iPhone Retina (4-inch) launch image for iOS 7.0 and later not found?

I’ve recently been running into issues with uploading my app to the app store for use with testflight to show some clients the progress of the app I’ve been developing using openFrameworks. However, I’m running into this issue with Xcode’s “organizer” with the following error:

“An iPhone Retina (4-inch) launch image for iOS 7.0 and later is required.nib’ was not found. Please ensure the specified file is included in the bundle with any required device modifiers appended to the filename.”
(it does this twice for ipad and iphone devices [universal])

I’m not sure if the following could have been a contributor to the problem, but it was recommended to me that I should use the image catalog system to add the icons and load screens.

Any ideas?
