I have an old project and convert into swift 3. It have simple launch screen storyboard . Launch screen storyboard have an image as logo of company, This image not showing into device but i replace that image with another image , replaced image showing perfect. Launch screen behave strange.
Just delete launch screen storyboard and make a new launch screen storyboard then new image view on it .Make sure your image size 1x,2x,3x available.
