Make sure that your LaunchScreen file is selected in the Project General Settings, like so:

Also, if you're using a storyboard for your Launch Screen, make sure there the only view controller is set as initial view controller., like so:

EDIT:

So if restarting the device did not work for you, try the following:

1. Re-adding the image into your Assets.xcassets.
2. Renaming the image.
