Swift set button image

Question

When I try to change button's image when button pressed but it just shows a blue square as button's image

@IBAction func button(_ sender: Any) {
     buttonOutlet.setImage(#imageLiteral(resourceName: "thing"), for: UIControl.State.normal)
}

are you sure you changing the same button, and with correct image — Iraniya Naynesh, Apr 28 '19 at 09:17
yourButton.setImage(UIImage(named: "Your_Image_Name"), for: .normal), this should always work, unless your button is in different state other than normal, or you have set image for different state — Iraniya Naynesh, Apr 28 '19 at 09:20

From Apple documentation:

A control becomes highlighted when a touch event enters the control’s bounds...

button.setImage(UIImage(named: "button_normal_state"), for: .normal)
button.setImage(UIImage(named: "button_pressed_state"), for: .highlighted)

Just recheck that you have "thing" - image in your target.

button.setImage(UIImage(named: "thing"), for: [.selected, .highlighted])
