Styling the Buttons and Slider
Update 10/30/19: In Xcode 11.1, by default Xcode will not render the background image for the button as shown. However there is a simple workaround:
- Open Assets.xcassets.
- Select the Button image.
- In the inspector, under ImageSet, set Render As to Original Image.
For more details, see the forum discussion.
