Animate Gif in Swift

Question

I've been trying to animate a GIF in Swift but it just doesn't work. I think I found a way but there's an error, please help.

Here's the code:

@IBOutlet var imageView: UIImageView!
override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
    // (Here is the error it states "Cannot assign a value of type '[UIImage?]' to a value of type '[UIImage]?'")
    imageView.animationImages = [

        UIImage(named: "logo1.jpg"),
        UIImage(named: "logo2.jpeg"),
        UIImage(named: "logo3.png")
    ]

    imageView.animationDuration = 3
    imageView.startAnimating()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
    // ...
}

How to load GIF image in Swift?

As far as the issue in you code is, as already 'Leo Dabus' pointed out, is you are not un-wrapping the UIImage instances. Try same code with the following modifications.

imageView.animationImages = [

        UIImage(named: "logo1.jpg")!, //File Extension would not be required if .png
        UIImage(named: "logo2.jpeg")!,  //File Extension would not be required if .png
        UIImage(named: "logo3.png")!
    ]

    imageView.animationDuration = 3
    imageView.startAnimating()

You just need to unwrap the optional UIImage returned by UIImage(named:) method. Try like this:

class ViewController: UIViewController {
    @IBOutlet weak var imageView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        imageView.animationImages = [
            UIImage(named: "logo1")!,
            UIImage(named: "logo2")!,
            UIImage(named: "logo3")!]

        imageView.animationDuration = 3
        imageView.startAnimating()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

That still doesn't work because the problem is the imageView.animationImages – Ethan Marcus Sep 04 '15 at 04:46
Can you elaborate on that reason? – Leo Dabus Sep 04 '15 at 04:49

You better double check your code and also if you have properly added the images listed there to your project Images.xcassets – Leo Dabus Sep 04 '15 at 04:59

I have created one example for you.

Here is code:

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var imageView: UIImageView!
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        imageView.animationImages = [
            UIImage(named: "1")!,
            UIImage(named: "2")!,
            UIImage(named: "3")!,
            UIImage(named: "4")!,
            UIImage(named: "5")!,
            UIImage(named: "6")!,
            UIImage(named: "7")!,
            UIImage(named: "8")!,
            UIImage(named: "9")!,
            UIImage(named: "10")!,
            UIImage(named: "11")!,
            UIImage(named: "12")!

        ]

        imageView.animationDuration = 3
        imageView.startAnimating()
    }
}

You can see Result HERE.

And HERE is sample project.
