UIImage not displaying using Swift

Question

Code written in Swift for displaying UIImages works in the iOS 8.0 simulator but not on a phone running IOS 7.0 for some reason.

let image1 = UIImage(named: "img1")
let imageview = UIImageView(image: image1)
self.view.addSubview(imageview)

let image2 = UIImage(named: "img2")
let button = UIButton(frame: CGRect(origin: CGPoint(x: 0, y: 100), size: image2.size)
button.setImage(image2, forState: UIControlState.Normal)
self.view.addSubview(button)

The images are in the right place with the right size and valid references, they're just not being displayed, except on the simulator running iOS 8.

Is this a problem for anyone else?

EDIT: Deleting from Images.xcassets, cleaning the project and copying the files into the bundle itself seems to work for me.

Answer 1

Inorder to display images you have to change the code in following way

let image1 = UIImage(named: "img1.jpg")
let imageview = UIImageView(image: image1)
self.view.addSubview(imageview)

let image2 = UIImage(named: "img2.jpg")
let button = UIButton(frame: CGRect(origin: CGPoint(x: 0, y: 100), size: image2.size)
button.setImage(image2, forState: UIControlState.Normal)
self.view.addSubview(button)

Remember swift is not supporting .png format images, It is supporting .jpg format.

Answer 2

You would check if the image was added to your framework, if that is unchecked you are not able to load the resource, but if you check it, the image will be loaded

Answer 3

I tried your code in iOS 8-Simulator and on my iOS 7 device and it did what it should do. So no, in my case I don't see a problem.

I changed img1 to img1.JPG (name of file) and img2 to img2.png. And I copied the images directly into the folder where the view controller is..
