Chapter 1 question about background

When i set my background and i run the simulator on iphone 6 i have black borders on the side of my screen. The image “background1” does not fill the background of my iphone.

When i look at the code that was in the folder of this tutorial it is 100% the same as the code i typed in my project of the app. And when i run the simulator on the code from the “final” map
it shows the image “background1” over the whole screen.

Please help ?

Have you checked if the image changed from the starter to the final project?
