How to get a random image from a folder in swift?

So far I have created a folder of images and I am able to assign 1 of the images to a


But what I want to do now is create a random generator, that will pick a random image from the folder, so if I was to create a button, I could display all of the images separately and randomly on a single

However, this folder is going to have more than 100 images, so I don't want to hard code each one into an array. Also, the names of the image has to be unique to the image itself.

I have been searching online but cannot find information on how to code what will suit my needs. So how would I get and display a random image(s) from a folder in swift?

You can name your images like this


Then use this code to populate your UIImageView

let numberOfImages: UInt32 = 100
let random = arc4random_uniform(numberOfImages)
let imageName = "image_\(random)"
imageView.image = UIImage(named: imageName)


Since you don't want to rename your images you can create a plist file (type Array) where you put all the names of your images

enter image description here

And finally

func loadRandomImage() {
    let path = NSBundle.mainBundle().pathForResource("Images", ofType: "plist")!
    let names = NSArray(contentsOfFile: path) as! [String]
    let random = Int(arc4random_uniform(UInt32(names.count)))
    let imageName = names[random]
    imageView.image = UIImage(named: imageName)
