Launch Screen Transition

How do I create a seamless transition between my launch screen storyboard and my main storyboard? At the moment, I only have a solid color for my launch screen for simplicity, and the first screen of my app is the same color, but with a logo, so it should be a rather smooth transition. Yet when I run my app, there's always a jarring flash in between the launch screen and the first screen of my main storyboard. How do I add some sort of transition between the two, such as fade or crossfade or blur in etc.?
Thank you!
Now that I take a closer look, it appears as though there is a black screen flashed in between the launch screen and the first scene of my game. How do I rid of this black screen?
I think this may be where things are going wrong, but I don't quite understand how to fix it. I get a white screen, then the launch screen, then a black screen, then my app begins
