Slow gif animation with SwiftGif

i use this SwiftGif library. I put some gif into UIImageView. This is my code:

dispatch_async(dispatch_get_main_queue(),{
    self.img1.image=UIImage.gifWithURL("http://mywebsite/img1.gif")
    self.img2.image=UIImage.gifWithURL("http://mywebsite/img2.gif")
    self.img3.image=UIImage.gifWithURL("http://mywebsite/img1.gif")
})

The gifs are shown correctly but the animation is slow. How can I fix this? Thanks!

if your gif size is too big then Use a webview to load gif

Add a WebView,

Add gif file to your project directory then add this following code :

let url = Bundle.main.url(forResource: "your-gif-name", withExtension: "gif")!
let data = try! Data(contentsOf: url)
webView.load(data, mimeType: "image/gif", textEncodingName: "UTF-8", baseURL: NSURL() as URL)

Note: Make your gif file's height and width as same as the webview using any gif editing website

Paste the following code in UIImage+Gif.swift where calculation of duration is done in in animatedImageWithSource function:

 // Calculate full duration
let duration: Int = {
    var sum:Double = 0

    for val: Int in delays {
        let newVal =    Double(val) - (Double(val)/1.5)//Modified calculation to speed up the animtion in gif
        //sum += val :default calculation
        sum += newVal
    }

    return Int(sum)
    }()

I assume that your gif file size is too big? or the time is too long? because SwiftGif is base on UIAnimatedImage.

And also control your gif frame of 9, 10, 20, 30, 40, and setup GCD to 1.
